Superior Versatility

Lasting Looks

At the Sea to Stay

What preservatives are in TimberTech decks' composite core to avoid rotting?

TimberTech composite decking is comprised mainly of high-density polyethylene and wood particles, but we also add proprietary ingredients to our formulation that offer increased protection from rot.


Will a TimberTech deck weather?

Any exterior product will fade over time to some degree – that’s the nature of nature. For the ultimate in steadfast color, our TimberTech AZEK boards are technologically engineered to show minimal fading, backed by a 50-year Fade & Stain Warranty. However, our uncapped wood composite boards will gradually weather, like wood, over time.
