Those who are engaged in the wholesale of building insulation understand that the most annoying thing is encountering these troublesome issues: the materials absorb water quickly, and once they get damp, they start to mold and deform, and the insulation effect drops sharply; the construction is also troublesome, consuming a lot of labor and time, with a high rate of later repairs, and the money spent doesn't yield good results, directly affecting project delivery and payment. To address these pain points, Longer specially customized an XPS backing plate for overseas B-end buyers. It is combined with XPS Extruded Polystyrene Board, XPS Tile Backing Board, and EPS Cement Wall for one-stop solution to all problems. Whether it's internal or external wall insulation and heat preservation, floor heating insulation, or floor padding and roof insulation, it can perfectly fit and be fully compatible. Bulk purchasing has a high cost-performance ratio, helping you save time and earn money.
Our Longer XPS backing plate does not have any flashy gimmicks, but it has all solid advantages. Made by the extrusion process, the interior is filled with numerous closed cells, like a honeycomb, and water simply cannot penetrate, so there is no need to worry about mold and deformation; the insulation effect is reliable, with a very low thermal conductivity, whether for winter heat preservation or summer heat insulation, the effect remains stable without the need for repeated repairs; and it has strong compressive strength, even if it is placed or stepped on randomly during construction, it will not deform or crack, saving a lot of later repair efforts. As a wholesale exclusive product, we have sufficient production capacity, and bulk supply does not delay, no matter how much quantity you need, we can deliver on time, and it is compatible with overseas container transportation, fully meeting the engineering supply needs of B-end buyers.
