TimberTech has expanded its Earthwood Evolutions line of composite decking with two new colors in a lower-priced Terrain Collection. The offerings — brown oak and silver maple — are in addition to TimberTech’s Tropical and Natural decking lines.

The core of the decking is made from reclaimed wood fiber and a combination of recycled and virgin high-density polyethylene plastic, according to TimberTech. A plastic cap completely encapsulates each board.

What makes the Terrain decking different is a scalloped underside that reduces the amount of material in each board and allows the company to sell the decking for about 20% less than other Evolutions decking. Exact retail pricing wasn’t announced.

Planks come with a 25-year fade and stain warranty. They’re available with a grooved profile for hidden fasteners or a solid profile that can be face-screwed, in lengths of 12, 16, and 20 feet, along with matching fascia. Boards are about 53/8 inches wide and 1 inch thick and span 16-inch on-center framing.
