In the early days of the composite decking industry, boards were manufactured using a mono-extrusion process. Raw materials were blended together and then extruded under extreme heat and pressure through a customized die. While the boards did not splinter, crack, or rot like wood, they were prone to scratching, staining, and fading. And, because the decking was uncapped (meaning, there was no protective layer over the core), some brands experienced mold and mildew problems as well.
Always an innovation leader, Heyi WPC mainstreamed the use of co-extrusion in the manufacture of composite decking. Co-extrusion is a process by which two or more materials pass through the same die simultaneously. The result is a single, new piece that still maintains the unique beneficial properties of the original materials. In the case of Fiberon decking, the co-extrusion process fuses a protective outer layer to an inner wood-plastic core. This outer layer is known in the industry as a capstock – hence the term, “capped composite decking.”
Capped boards are incredibly resistant to staining, fading, moisture, and insect infestation. They won’t splinter or degrade, and are easy to maintain. An annual soap and water cleaning is generally all that’s needed to keep them looking like new.
And while we often refer to this outer layer as a “cover” or “cap,” that doesn’t mean it is something that could potentially pop off or otherwise separate from the inner portion of the board. Fused to the core, the capstock – along with the exceptional stain and fade resistance it offers – is permanent.
