Are wood composite decking environmentally friendly?

Yes. Because WPC will not splinter, warp or fade the way wood does, it dramatically reduces the wasteful cycle of repair and replacement and eliminates the frequent application of environmentally harmful paint, sealers and stains.

Will WPC decking and railing fade in color?

Most materials exposed to UV and other weathering effects will fade.WPC decking and railing solutions are blended with high quality raw material and UV-inhibiting pigments to minimize fade and produce products consistent in color. All products will fade evenly. WPC Evolutions has an added 25-year Fade.

What's the lifetime value of WPC?

Because WPC never rots or warps, painting and staining is not required, however with pressure-treated wood decks, these costs add up over time. After four years, the total cost of owning a WPC deck equals the cost of a pressure-treated wood deck. Over the life of the purchase, WPC offers a far greater value than wood. Clean it twice a year and you're done so you can spend more time enjoying your outdoor living space, rather than working on it.
