Materials

Discover Your Ideal Decking Material

Pressure-treated wood

The most common material; soaked with chemicals against insects, moisture and rotting.

Cedar

Considered a higher quality material than pressure-treated; also has natural tannins making it resistant to insects, rotting and decomposition

PVC

Polyvinyl chloride plastics; much more expensive than wood that requires almost no maintenance, including staining and sanding

Composite

A mix of various density polyethylene and wood; low-cost alternative that requires minimal care, not even sanding or refinishing.

IPE

Exotic high density hardwood from Central and South America; due to high density and natural tannins resistant to rotting and insects

Fiberglass

Waterproofing deck coating material; one of the longest lasting alternatives with low maintenance resistant to moisture
