Initial cost is high. Plastic wood  decking purchase costs are higher than wood, but it saves later maintenance costs.So this can’t be said to be a real drawback. WPC decking is not 100% real wood. It is a composite of wood fibers and plastics,Therefore, the thermal expansion and cold shrinkage of plastic should be taken into account when installing,Many projects cause the thermal expansion of the floor to arch because there is no gap between the boards.

Composites may last longer, but the initial investment is likely to be higher. Many composites are formulated to be fade, scratch, and stain resistant, but no lumber is immune to the elements. Although composite lumber may resist these marring effects better than other materials, it will still show signs of wear over time. Composite lumber often has a plastic-like or synthetic appearance. Although manufacturers do mold the product with a wood grain or brush stroke pattern, some consumers simply do not like the artificial sheen.
