  • TimberTech Terrain Collection Stone Ash


    TimberTech Terrain Collection Stone Ash decking boards have a soft, natural appearance that is truly rare on the composite decking market in Ontario. They’re built from a high-tech material that ensures durability. They also have the solid gray color of real Ashwood, which can enhance the beauty of your home’s existing exterior. Each board is also protected by a polymer cap.

    The polymer cap is engineered to maximize authenticity and durability—it has the wood grain of real Ash, but is specially designed to resist harsh weather. TimberTech Terrain Collection Stone Ash are protected from mold, mildew, and moisture. Plus, they won’t stain, scratch, or fade. The high-tech polymer cap makes annual re-sealing and staining a thing of the past.

    That durability is guaranteed: All TimberTech decks come with a 25-year scratch and stain warranty.

    Product Dimensions

    • Length – 12′, 16′, and 20′ (366 sm, 488 sm, and 610 sm)

    TimberTech Terrain Collection Stone Ash decking boards are popular with contractors and customers in Toronto because they’re super easy to install. Overall, the installation process goes best with CONCEALoc® hidden fastener systems. These hidden fasteners ensure that the deck’s surface is smooth and fastener-free—like real wood! FUSIONLoc® hidden fasteners are another good option that makes the installation easy.

    In some cases, square-edged boards are the preferred option for the main deck. For square-edged boards—and when installing picture framing, stairs, or skirting—exposed fasteners are needed. TOPLoc™ and Cap-Tor Face Fastening Systems are the best option for square-edged boards from TimberTech.

    Cortex and Pro Plug systems are not options for TimberTech Terrain Collection because of groove channels underneath of decking boards.

    Take note: the deck’s underneath joist must be 16” on-center. When installing the decking boards diagonally, the underneath joists’ structure must be 12” on-center. For diagonal installation, you’ll end up spending around 35 percent more on fasteners than you would with joists 16” on-center.

    Color combination

    The consensus is clear: designers and contractors in Ontario think TimberTech Terrain Collection Stone Ash looks gorgeous on its own. Picture framing is not required. However, some feel that the right picture frame can truly add to the main deck’s appearance. If adding a picture frame to Stone Ash, be sure to pick a darker color that creates the right contrast. We recommend TimberTech Terrain Collection Brown Oak. It has a solid brown color that works well visually with Stone Ash.


    Every TimberTech main deck comes with included raisers and fascia boards (0.56” x 7¼” x 12’ & 0.56” x 11.75” x 12’, respectively). These extra boards are available in TimberTech Terrain Collection Stone Ash.
