Moisture Resistant Tile Backer Board

This Moisture Resistant Tile Backer Board is crafted using an integrated composite process. Its core is made of high-density extruded polystyrene (XPS) board, reinforced with alkali-resistant high-strength fibers on both the top and bottom layers. The surface is coated with a special nano-quartz protective coating. The entire structure is prefabricated in the factory, resulting in a robust and highly integrated design. Specifically optimized for humid environments, the board absorbs less than 1% of water after 96 hours of continuous immersion. Combined with its dense surface coating, moisture has difficulty penetrating the board's interior. Even when used long-term in high-humidity areas such as shower areas, bathrooms, and basements, it effectively isolates moisture, preventing dampness and mold growth on walls and providing long-term protection for the building's foundation.

Many people worry about the load-bearing and bonding capabilities of lightweight boards, but this product completely eliminates these concerns. Actual measurements show that the board's average bending strength reaches 3900KPa, demonstrating excellent impact and deformation resistance, and it won't dent or bend under daily stress. The board surface is perfectly compatible with mainstream tile adhesives and bonding mortars on the market, achieving a bonding tensile strength of up to 0.4MPA, ensuring a strong bond for ordinary tiles, slabs, natural stone, or mosaics. It also features a practical design that buffers minor stresses generated by the wall structure, mitigating the effects of slight building vibrations and wall deformation, effectively preventing tile cracking and detachment, and significantly extending the overall lifespan of the renovation.

In addition to its core moisture-proof tiling function, this Moisture Resistant Tile Backer Board also provides insulation and soundproofing. With a thermal conductivity of only 0.034 W/(m·K), the sealed internal structure effectively blocks the transfer of hot and cold air, preventing outdoor heat waves in summer and locking in indoor temperature in winter, thus helping to reduce energy consumption of heating and cooling equipment. The commonly used 12mm sheet provides up to 23dB of sound insulation, significantly reducing noise transmission when used for mezzanine floors, interior partitions, and pipe enclosures, creating a quieter living and working environment. Safety is also guaranteed; the sheet meets the B1 flame-retardant standard, slowing the spread of flames.

Its advantages are particularly prominent in on-site construction. The sheet has a uniform texture, and the cutting process generates almost no dust, resulting in a cleaner construction site. A single sheet can simultaneously serve as a leveling layer, waterproof layer, and insulation layer, eliminating the cumbersome procedures of traditional construction such as wire mesh, multiple layers of plastering, and repeated waterproofing applications, shortening the construction cycle and effectively controlling labor costs. The sheet exhibits excellent dimensional stability, with extremely low deformation rate under high temperature and humidity conditions, eliminating the need for expansion joints during installation.

The product comes in various thicknesses to suit different scenarios: 6mm boards are primarily used for wardrobe moisture protection and simple tile base layers; 12mm is a universal choice for kitchen and bathroom walls and light steel keel base layers; 20mm is suitable for quickly leveling uneven walls and pipe wrapping; 30-40mm is mainly used for roof and exterior wall insulation and basement moisture protection; 50mm thicker boards can also be used to directly build lightweight partitions and shower enclosures.

Its applications are extremely broad, ranging from whole-house renovations and complete kitchen and bathroom upgrades to commercial projects such as exterior wall insulation, roof waterproofing, steel structure engineering, and ventilation duct construction. It can handle all these tasks, making it a superior upgrade option from traditional base layer boards.
