100% Smarter Than Wood™. At TimberTech®, we know life’s tender moments happen on our tough decks. So we make them durable enough to withstand almost anything your family, friends, and the elements dish out. It’s important to us that your deck looks gorgeous year after year, so we don’t cut corners. We even cap the bottom of the deck board—a step some manufacturers skip—because TimberTech’s got your backside.
