  • TimberTech Terrain Collection Rustic Elm


    TimberTech’s Terrain Collection is popular in Ontario for its earthy, natural tones and hard-to-beat durability. TimberTech Terrain Collection Rustic Elm is a composite decking board specially engineered to withstand harsh weather. The solid brown color and authentic-looking texture looks like real wood—all year round and whatever the weather.

    The decking boards look just like real Elm. But they’re made from high-end composite capped on all sides with a polymer shell. The protective layer ensures that the TimberTech Terrain Collection Rustic Elm deck will resist stains, scratches, and fading. The boards also stand up strong against mold, mildew, and moisture.

    All TimberTech products are backed by a 25-year scratch and stain warranty. That’s the guarantee provided by an industry-leading decking manufacturer.

    Product Dimensions

    • Actual Dimensions –  0.94″ x 5.36″ (23.88 mm x 136.14 mm)
    • Length – 12′, 16′, and 20′ (366 sm, 488 sm, and 610 sm)
    • Shape of boards – available in both grooved and square-edged varieties (16′ and 20′ only)


    TimberTech Terrain Collection Rustic Elm boards look great and last for decades. Decking contractors in Ontario also love the easy installation. CONCEALoc® hidden fasteners tend to work best with TimberTech products. However, FUSIONLoc® hidden fastener systems also provide a smooth, fastener-free surface. They’re easy to install, too.

    However, hidden fasteners don’t work when using square-edged boards. They also don’t fit picture framing, stairs, or skirting. When installing square-edged boards, we recommend using the TOPLoc™ or Cap-Tor Face Fastening Systems.

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

    Remember that the deck’s underneath joist must be 16” on-center. If you plan to install the decking boards diagonally, the underneath joists’ structure must be 12” on-center. In that case, you’ll end up spending around 35 percent more on fasteners than you would with joists 16” on-center.

    Color combination

    TimberTech Terrain Collection Rustic Elm is designed to enhance the outdoor aesthetic of your home’s exterior. Picture framing isn’t a necessity, but it does have some advantages. The panels for the picture frame should be darker than those for the main deck—this creates an eye-catching visual contrast. TimberTech Tropical Collection Amazon Mist can add some flavor as a picture frame for the Rustic Elm main deck.  


    TimberTech Terrain Collection Rustic Elm boards come ready with raisers and fascia boards (0.56” x 7¼” x 12’ & 0.56” x 11.75” x 12’, respectively). These additional boards also come in Rustic Elm.
