Understanding Hollow WPC Decking


What Is Hollow WPC Flooring?


Hollow WPC Flooring is an innovative twist on traditional WPC decking, featuring a lightweight yet sturdy hollow core that balances strength, insulation, and practicality. Our LWD-TF005 Terrace WPC Decking is engineered for terraces, combining natural wood aesthetics with the structural advantages of a hollow profile—enhanced sound absorption, easier handling, and reduced weight for elevated spaces.


The Value of Eco-Friendly Wood Plastic Decking


Terraces demand flooring that can handle foot traffic, weather changes, and environmental stress while staying sustainable. Eco-friendly WPC Decking meets these needs by using recycled materials, avoiding toxic chemicals, and offering long-term durability that cuts down on replacements. This flooring stands out as a responsible choice for modern spaces.


Sustainable WPC Hollow Terrace Decking


Material & Craftsmanship


Sustainable Sourcing


Each plank of LWD-TF005 Hollow WPC Flooring is made from recycled HDPE, natural wood fiber, and food-grade additives. We prioritize eco-conscious manufacturing, using 100% recyclable components and lead-free formulas to ensure safety for people and the planet.


Precision Hollow-Core Engineering


Using state-of-the-art extrusion technology, we create the hollow core structure that defines Terrace WPC Decking. This process ensures uniform thickness, reinforced strength, and optimal weight distribution—critical for elevated terraces. Surface treatments like brushing or grooving enhance anti-slip WPC performance while preserving the look of natural wood.


Product Features


Lightweight Durability


The hollow core design makes Hollow WPC Flooring lighter than solid alternatives, easing transportation and installation without sacrificing strength. It supports heavy furniture and foot traffic while resisting warping or sagging.


Enhanced Insulation

The hollow core acts as a natural insulator, reducing noise from foot traffic and maintaining comfortable temperatures underfoot. Unlike concrete or solid wood, Eco-friendly WPC Decking stays cool in the sun and warm in cold weather.


Low-Maintenance Hygiene

This Terrace WPC Decking requires no painting, staining, or sealing. It's resistant to mold, mildew, and pests, and a simple clean with water and soap keeps it looking new.


Typical Uses
