When it comes to durable, trouble-free tiling—whether for residential renovations, commercial construction projects, or specialized applications—China Feininger XPS Tile Backer Board stands out as the all-in-one substrate that addresses the key drawbacks of traditional tiling materials. As a flagship product of China Feininger, a professional manufacturer specializing in new building materials with advanced production capabilities and strict quality oversight, our XPS Tile Backer Board is crafted using high-grade materials and state-of-the-art automated production lines. It has become the preferred choice for professional contractors, building suppliers, and DIY enthusiasts who prioritize reliability, efficiency, and long-term performance.

Boasting a premium five-layer structure, our XPS Foam Tile Backer Board is manufactured in strict accordance with ISO9001 quality management standards. It consists of two outer layers of polymer mortar, two middle layers of reinforced fiberglass mesh, and a high-density closed-cell extruded polystyrene (XPS) core at its center. This innovative structure differentiates our product from the competition, integrating 100% waterproof protection to fend off moisture damage, lightweight convenience to simplify installation processes, and excellent thermal insulation to boost energy efficiency—all within a single, easy-to-manage panel that eliminates the need for additional materials or complicated pre-installation preparation.

100% Waterproof & Mold-Resistant:

The closed-cell XPS core features an outstanding closed-cell rate of 90% or higher, with key parameters detailed in the product specification table below. Unlike conventional cement boards that require an extra waterproofing membrane (which adds both time and expense), our XPS backer board is inherently waterproof, with no water penetration from the inner side of the reinforcement layer (passing impermeability tests). It effectively blocks water intrusion, preventing mold growth (Grade 0, no mold detected in tests), making it an ideal option for moisture-prone areas such as showers, wet rooms, basements, swimming pools, and laundry rooms. Additionally, it ensures structural stability by minimizing moisture-induced deformation.

Our XPS Tile Backer Board is extremely lightweight, with weight varying based on thickness (see the detailed table below)—up to 75% lighter than standard cement boards (which weigh 8-10 pounds per square foot). This lightweight design eases physical strain on workers, simplifies transportation, and facilitates maneuvering in tight spaces (such as small bathrooms or high-rise buildings), reducing installation time by up to 40%. Unlike cement boards, which require power tools and generate messy dust, our XPS board can be easily cut with a standard utility knife, enabling precise, clean cuts without the need for specialized equipment. Installation Guidelines: For solid walls, mechanical fixing requires a minimum board thickness of 10mm; for stud walls, space studs 600mm apart for boards 20mm and thicker, and 300mm apart for 10mm/12mm boards. Utilizing long or extra-wide panels can reduce the need for noggings and taping, further streamlining the installation process and saving both time and labor costs.

Our XPS Tile Backer Board delivers exceptional thermal insulation performance, with thermal conductivity parameters specified in the table below. Acting as a continuous insulation layer behind tiles, it reduces heat loss through walls and floors, prevents cold bridges (which cause condensation and energy waste), and enhances overall energy efficiency in both residential and commercial buildings. It also offers noise reduction capabilities, with a weighted normalized impact sound pressure class of ≤55 dB. This feature is particularly advantageous for projects with underfloor heating systems, as it ensures heat radiates upward into the room (rather than being lost downward into the subfloor), lowering energy consumption and improving occupant comfort. We also provide pre-grooved XPS backer boards specifically designed for underfloor heating, optimized for maximum efficiency and minimal impact on floor height.

Despite its lightweight design, our XPS Tile Backer Board is built for durability. Key strength parameters (including core density, compressive strength, and shear strength) are detailed in the product specification table. The dual-layer reinforced fiberglass mesh, combined with a smooth polymer cement coating, creates a strong, rigid surface capable of supporting heavy tiles (such as ceramic, porcelain, and natural stone) without deflection or warping. This structure also absorbs stress from thermal expansion and contraction, reducing the tile hollowing rate from 15% (common with traditional materials) to less than 3%. The polymer cement coating provides an optimal surface for tile adhesives, ensuring a secure, long-lasting bond that prevents tile detachment or cracking. The board also exhibits excellent impact resistance, withstanding 10 or more impacts without damage.

Our XPS Tile Backer Board is designed to accommodate a wide range of tiling scenarios, making it suitable for both residential and commercial projects. It can be used on walls, floors, countertops, shower enclosures, exterior walls, and even specialized areas like pool surrounds. We offer flexible customization options to meet the unique needs of your project: thickness ranges from 4mm to 80mm, with standard sizes available in both metric and imperial units (see the detailed size table below). We also provide special-shaped boards (including L-shaped, U-shaped, and bath cladding boards), as well as prefabricated shower niches and shower trays (with a minimum 2% drain angle) to cater to diverse project requirements. The product is compatible with all standard tiling tools, adhesives, and grouts, making it a universal solution for all types of tiling projects. ODM and OEM orders are also welcome to meet your specific branding and product needs.
