Say goodbye to dampness and hollowing! LONGER XPS backing board, the reliable choice for overseas building material suppliers.

2026 04/28

 

In the overseas building materials market, many buyers often encounter problems such as hollowing after tile installation, dampness and mold on the wall, and deformation of the insulation layer due to pressure difference. These issues not only lead to more rework, longer construction periods, and increased customer complaints, but also result in high after sale costs, especially in humid areas and under floor heating projects. To address these problems, LONGER has launched a high-quality XPS insulation backing board (Extruded polystyrene backing panel) as a core product in the building materials sector. It can solve problems such as waterproofing, insulation, pressure resistance, and mold prevention in one go, making the construction process simpler, the project more durable, and the cost more controllable.

LONGER (Xuzhou Langge New Materials) is a powerful factory integrating R&D, production, and sales. Relying on the industrial advantages of Xuzhou, Jiangsu Province, it focuses on providing stable and reliable insulation and decorative boards for global customers. With excellent quality, reasonable prices, and professional services, it has won the long-term trust of overseas customers on the national standard information public service platform. The XPS backing board of LONGER adopts advanced extrusion technology, with a closed-cell rate of over 99%. This fundamentally solves the problems of traditional boards absorbing moisture and deforming in humid environments, as well as insulation failure. It is the ideal base material for bathrooms, kitchens, floor heating, exterior walls, and underground spaces.

Product features (serial numbers marked)

Waterproof and moisture-proof without absorbing water: The closed-cell structure hardly absorbs water, and it does not mold or powderize even in long-term humid environments, eliminating dampness and hollowing.

High pressure resistance without deformation:The compressive strength is ≥ 300KPa, capable of withstanding tiles and daily loads, and remaining stable in the floor heating environment for a long time.

Insulation, heat preservation, energy saving: The thermal conductivity is as low as 0.030W/(m・K), and thin boards can also achieve efficient insulation, reducing energy consumption.

Lightweight and easy installation, saving labor:Lightweight, directly cuttable, no need for complex tools, effectively shortening the construction period and reducing labor costs.

Size stability and durability: Resistant to aging and corrosion, less prone to deformation and cracking under temperature and humidity changes, extending the lifespan of the building.

Useful tips (serial numbers marked)

Suitable for multiple scenarios: Suitable for bathrooms, kitchens, swimming pools, floor heating, exterior wall insulation, and basement moisture prevention and other scenarios with moisture and insulation requirements.

Compatible with ordinary cement mortar:The surface can be directly laid with tile adhesive, no need for additional leveling layer, and the base treatment is simple.

Flexible batch customization: Can be customized according to common thicknesses (10–50mm) and sizes in overseas markets, suitable for different national construction standards.

The LONGER XPS backing board, as a cost-effective Building material, combines the four core values of waterproofing, insulation, pressure resistance, and mold prevention. It reduces rework and after-sales issues from the source, helping overseas B-end buyers improve project reputation and reduce overall costs. Our factory directly supplies and supports large-scale stable shipments, provides professional technical support and customization services, and helps global customers create green, energy-efficient, and reliable building projects.
