Tile Backer Boards

Superior Waterproof Performance and Strict Waterproof Testing

True whole‑panel waterproof performance is verified through standardized lab tests, rather than relying merely on surface paint coating. Premium‑grade tile backer boards shall achieve volumetric water absorption rate below 1% and closed‑cell ratio above 95%. Thanks to the closed‑cell XPS inner core, our tile backer board meets such high thresholds, stopping liquid water and water vapour from penetrating into wall and floor substrates. Unlike ordinary gypsum boards and wooden panels that rot, delaminate or breed mould under persistent dampness, our composite backer stays dimensionally stable in long‑term humid conditions, eliminating hidden moisture risks for kitchen wet zones, ground floors and exterior wall structures exposed to rain splash

Every production batch undergoes sampling waterproof performance inspection. Test items cover volumetric water absorption, long‑term immersion durability and vapour permeability. Only boards passing all waterproof‑related indexes are permitted for packaging and shipment. This rigorous testing system guarantees stable waterproof capability for large‑scale engineering jobs

Outstanding High‑Strength and Mechanical Properties

Sufficient compressive strength and flexural strength are critical for floor‑use scenarios. For flooring installation, compressive strength ≥ 250 kPa is required to secure load‑bearing capacity and avoid tile hollowing after completion. Though featuring lightweight design - around 70% lighter than traditional cement fibreboard, which lowers dead load for buildings and eases manual handling and site cutting - our tile backer maintains rigid overall structure and excellent mechanical performance

Its robust bearing capacity can support heavy finishing materials including marble, large‑format porcelain tiles and ultra‑thin sintered stone slabs. The roughened cement‑textured surface optimises physical bonding with tile adhesive and thin‑set mortar. It firmly locks finishing tiles in place, drastically lowering tile hollowing, tile detachment and costly construction rework. Whether laid as floor substrate or mounted on exterior wall frameworks, the panel can bear normal construction loads without deformation

Fire‑Safety Grade and Eco‑Friendly Performance

Fire resistance is one essential evaluation dimension for building substrate materials. Our tile backer board is available with Class B1 fire‑retardant grade options. Relevant fire reaction tests are completed in authorised laboratories to satisfy European and American building code requirements. Meanwhile, the product holds environmental qualification credentials including China Ten‑Rings Environmental Labelling Certification. Zero formaldehyde release and halogen‑free raw materials ensure safe indoor deployment for kitchens and living areas

!!!Important note: this tile backing board shall NOT be applied to locations with open flames or continuous high‑temperature exposure such as stove inner walls. Material selection should match real‑world construction surroundings for maximised long‑term project stability

We supply a comprehensive size portfolio to fit diverse project requirements.

Thickness range： 6 mm‑50 mm for selection

Standard dimensions： 1200 × 600 mm, 2440 × 1220 mm (4ft×8ft), 2500 × 600 mm and other mainstream overseas specifications

Custom service： Custom‑cut dimensions, special thickness and surface treatment are acceptable per customer drawings or project specs

Beyond well‑known shower‑room wet zones, this tile backer board performs excellently for kitchens, ground flooring and exterior wall tiling works

Kitchen Areas

Ideal substrate for kitchen splash‑backs, counter‑top underlay and kitchen floor tiling. It copes with frequent water splashes, steam and cooking‑area humidity; prevents mould‑infested wall decay behind kitchen tiles. It fits both private home kitchen renovation and commercial restaurant kitchen refurbishment

Floor Substrate

Suitable for residential room floors, hotel public‑area floors, swimming‑pool surrounding floors. High compressive strength avoids subsidence and tile hollowing. It is compatible with under‑floor heating layouts. Light weight reduces overall building load for multi‑storey buildings

Exterior Wall Tiling Projects

 Works as backing substrate for external wall tile cladding. It delivers waterproof, moisture‑proof and thermal‑insulating benefits, defending external building walls against rain penetration and temperature fluctuation. It is widely adopted in commercial building facades and villa exterior renovation

Additional applicable cases include balcony tiling, basement moisture‑proof substrate, public bathhouses and other wet‑condition renovation & new‑build works

Factory Strength, Quality Control and Custom Solutions

Manufactured at our large‑scale intelligent manufacturing base equipped with full‑automatic production lines, the whole workflow, from raw‑material compounding, board forming, cutting, sampling lab testing to finished‑goods packaging, is strictly controlled. Real‑site factory workshop and plant overview photos can be offered for your reference during business communication

Each batch is sampled for multi‑item lab tests: water‑absorption testing, compressive strength test, flexural strength inspection and thermal‑cycling durability assessment. Model identification can be printed on board surfaces, convenient for on‑site stock management and project acceptance. Finished goods are wrapped by moisture‑proof protective film plus heavy‑duty cartons, offering reliable protection during long‑distance ocean freight to Europe, America and other international destinations. Complete certification documents and test reports are supplied together with shipments to support overseas customs clearance and local project inspection

Standard‑spec boards are kept in stock for fast delivery of small sample orders as well as bulk orders of tens of thousands square meters. We support custom‑cut sizes, special thickness and tailored technical performance according to project drawings

With trustworthy performance, flexible construction process and wide environmental adaptability, our Tile Backer Boards have become mainstream preferred base materials for decoration and infrastructure projects globally. We sincerely invite building‑material distributors, general contractors and engineering clients worldwide to discuss win‑win cooperation
