Timber Tech

The most realistic wood looks on the market, our decking endures year after year without fading, staining, splintering, peeling, cracking, or rotting.
TimberTech delivers enduringly beautiful designs and superior performance, whether choosing a composite, PVC, or metal collection.
PVC decking is decking made from polyvinyl chloride (a type of plastic), with no organic material, such as wood flour. Because there’s no organic material, PVC is engineered to avoid one of the biggest pitfalls of organic decking — moisture invasion, which can lead to mold, mildew, and rot.
Composite materials are created with a blend of polymers and organic wood fibers for improved durability and weather resistance. They often feature three- or four-sided polymer caps that prevent water penetration to protect the decking board’s core.
Receive the full aesthetic experience of wood without the strenuous, costly, and constant upkeep required of lumber.
Over 20 finish options across nine collections, to find the look that’s right for your home.
Engineered from 60 to 85% recycled content, Timber Tech products perform better than wood every time, and help homeowners create nature-inspired, sustainable outdoor living spaces.
Your investment is protected by industry-leading warranties, including Limited Product and Fade & Stain Warranties that range from 25 years to Lifetime, depending on the collection.
Timber Tech Vintage and Landmark Collections have an Ignition Resistant designation and a best-in-class flame spread rating.
