Built for Durability: Waterproof and Formaldehyde-Free Construction for Lasting Performance

Core Construction: Engineered Wood-Plastic Composite (WPC) Core
The structural integrity and moisture resistance originate from a high-density (≥ 1.25 g/cm³) WPC core. This engineered material combines thermally modified wood fibers with polymer matrices (predominantly PVC) at a controlled ratio, typically 60:40 (wood:PVC). This formulation eliminates the biological food source for mold and negates the hygroscopic swelling inherent to solid wood. The core is further stabilized with laminated veneer lumber (LVL) reinforcement in stile and rail sections, ensuring dimensional stability against warping or twisting under varying climatic conditions (RH 30%-90%).

Advanced Lamination: Waterproof Barriers & Surface Integrity
All wood-derived components are encased within a continuous, co-extruded PVC cladding layer, acting as a monolithic waterproof barrier. The bonding process utilizes polyurethane-based adhesives that are themselves 100% waterproof and formaldehyde-free. Critical performance data for the composite structure includes:

Performance Advantages for Architectural Specification

• Total Moisture Immunity: The sealed system achieves a moisture absorption rate of <0.5%, making it suitable for direct-installation in bathrooms, kitchens, and coastal properties without risk of delamination or decay.
• Guaranteed Indoor Air Quality: E0-grade emissions are certified across all composite materials, adhesives, and finishing coatings, supporting projects targeting LEED, BREEAM, or WELL Building certification.
• Enhanced Acoustic & Thermal Performance: The multi-density composite core and airtight sealing gaskets provide a sound reduction index (Rw) of up to 32 dB. The low thermal conductivity of the material contributes to a improved U-factor, aiding in building envelope efficiency.
• Structural Longevity: The combination of UV-stabilized PVC surfaces and anti-fungal additives within the WPC matrix ensures colorfastness and biological resistance, maintaining structural and aesthetic performance for decades with minimal maintenance.

Quality Assurance & Compliance
Manufacturing is governed under an ISO 9001:2015 certified quality management system. Every batch of raw material is tested for formaldehyde content and mechanical properties. Final products undergo rigorous batch testing for operational force, impact resistance (Shore D hardness > 75), and long-term cycle testing (>200,000 cycles) to validate durability claims for high-traffic commercial and residential applications.
