TimberTech & Azek were recently rebranded under TimberTech, an Azek Company. TimberTech has long been an industry leading composite decking brand and leading producer of composite railing. Azek has been a proven PVC decking company with some of the best decking boards available in the market. Today, TimberTech incorporates a wide range of materials and profiles for decks and railings alike.

CPG International was founded in 1983 and branded its PVC decking - Azek in 2001.TimberTech was founded in 1997. The two companies were competitors until the parent company of Azek purchased TimberTech in 2012. The two were kept separate until 2015, when TimberTech and Azek were rebranded, under CPG Building Products. In 2019 Azek and TimberTech were rebranded TimberTech. Today, Azek incorporates all PVC decking, and is a "collection" so to speak, under TimberTech.

Deck fastening has always worked to keep up with advancements and changes in the industry. Traditionally TimberTech decking has been installed with TopLoc Face Screws, color matched to the composite or pvc decking, and is still a preferred method for some applications. Azek PVC was one of the first to utilize Cortex screws and plugs. Cortex truly revolutionized the way we understand hidden fastening with the ability to fill the top of a screw hole with matching decking plugs. Perhaps the next greatest advancement was the creation of CONCEALoc Hidden Fastening Clips. Now days, TimberTech Composite Decking as well as Azek PVC Decking has grooved boards that utilize CONCEALoc fastening clips. Square edge TimberTech Decking Boards are available in 16 foot and 20 foot lenghts. are used for stairs and perimeter decking boards, and are fastened with face screws or a screw and plug system.
