I have handled dozens of villa and apartment-style residential projects. The biggest lesson I've learned is that when choosing materials, you should pick those that save time, are durable, and cost-effective. And prefabricated EPS insulation wall panels are my favorite in recent years. Compared to on-site poured wall panels, this stuff is installed much faster and the quality is particularly stable. After working with so many suppliers, I have the greatest confidence in Longer's prefabricated EPS wall panels - they are lightweight, easy to modify in size, and reliable without any risks. Today, let's talk about why these wall panels are suitable for residential projects, how practical Longer's custom size options are, and how their bulk supply is friendly to our construction teams.  Why do I strongly recommend using prefabricated EPS wall panels for residential buildings?  The construction period for residential buildings is very tight, especially for multi-unit apartments. Even a slight delay in the process would cause the costs to skyrocket. Prefabricated EPS insulation wall panels can precisely address this issue by simplifying the installation process. They are standardized in the factory, with each wall panel having the same size, density, and insulation effect. In contrast, on-site pouring is prone to human errors and has to be halted in case of wind or rain, making it highly unstable.  Time-saving installation: Prefabricated vs. traditional wall panels - the difference is huge.  Last time, when I was working on a 20-unit apartment building project, I replaced the traditional concrete wall panels with Langjin's lightweight EPS wall panels. The result was simply amazing. Previously, when using traditional wall panels, we had to rent heavy machinery for hoisting, and the installation and curing of a single panel alone took several hours. However, the prefabricated plates of Langjin were extremely lightweight. Just a few workers could lift and install them, and there was no need to find large equipment at all. The wall insulation project that originally took 4 weeks to complete was finished in just 10 days - the efficiency was increased by 75%! Not only was the construction schedule not delayed, but the labor cost was also reduced by a large amount.  Lightweight design: Small details that save a lot of money during residential construction  The wall panels are lightweight, which is extremely important for residential construction sites - many residential plots are narrow and large machinery simply cannot enter. Previously, when we were building townhouses in the city center, the inner area was inaccessible to machinery, and we relied on workers to carry the sturdy prefabricated EPS wall panels in and install them. This saved a significant amount of machinery rental fees. Moreover, the lightweight wall panels exert less pressure on the foundation, allowing for simpler and more cost-effective foundation design. These are invisible cost savings.  Longer Customized Size EPS Wall Panels: Precisely Tailored to Meet Your Project Requirements  Where are there standardized specifications for residential projects? Whether it's ordinary commercial housing or custom villas, the sizes and shapes vary greatly. General wall panels simply aren't sufficient. Langjin does this particularly well by providing custom-sized EPS insulation wall panels. You can adjust the size to any specification you need. Need to add longer boards for high ceilings? Want to do energy-saving design and need to add thickness? Just tell them and they can make it for you.  Below is the detailed information about the customized service for Langjin Prefabricated EPS Wall Panels, specifically designed to meet the needs of residential construction teams:   Customization Type Available Range Additional Cost MOQ Size Customization (Length x Width) 1000mm-3000mm (Length) x 600mm-1200mm (Width) 5% of total price 200m² Thickness Customization 30mm-150mm 3% of total price 200m² Special Shape Cutting (Arches, Angles) Custom Design Based on Drawings 8%-15% of total price (varies by complexity) 100m²   Previously, I undertook a custom villa project. The owner wanted to have a curved wall in the living room, with a very unique design. The Langjin team took our construction drawings and directly produced precast plates with a curved shape. They were transported to the site and installed seamlessly. There was no need for on-site cutting and sanding, saving time and perfectly replicating the design effect - this would be impossible to achieve with traditional wall panels. Practical tips for choosing prefabricated EPS wall panels for residences  Prefabricated EPS wall panels also come in different quality levels. Based on my experience, when choosing, the following points should be given priority consideration:  - Prefabricated quality: Make sure to choose products produced by the factory in a standardized manner to avoid inconsistent quality. Each board of Langjin has been tested, and its density and insulation effect are consistent. You can use it with peace of mind.  Lightweight yet durable: It must be easy to install and also able to withstand daily use. The Langjin wall panels strike a perfect balance, being lightweight yet not brittle.  - Customization Flexibility: When undertaking residential projects, there will inevitably be special designs. Choose suppliers who can flexibly modify dimensions and shapes. Don't go for those that can only provide fixed specifications. Otherwise, it will delay the construction schedule and limit the design options.  - Thermal insulation effect: Homeowners are concerned about energy consumption and electricity bills. Longjin's prefabricated EPS wall panels have a high insulation coefficient, making the house warm in winter and cool in summer. The homeowners are also satisfied.  Longer Batch Supply: Essential Service for Residential Construction Teams  When it comes to projects like apartment buildings or large residential complexes, the reliability of mass production is extremely important. Langjin's mass production is very reliable, with stable quality, timely delivery, and reasonable prices.  The minimum order quantity for their custom orders is only 200 square meters. Our construction team doesn't need to invest too much capital when preparing the materials. Even for large orders of tens of thousands of square meters, they can still accept them, and the delivery time will not be delayed. For batch orders, there will be a dedicated customer manager to follow up from the quotation to the shipment, and any issues can be communicated at any time. It's particularly convenient.  Moreover, there will inevitably be temporary changes in residential projects, such as increasing the quantity or modifying the dimensions. The Langjin team responds very quickly and can promptly adjust the orders, ensuring that the project does not get stuck.  The prefabricated EPS insulation wall panels have truly enhanced the efficiency of residential construction. They save time and cost, and the quality is stable. Langjin's products are more thoughtful, lightweight, customizable, and reliable for large-scale supply. They are particularly suitable for single-family villas, apartment buildings, or large residential complexes.  Contact Lang Jin immediately and tell them your customized size and batch requirements. They will provide you with a detailed quote and even send you free samples for you to test. Believe me, using their prefabricated EPS wall panels, your next residential project will go smoothly.

  Anyone working in exterior insulation knows the biggest nightmare: tiling over insulation layers, only to have the tiles loosen and detach after just a couple of years. This is especially true when using XPS (extruded polystyrene) boards as insulation— their extremely smooth surface prevents cement mortar from adhering properly, causing tiles to become loose within days. The most frustrating issue for clients is finishing the insulation layer only to find that tiling fails, resulting in rework costs higher than starting over. Some projects use all-ceramic glazed tiles, so slippery they resemble mirrors—standard installation methods simply can't hold them securely. For even more demanding applications, people want to install marble or rock slabs directly onto insulation boards. But due to the heavy weight of stone, the insulation board can't bear the load, eventually causing entire slabs to fall off over time—a risk that goes far beyond financial loss.    Our LONGER team conducted extensive on-site testing and found that the root cause of the problem lies not in the tiles or stone, but in inadequate surface treatment of the insulation board. XPS boards are inherently dense and smooth, preventing cement mortar from penetrating. As a result, bonding strength relies solely on minimal physical friction—how long can that last? That's why we developed this specialized XPS backer board: essentially, we create a textured, rough surface on the XPS board before it leaves the factory, specifically designed for tiling and stone installation. When applied to XPS (Extruded Polystyrene Board), the backer features built-in grooves and ridges that allow cement mortar to grip firmly, creating a bond so strong it feels like the materials have grown together once cured. Using this backer board with all-ceramic glazed tiles—even large-format glazed tiles—ensures they remain perfectly stable on walls without shifting. When installing marble or rock slabs, there’s no longer any need to worry about the weight crushing the insulation layer; the backer evenly distributes stress, keeping the stone as steady as a mountain.  Customer feedback is the most telling: previously, after tiling and a half-month curing period, we still had to tap occasionally to check for hollow spots. Now, using LONGER backer boards, with normal construction and just seven days of curing, when I tap it myself with a hammer, the sound is solid—no hollow areas at all. Moreover, the insulation performance remains completely unaffected—effective thermal insulation where needed, and excellent soundproofing where required. Its application is clear: wherever tiles or stone cladding are used in exterior wall insulation systems, this product can be applied. In one sentence, its value lies in making insulation layers suitable for tiling—and ensuring the tiles stay firmly attached.    Product Features:   ① Mechanical interlocking texture: The surface is not coated but features physically pressed grooves and ridges, allowing cement mortar to penetrate the gaps and create strong bonding.   ② Waterproof and freeze-thaw resistant treatment: The edges of the back panel are sealed, protecting the adhesive layer from rainwater and freeze-thaw cycles, ensuring long service life.   ③ Integrated interface agent: Comes with a pre-applied interface treatment at the factory, eliminating the need for additional primer—mortar can be applied directly after installation.  Tips: ① Before tiling, blow off the dust from the back of the board—don't wipe with a damp cloth, as excess moisture can weaken adhesion. ② When installing large stone slabs on walls, use double-sided tape to temporarily secure them, then remove it after the mortar has cured to prevent slippage or displacement.    Insulation tile installation is most prone to tile detachment. LONGER XPS backing board effectively solves the long-standing problem of poor adhesion on insulation layers, saving time and effort.        

Let's be real about wall panels. You pick one, install it, and hope it holds up. But a lot of them don't. Some swell up when the air gets damp. Others start looking dingy after a few months. The cheap ones? They smell like a factory for weeks. You end up regretting the choice, and redoing everything costs more than doing it right the first time. That's where LONGER comes in. These Carbon Crystal Wall Panels are made from high-density carbon crystal composite. Not the same stuff you see in regular wood-plastic boards. If you've dealt with wpc wall cladding before, you know it's decent, but it can still have issues in really wet spots. LONGER's material is different. It doesn't soak up moisture. It doesn't give mold a place to grow. It doesn't bend or buckle over time. Bathroom, kitchen, basement, you name it. The look is another thing. Instead of printing a pattern on top, they use a heat-transfer process. That means the finish goes deeper, so it won't peel or flake off years later. The texture feels like real wood grain or stone, but it costs way less. And it's tough. Scrape it with a key, nothing happens. Wipe it with a rag, it's clean. If you have kids or pets making messes, you'll appreciate that. Installing it is pretty straightforward. There's a snap-on locking system. You don't need glue. You don't need to put up a plywood base first. Just mount it right on the wall. That alone cuts the work time by half. Less labor, less hassle. The panels also help with temperature. They add a bit of insulation, so rooms stay warmer in winter and cooler in summer. That means less running the heater or AC. Some people bring up wpc exterior wall cladding when talking about wall panels. Those are built for outdoor use, handling sun and rain. For inside, LONGER focuses on indoor needs. The carbon crystal material meets E0 standards for formaldehyde. You can move in right after installation. No need to wait weeks for the smell to fade. Plus, the carbon crystal emits far-infrared radiation, which gives a subtle warmth that regular panels don't have.   Product Features: 1.High-density carbon crystal base, won't swell, mold, or warp in wet areas, long service life. 2.Heat-transferred surface, realistic wood or stone texture, scratch-resistant, easy to clean, kid and pet friendly. 3.Snap-on joint installation, direct mount on raw walls, no glue or base needed, cut labor time by half.   Tips: 1.Fill any major wall holes with cement before installation for smoother joints. 2.Use matching trim strips for clean corners and a uniform look. 3.Clean with a damp cloth only, avoid strong acid or alkaline cleaners.   LONGER doesn't complicate things. Good base material. Quality surface finish. Simple installation. Safe for indoor use. You put it up once, and it stays good for years. Whether it's a home, a hotel, or an office, these panels handle the job. No fuss, no constant upkeep, just a wall that works.  

Let's talk about the pitfalls in the decoration industry. When using traditional Wall Tile, over time, they tend to become loose and fall off, and the gaps can accumulate dust and get moldy. Marble slabs look grand, but this Marble And Rock Board is not only expensive, but also requires professional installers. Even if there are cracks or damages, they cannot be repaired. The total cost of transportation and installation can easily deplete your budget. If you are a construction supervisor or designer, or if you are planning to do the decoration yourself, the most worrying thing is choosing the wrong wall material. Later, it may crack, change color, and be difficult to maintain, causing endless troubles when you move in.  The LONGER carbon crystal wall panel uses different materials. It belongs to a new type of building material. The board is equipped with a carbon crystal heating layer. Not only can it be used as a wall panel, but it can also assist in heating in winter. The surface texture is exactly like that of real stone. The texture you desire for the stone slab it has. However, its weight is several times lighter than Marble And Rock Board, and it can be moved by one person. Installation does not require cement or sand. It can be directly screwed onto the wall, even in a raw building, and the construction period can be reduced by more than half.    Product Features:  1.Carbon crystal heating technology can be used as an indoor heater in winter, saving you the cost of buying an additional heater. 2.The texture is highly realistic like marble, and it looks exactly the same as real granite slabs. The cost is only one-third of that of real granite. 3.Zero formaldehyde materials. You can move in right after installation, without the need for ventilation to disperse the odor.   Tips:  1.When cutting, use ordinary woodworking saw blades. Don't use stone cutting blades as they are prone to chipping. 2.For the corners and bends, it is recommended to use the matching right-angle lines. This will give a neat and sturdy finish. 3.And let's be more specific. Just think about it. After installing traditional Wall Tiles, the gaps will turn black after two years and you'll have to hire someone to do the grouting. With Marble And Rock Board, if you accidentally bump it, it will be a dent and you'll have to spend a lot of money to replace it. The LONGER carbon crystal board has a wear-resistant layer on its surface. Even if a key scratches it, there won't be any marks. Just wipe it with a damp cloth and it will be clean. Moreover, it comes with an insulation layer, so the wall won't be cold in winter, which can save some heating costs.    A friend of mine runs a guesthouse. The wallpaper on the walls of the guest rooms used to get dirty easily when there were many guests. They had to replace it several times, which was really annoying. After replacing the entire house with LONGER carbon crystal wall panels, all the guests commented on their photos on WeChat Moments that it looked very elegant. Just wipe it with a cloth when it gets dirty, and they no longer had to worry about the walls. He even did the math himself. Although the panels were a little more expensive than ordinary wall panels, they saved all the maintenance costs in the future, and it turned out to be a better deal.    When it comes to decoration, the walls are the most important aspect of a home. Don't spend a lot of money on the floor while skimping on the walls. LONGER carbon crystal wall panels. Once installed, you don't have to worry about it. Your life will be peaceful and reliable.

Those in the construction industry all know that the XPS backing plate, EIFS backing plate, and XPS backing board we use often encounter problems such as leakage, deformation, and hollowing, which not only cost a lot of money and effort to fix later on but also delay the construction schedule and affect the quality of the building. This is something that many customers have complained to me about over the years of my work in this field. To address these issues, I would like to recommend the LONGER Professional XPS Backing Plate to everyone. This product is specifically designed to solve problems related to building insulation, waterproofing, and base support. It can be used in exterior insulation and finish systems (EIFS), damp areas in homes, and basement waterproofing. It eliminates all the problems of traditional backing plates, simplifies the construction process, and helps save a lot of costs. Once installed, it can be used for a long time without the need for repeated repairs.  Product Features  It has an outstanding waterproofing effect. It uses high-closed-cell XPS core material, which hardly absorbs water. It can effectively block water vapor from the root, preventing mold and leakage. It can be applied in damp areas like bathrooms and swimming pools, as well as in exterior wall EIFS systems.  It may look light, but it is particularly sturdy, with strong pressure resistance and stable dimensions. It is not prone to deformation or cracking, which can reduce the occurrence of hollow tiles. Moreover, it is easy to cut and the construction speed is fast, saving a lot of labor costs.  3. It has a wide range of applications. It can be used as an XPS backing board for exterior wall insulation, floor heating base, and lightweight partition walls. It can also be combined with various adhesive materials without complex processing. It is basically suitable for all kinds of construction projects.  Operation Tips  Before construction, first clean the loose dust and oil stains on the base layer thoroughly to ensure it is flat and dry. Otherwise, the panels will not adhere firmly, which will affect the usage effect.  When cutting the boards, use special tools to avoid chipping the edges. After cutting, clean up the burrs on the edges. This way, they will fit together more tightly without leaving any gaps.  When fixing the boards, the spacing of the screws should be appropriate. Don't make it too wide, otherwise the force will be uneven and problems may occur. Also, don't let the screws be exposed outside to rust, as it will affect the service life of the boards.  Having been in this business for so long, I always believe that a good backing plate should be able to solve practical problems for everyone and avoid repeated repairs. The LONGER Professional XPS Backing Plate has been optimized many times, with guaranteed quality, no formaldehyde, and meeting environmental protection requirements. Whether it's commercial buildings, home decoration, or municipal projects, you can use it with confidence. It can help solve problems such as water leakage, deformation, and construction difficulties, and also save costs and improve efficiency. This is also the reason why many customers choose it.

Hello everyone, I'm the technical consultant of Longer. When chatting with suppliers and construction workers, people often ask: "Is there a special size of XPS backing board available?" "For outdoor terraces, can we get a more waterproof one?" In many project scenarios, standard boards simply don't work, and using them haphazardly will only cause trouble. Today, I'll open up and tell you the truth, when you need customization and how to customize in Longer. Whether it's for export, outdoor use, or basements, I'll explain everything clearly to you.   I.Don't force yourself to choose the standard board. Customization is much more convenient.  Not all tasks need to be customized. But in these cases, choosing standard boards would be a complete waste of time and money; customization is the right approach.  1.The size is special. Cutting the standard board causes pain.  For instance, when renovating old houses or decorating irregular spaces, the dimensions of the walls and floors are quite strange. The standard 4x8-foot boards are wasted after being cut in half, and they have to be pieced together repeatedly, resulting in extremely low construction efficiency. Some commercial projects have specific designs, requiring boards of specific lengths and widths. Customization can ensure a perfect fit, eliminating the need for unnecessary fuss.  2. In special situations, ordinary boards cannot withstand the pressure.  Like outdoor terraces, which are exposed to wind, sun, heat and cold alternations, ordinary boards won't last long before they deform; basement floors are damp and need to be insulated, and regular models simply can't handle it. At this point, custom-made solutions are necessary. The density and waterproofing level can be adjusted, perfectly fitting the scenario, and there's no need for rework later.  3. Export orders have their own specific rules  Exporting companies all know that the requirements for building materials vary from country to country. The EU demands environmental certification, while the US has specific requirements regarding measurement units. Standard boards often fail to meet these standards. Customized products can precisely match these requirements, and the packaging and labels can also be modified as needed. This way, the products can pass through customs smoothly without any issues.  II. In the case of Longer customization, all of these can be modified as per your requirements.  Many people think that customization just involves changing the size. But there's much more to it. From size to performance, from appearance to export compatibility, everything can be adjusted according to your needs.  1.Size and thickness: Make it as large as you want!  In terms of size, whether it's a large board that is larger than 4x8 feet or a small irregular board, as long as you provide a drawing, we can make it. The thickness can be flexible, ranging from 6mm to over 20mm. For example, if the basement requires a thicker insulation layer, 25mm or 30mm can be arranged. The load-bearing and insulation can be completed in one step.  2. Density performance: Enhanced for greater durability  For outdoor and industrial environments that require durability, a high-density option should be chosen; for indoor construction that aims for lightness, the density should be adjusted to a moderate level. Additional benefits can be added for waterproofing and insulation. Shower areas need high waterproofing, and areas in cold regions need strong insulation. These features can meet the requirements and are more suitable than standard panels.  3. Branding: Adhere to your own logo, which is more professional.  If we go for a private brand, we can print your logo and specifications on the board, making it look professional and enhancing the recognizability. We can also customize the packaging. For export, we can provide wooden packaging and moisture-proof packaging as required. We will handle all of this for you.  4. Export Compliance: Assist You in Adhering to Regulations in All Countries  To produce custom XPS tile backboards, we first need to understand the regulations of the target country. We will meet all the environmental protection and fire prevention standards. The unit labels and the language of the instructions will also be in accordance with the local requirements. We won't be rejected due to non-compliance.  III. Customization is just three steps away, simple and without hassle.  Don't think customizing is troublesome or that coordinating back and forth is tiring. Just three simple steps and you'll easily get the product you want.  Step 1: Clearly articulate the requirements, and the more detailed, the better.  Tell us clearly what it is for (outdoor, basement or exit), what the dimensions are (length, width, height), and what effect is needed (waterproofing, insulation). If you have the drawings, please send them directly. This will be more accurate. For example, if you say "An outdoor board for exporting to the United States, 3x6 feet, resistant to low temperatures", we can immediately come up with a solution.  Step 2: We will propose a plan and first produce samples for verification.  We have received your request. We will provide you with the solution within 1-2 working days, including parameters, quotations and delivery time. If you are not sure, we can first make a small sample for you to review. Once you are satisfied with the appearance and performance, we will proceed with mass production to avoid any problems with large-scale production.  Step 3: Confirm the order and wait for delivery.  The samples are fine. Once we sign the contract and you pay the deposit, we will start the production. During the production process, we will keep you informed of the progress in real time. If there are any issues, we can make changes at any time. Once the products are ready, whether it's domestic delivery or export customs declaration, we will handle everything for you throughout the process.  IV. Two real cases for your reference  Let me show you two custom orders we have done. See if any of them resemble your project.  Case 1: Outdoor Terrace Customization Edition  A client wanted to build a terrace for their villa. It needed to be resistant to both heat and cold, have strong waterproofing properties, and be of irregular dimensions. We made a 20mm thick high-density board for him, which enhanced the waterproofing performance. The size precisely matched the shape of the terrace. It has been used for over two years and has not deformed or leaked water. The client was extremely satisfied.  Case 2: Customized Products for Export to Europe  A foreign trade boss wanted to export to Europe and ensure compliance with the EU environmental standards. The packaging had to be in millimeter units and be moisture-proof. We adjusted the formula according to European regulations, determined the dimensions, and also prepared an English manual and certifications. The goods passed the customs inspection smoothly without any hitches.  V. Frequently Asked Questions, Helping You Avoid Pitfalls  How many units should be ordered for the customization?  There is no mandatory requirement. Both small batch samples and large quantity purchases can be accepted. The larger the quantity, the more cost-effective the unit price will be. Just communicate with the sales department for details.  2. How much longer does customization take compared to the standard board?  It usually takes 3 to 5 days, depending on the complexity. Just changing the size is quick; but if we need to optimize the performance and adapt to the export requirements, it will take a bit longer. We will clearly inform you of the delivery time in advance, so it won't affect your work.  3. Can custom-made items be returned?  Since it is a custom-made product, if the design you confirm doesn't match the original plan (such as different dimensions or performance), we will redo or adjust it for free. If you change your requirements yourself, we will also try our best to optimize it for you and minimize the losses.  Finally, let me say something truly honest.  Customizing XPS backing panels, the key lies in choosing the right manufacturer. Avoid those who only use templates; they are prone to problems later on. Longer has been in this business for over a decade. They are experienced in custom work for outdoor, basements, and export projects, and can accurately meet your needs.  If you have any customization ideas, whether it's regarding size, performance or export, feel free to talk to us. No empty promises here. Just follow your requirements and you'll save yourself a lot of trouble and get the suitable product.  

    Having been in this business for over a decade, I have supplied insulation materials to customers in Europe and the Middle East, but I have also fallen into countless traps. The most frustrating one was the XPS insulation board - it was all very impressive, but when delivered to the construction site, it either lacked strength or had falsely marked thermal conductivity. Last year, I received a contract from a German client who required a thermal resistance value of R-10 or above. I sent samples of a well-known brand for testing and all passed. However, when the bulk goods arrived at the port for testing, the result was only R-7.5. In the end, I had to pay the freight and replenish the goods. The client directly kicked me off the supplier list. Who wouldn't be furious about this?  Later, I summarized that the main problems in the industry were three: Firstly, there was false performance labeling. The manufacturers used laboratory data to deceive customers. Secondly, the dimensional stability was poor. The XPS boards delivered to the Middle East contracted and deformed, and the decorative lines simply didn't match the seams. Thirdly, the supply cycle was unpredictable. During peak seasons, the production schedule was set for two months, and the construction sites were constantly pressured to complete the work on time. The customers were even more frustrated - they were engaged in Interior Decorative Wall Panel Products, and the wall decoration needed to be constructed together with the insulation layer. If the board deformed, the EPS Decorative Moldings would crack, and the entire wall would have to be scraped off and rebuilt. The owner of the decoration company complained to me, saying that using your company's boards, they had to redo the work three times, and the workers' wages were even higher than the cost of the materials.  So now I'm really focusing on LONGER. Their XPS insulation board is truly capable of being used for low-temperature cold storage facilities - with a closed-cell rate of over 98%, moisture can't penetrate. We supplied a batch to a Norwegian client, which was used on the exterior wall of a cold storage at minus 20 degrees Celsius. For three years, not a single bulge has appeared. Moreover, the compression shear strength reaches 0.12 MPa, which is 30% higher than the national standard. Even if you kick it with your foot, it won't break. What's more crucial is that they combine this with EPS Insulation Board to make composite decorative panels. The surface is directly hot-pressed with an engineered wood board, saving the construction team three processes - laying a base layer, hanging mesh, and plastering. The construction period is reduced by half. An engineering contractor in Dubai calculated that using LONGER's XPS board for the exterior walls of a villa results in a combined cost that is 40% lower than using ordinary extruded polystyrene board combined with stone dry hanging, and it also provides an additional layer of insulation.  In the end, the value of XPS insulation board lies in two aspects: it helps save energy and provides insulation in summer, and prevents moisture and prevents mold in winter. It is the most cost-effective for use in basement of villas, exterior walls of cold storage facilities, and steel structure roofs. When combined with their EPS Decorative Moldings (Roman column heads, window casing lines), it achieves a seamless integration of insulation and decoration, eliminating the labor cost of a separate construction process. Here are a few tips and product features:   Product Features  Low density but high compressive strength (35kg/m³ can achieve 0.15MPa), with a transportation damage rate of less than 0.2%. Flame-retardant B1 grade, self-extinguishing when away from fire, with a smoke density 60% lower than that of the same grade. Successfully passed the fire safety inspection in the Middle East on the first attempt. Purchase Tips  Don't just rely on the thermal conductivity. Ask the manufacturer to provide the measured value of the "water vapor permeability coefficient" - a value lower than 2 ng/Pa·m·s indicates true waterproofing. When shipping the entire cabinet by sea, have LONGER perform "tray vacuum coating" to ensure the humidity upon arrival at the port does not exceed 5%. Otherwise, the boards will absorb moisture at the construction site and then dry out, resulting in a shrinkage rate of up to 2%. Currently, all my Italian and Saudi clients have switched to LONGER. The return order rate is 100%. To put it simply, when dealing with overseas B2B wholesale, less is more - having a reliable XPS board supplier can save you 80% of customer complaints. Don't ask me how I know - I learned from the losses.

      I've been in the procurement business for over a decade. To be honest, I've encountered many problems with insulation materials. At the beginning, I was greedy for cheap prices and bought a batch of ordinary boards. However, when they were installed in a chemical plant project, problems emerged within half a year - they absorbed water and bulged. The insulation layer looked very wet, and the client complained all at once. Later, I also encountered a problem with the fire resistance test getting stuck. The party's inspection directly shook their head and said that it couldn't withstand the fire at all. During that period, just dealing with returns and compensation almost drove me into depression. In the end, the two things that really bothered me were: first, the waterproofing ability was poor. Over time, the insulation effect was directly reduced; second, the fire resistance grade was deceptive. Even with the "A grade" label, when tested, it turned out to be false.  Later, we switched to LONGER's rock wool board, and things finally stabilized. I mainly deal with overseas B-end wholesale, with customers distributed in Europe, America and Southeast Asia. The requirements are generally not low. We tried several brands, and the products of LONGER immediately showed a difference when used - uniform density, each block is compacted, and when cut, it doesn't break or become fluffy. The workers had less trouble cleaning up debris in the first month of installation. Of course, what I value most is its waterproofing property. When placed outdoors for a long time and exposed to so much rain, opening the package didn't absorb water. The water test was also satisfactory. There's no need to worry about fire resistance either. It has A1-level certification, which has been tested several times. The conclusion given by the laboratory was "non-combustible", without smoke or cracking. The factory took the report to the fire department for inspection and never encountered any problems.   By the way, the environmental aspect of LONGER is also quite interesting. Currently, overseas regions are conducting increasingly detailed checks on the source of materials. They have a recycling process where they incorporate the glass bottles, perfume bottles, penicillin bottles, and health product bottles that we commonly see into the raw materials, and then re-melt and stretch them to make fiber boards. This operation not only recycles the discarded bottles but also is cleaner and more durable than traditional slag fibers. When pitching a deal to foreigners, mentioning this point really works. They truly get it.  Product features, I have summarized them into three points:  Waterproof performance is excellent - hydrophobicity rate over 99%, and it retains insulation even when soaked and dried. Fireproof compliance is assured - A1 grade non-combustible, won't smoke even when heated to a certain temperature. Environmentally friendly materials - mixed with recycled glass bottles, perfume bottles, penicillin bottles, and health product bottles from waste, which can add points in the review report. As for experience, there are two points:  ① Ask the manufacturer to send samples. Take a spray bottle and spray it for a few seconds. See if the water droplets roll off. If they don't stick together, don't buy it. ② Don't just look at the thickness. The bulk density is more important. The 120kg/m³ boards from LONGER serve as the base, and their load-bearing effect is better than that of the 150kg boards from other brands.  Doing wholesale business is essentially about helping customers save time. The LONGER brand has a good reputation among overseas users. Over the years of our cooperation, we have rarely dealt with any after-sales issues. The quality of the materials ultimately determines whether customers will place repeat orders. To be honest with you: Those boards that keep breaking down frequently - no matter how much commission we earn, we don't feel at ease. Later, we changed to a better product, which was more reliable and made customers feel more secure.  

The core difference between XPS waterproof backboard and cement backboard   Comparison Dimension XPS Waterproof Backing Board Cement Waterproof Backing Board Waterproof & Moisture Resistance Closed-cell structure, 100% moisture-proof, no water absorption or expansion. It can maintain stable performance in humid environments for a long time without mold or rot. Requires additional waterproofing treatment. The cement material itself is prone to water absorption, which may lead to mold growth and structural damage over time if not properly treated. Weight & Installation Lightweight, easy to carry and cut. A single person can complete the installation operation, which greatly saves labor costs and shortens the construction period. Heavy and bulky, requiring multiple people to cooperate during transportation and installation. Cutting is difficult and requires professional tools, which increases the difficulty and cost of construction. Load-bearing & Durability High rigidity, strong compression and impact resistance, not easy to crack or deform. It has excellent weather resistance and can maintain stable performance in harsh environments such as high temperature, low temperature and humidity. Ultra-high load-bearing capacity, but brittle and easy to crack if subjected to impact during construction or use. It is also prone to aging and chalking when exposed to the outdoor environment for a long time. Construction Cost Higher efficiency in installation, lower labor costs, and no need for additional waterproofing materials, so the overall construction cost is more economical. Longer construction cycle, higher labor costs, and additional investment in waterproofing materials and processes, resulting in higher overall construction costs. Applicable Scenarios Suitable for all-scene waterproof projects, including wall cladding, flooring, roofing, bathrooms, basements and other indoor and outdoor construction scenarios. Only suitable for ultra-heavy load scenarios, such as industrial floors, outdoor high-load ground and other special construction projects that do not require frequent maintenance.         Why Moisture-Resistant XPS Backing Boards Are Suitable for Most Projects No Additional Waterproofing Required - Save Time and Money As a professional supplier of XPS waterproof backboards, Longer is well aware that for most construction projects, time and cost control are of paramount importance. Unlike cement backboards that require additional waterproof coatings and membrane applications, our moisture-proof XPS backboards, with their closed-cell extruded structure, inherently possess waterproof properties. From the moment of installation, they form a reliable waterproof barrier, eliminating the need for complex additional waterproofing procedures. This not only reduces the construction period by an average of 30% but also saves on waterproofing materials and labor costs, helping you maximize the project's benefits. Long-lasting, not moldy or rotten. One of the most troublesome problems in construction projects is the mold and rot of building materials caused by dampness, which not only affects the appearance of the project but also reduces the structural safety and service life. Our moisture-proof XPS backboard has completely solved this problem. Its closed-cell structure does not absorb water at all, and it is not easy to breed mold and bacteria even in long-term damp environments such as bathrooms and basements. After years of use, it can still maintain its original performance and appearance, eliminating the trouble and cost of later maintenance and replacement. This is an advantage that no matter how perfect the additional waterproof treatment of cement backboards is, it cannot compare with. When to choose cement backer board instead of XPS waterproof backer board? High-load-bearing scenarios, such as the floors of industrial plants Although our XPS waterproof backboard has excellent load-bearing capacity, it still cannot match the cement backboard in scenarios with extremely high load requirements. For instance, in industrial plants and warehouses where heavy equipment and large amounts of goods need to be supported, the cement backboard would be a more suitable choice. Its extremely high load-bearing capacity can meet the special demands of such projects and ensure the stability and safety of the ground structure. Extreme high-temperature environment In extremely high-temperature environments (such as areas near high-temperature equipment in industrial workshops), the high-temperature resistance of XPS waterproof backboards will be somewhat affected. In such cases, cement backboards with better high-temperature resistance are more suitable. They can maintain structural stability in high-temperature conditions and prevent deformation and damage caused by high temperatures. However, it should be noted that even when choosing cement backboards in such scenarios, additional waterproofing treatment must be done to prevent damage from moisture. Longer XPS waterproof backboard: The better choice for 90% of construction projects How does our XPS backboard solve the limitations of cement backboards? After years of research and development, Longer's XPS waterproof backboard has comprehensively addressed the pain points of cement backboards in practical applications. In response to the need for additional waterproofing of cement backboards, our XPS backboard, with its advanced extruded closed-cell technology, achieves 100% waterproof performance, eliminating the need for additional waterproofing measures. Regarding the heavy weight and difficult installation of cement backboards, our XPS backboard is lightweight and easy to cut, significantly improving construction efficiency and reducing labor costs. In addition, to address the issue of mold and rot in cement backboards, our XPS backboard is moisture-proof and mold-resistant, with a long service life and no need for frequent maintenance.

  With over a decade in procurement, I've handled hundreds of construction materials. In recent years, EPS cement walls have gained popularity in overseas projects—but honestly, I’ve encountered many issues along the way. Colleagues often ask me right away:   Why do EPS wall panels at construction sites frequently develop cracked joints? Why do boards warp halfway through delivery? Why do quotes seem cheap, only to end up more expensive when factoring in waste and rework costs? The root causes are simple: substandard material density, uneven cement layer thickness, and poorly compacted EPS beads in the core. For clients, it’s even worse—project delays go without saying, and they also face complaints from project owners.    My solution at the time was simple: I directly approached Longer, a leading domestic manufacturer. Their approach to solving the problem was equally clear—focusing relentlessly on raw materials and manufacturing processes, replacing traditional manual casting with fully automated production lines. The result? In my Middle Eastern hotel project last year, we used Longer's EPS Cement Wall covering 5,000 square meters. Installers reported clean cuts and perfectly flat installation. Over a year later, not a single crack has appeared. Moreover, due to its lightweight nature, the structural load on the steel frame is significantly reduced. The client even sent an email specifically praising, "Finally, I don't have to keep running to the site to supervise repairs anymore."  Let's talk about product value. This EPS Cement Wall is primarily used for partition walls and insulated exterior walls, especially suitable for overseas steel-structured buildings. It reduces construction time by three times compared to traditional aerated blocks and allows direct nailing or hanging of heavy objects without the need for pre-installed studs. Several construction teams I've worked with long-term now exclusively specify Longer products because they've found that the boards have a low breakage rate during transportation—every bit saved translates into profit.    Speaking of this, let me briefly mention two other products in our portfolio: SPC Flooring and PVC Wall Panels. Many overseas B2B customers tend to purchase all three together—using PVC Wall Panels for waterproofing bathroom walls, installing SPC Flooring on the floor for durability, and employing EPS Cement Walls for insulation and soundproofing in partition walls. These three Longer products work well together, making warehouse handling convenient. I often tell new clients: if you want to save time and effort, just order all three in one container, and I can even label the unloading sequence for you.    Product Features:    High Crack Resistance: EPS granules are pre-expanded and compressed into shape with cement mortar in one step, resulting in minimal internal stress and no cracking throughout the entire panel.   Precise Dimensions: Length and width tolerances are controlled within 1mm, with on-site cutting waste below 2%, saving labor.   Fireproof Class A: The core layer is self-extinguishing EPS, covered by a 15mm thick cement surface layer that extinguishes automatically when removed from flame, passing British standard fire tests.     Tips: ① For bulk orders, always request manufacturers to arrange panels according to container dimensions. Longer provides free container layout diagrams, reducing shipping costs by over 10%. ② For overseas construction, pay attention to adhesive selection: ordinary white cement mixed with glue tends to peel off; we recommend using specialized two-component bonding mortar—Longer offers free formulation support.    Simply put, in procurement you need to spend money where it counts. Over the years, I've tried other brands, but when it comes to consistent quality control and after-sales support, Longer has never let me down. If you're stocking up for overseas construction sites, I recommend directly requesting their latest test reports and project references—this way you can avoid the hassle of factory inspections yourself.

Whether for household use or for construction projects, customers all say it is durable and attractive. The reputation is truly solid!"    

  I have been engaged in building materials procurement for over a decade, and the product that causes me the most headache is XPS backer board. The industry's pain points are obvious: ordinary materials tend to mold and deform in humid environments. If the density of XPS bathroom backer board is uneven, it is prone to cracking. Moreover, the insulation performance of XPS thermal insulation board is often unstable. These problems have caused us wholesalers a lot of trouble - there are continuous complaints from overseas customers, high return rates, and often additional compensation for construction losses, leaving us with no profit left. However, since we started promoting the Longer XPS series, the situation has completely reversed. What we provide is a one-stop solution: from the base layer of the wall to the bathroom-specific solution, and then to the entire house insulation, covering all aspects. The actual effect is very obvious: customers report that after installation, the wall is flat and does not crack, the bathroom is free from mold stains again, the insulation performance has been measured to meet the standards, the project has passed the acceptance inspection for the first time, and our wholesale orders have become increasingly stable.  The core value of this product lies in making wholesale purchasing simple and reliable. In terms of application, XPS backer board is suitable for interior wall panels, XPS bathroom backer board is dedicated to wet areas, and XPS thermal insulation board is used for exterior wall insulation systems. For us as wholesalers, this means that with a stable and reliable product line, we can meet the diverse needs of customers, reduce inventory pressure, and enhance reputation.  Based on my experience of handling countless orders over the years, I have summarized several key features and practical suggestions for your reference, fellow professionals:  Product Features:  Moisture-proof and mold-resistant core: The XPS bathroom backing board from Longer incorporates a moisture-proof core layer, ensuring stable performance in humid environments and significantly reducing post-sale issues. High strength and stability: The XPS backing board has uniform density and excellent compressive strength. After installation, the wall is less likely to deform, providing a solid foundation for subsequent tile installation or decoration. Thermal insulation and energy conservation: The XPS thermal insulation board has a low and stable thermal conductivity, helping end customers effectively improve the energy efficiency of the building. Tips for procurement and use:  Batch inspection: When purchasing in large quantities, it is essential to conduct random checks on the density of the panels and the flatness of the edges. This is the first step to ensure the quality of the construction. Adaptation suggestion: When recommending to customers, clearly distinguish between ordinary areas and bathroom wet areas. Use corresponding panels for matching, which can effectively enhance the project value and our professionalism. Storage instructions: The panels should be stacked flat in a dry environment and avoid direct sunlight. With just one simple step, they can be kept in the best condition at the time of delivery. In summary, choosing Longer means choosing peace of mind. It is not just a product; it is also a quality endorsement from our wholesalers for expanding overseas markets. If you have specific project requirements for solutions? Feel free to discuss at any time.

The Middle East is characterized by high temperatures, dryness, and dense buildings. The fire protection standards for building insulation materials are strict (such as Saudi Arabia's SBC801 and the UAE's NFPA system). Ordinary insulation materials often fail to meet fire protection standards, leading to project delays and difficulties in acceptance, and there is also a risk of fire spread. This not only increases the cost of rework but also poses a threat to building safety. To address this issue, Longer, a professional Rock wool board manufacturer, has launched a full range of products including Rockwool board 1200x600mm, Rockwool slab, and Stone wool board, which strictly comply with Middle East fire protection standards and provide A-class non-combustible insulation solutions. These products are widely used in external wall insulation, roof insulation, and fire isolation strips, meeting compliance requirements while achieving efficient insulation, facilitating the smooth implementation of Middle East construction projects.   Longer's rock wool series is made from natural basalt and processed through high-temperature melting and fiberization.

  During the EIFS/ETICS exterior wall insulation construction in buildings, there are common problems such as water seepage, insulation performance decline, and anchor loosening. These not only increase the construction rework costs but also shorten the insulation service life of the building and affect the efficiency of project acceptance. To address these issues, Longer has launched a solution of XPS insulation backing plate and Nylon Anchor Plate, which is compatible with EIFS/ETICS system construction and provides wholesale thermal break backing plates for construction services. This can not only strengthen the insulation defense line and eliminate the water seepage隐患， but also enhance the anchoring stability， reduce construction losses， and provide efficient and durable core support for building insulation projects. It is widely used in various scenarios such as exterior wall insulation of buildings， floor heating base laying， etc.， achieving integration of insulation， waterproofing， and anchoring， and helping to improve project quality and efficiency. Longer XPS insulation backing plate uses high-density XPS extruded material. The closed-cell foam structure effectively blocks water vapor penetration. Combined with the dedicated Nylon Anchor Plate， it is compatible with the mechanical anchoring requirements of the EIFS/ETICS system， avoiding the detachment and falling off of the insulation layer. The product combines insulation and load-bearing performance， can directly be used as the base layer for tiles and decorative surfaces, without the need for additional protective boards， simplifying the construction process， and reducing material and labor costs. Bulk purchasing offers better cost-effectiveness and is suitable for various new construction projects， old community renovation projects， and other insulation renovation scenarios.  Product Features  1.High adaptability: The XPS insulation backing plate perfectly matches the EIFS/ETICS system with the Nylon Anchor Plate. At the same time, it can meet the demand for wholesale thermal break backing plates for construction, and is suitable for various construction scenarios.  2. Stable performance: The XPS material has a low water absorption rate, strong compressive strength, and can withstand both high and low temperatures. It eliminates the problems of freeze-thaw cracking and water seepage, and maintains a long-lasting and stable insulation effect. The nylon anchor plates are easy to install and provide firm anchoring, preventing the insulation layer from loosening or falling off.  3. High cost-effectiveness: Integrated design for complete equipment, simplifies construction processes, reduces material waste, and offers exclusive discounts for bulk purchases. This approach balances both project quality and cost control.  Tips  1.During the construction process, it is necessary to ensure that the XPS insulation backing plate is laid flat and the seams are tightly connected. Special sealant can be used for sealing to enhance the waterproof and thermal insulation performance.  2. When installing the Nylon Anchor Plate, the depth of anchoring must be controlled to avoid looseness due to insufficient depth. The installation force should be adjusted according to the different base materials to ensure a firm anchorage.  Longer has always focused on the pain points in building insulation construction. With high-quality products and the advantage of large-scale supply, it provides construction parties and purchasing parties with worry-free and efficient solutions, helping building insulation projects meet the standards for acceptance and achieving long-term energy conservation.
