Composite Decking

Windi decking is the new generation made by co-extrusion, which is the latest technology in the industry. Co-extrusion decking is composed of core and cover. The core is just the traditional WPC decking, which is sufficiently ensure the strength of materials. The cover protects from color-fading away, water-absorption and with longer usage time. Performing better than any traditional composite common WPC.

What is co-extrusion composite decking?

What is co-extrusion composite decking? Co-extrusion is also called “capped” Or “cover” Deck. It is important distinction to note because that earlier generations of composite decking were uncapped, the big difference is that co-extrusion composite decking has a “cover” That provides added protection against the elements and everyday living. As a result, they were far more vulnerable to staining and fading. Windi co-extrusion decking, the core is the traditional wood plastic composite materials (along with our g series and h series traditional decking), while the extruded surface is made of multi engineer plastic with an outer shell of plastic that completely encapsulates the board in an impermeable layer of protection from scratches, stain and fading. The extrusion process creates the decking with highly durable, long lasting and resistant to staining, fading and relative impact.

  •  Better resist to UV, better color stability; 
  •  Better resist to moisture and termites; 
  •  Better at resisting to mold and mildew; 
  •  Less water-absorption, less rotten; 
  •  Extreme durability and reliable; 
  •  More natural surface: wooden texture, looks like real wood; 
  •  Low maintenance at an excellent price.
