Product information

Product name


Product description

AZEK Deck Harvest mono-extruded deck boards are made from foamed polyvinyl chloride (PVC) and cellulosic fibre with ultraviolet (UV)-resistant additives and colorants. AZEK Deck Arbor, Terra and Harvest co-extruded deck boards are made from PVC and proprietary mineral additives with UV-resistant additives and colorants. The composite products are manufactured through a continuous extrusion/coextrusion process into planks of solid cross-sections of varying thicknesses. Typical board dimensions are 140 mm wide by 25 mm thick.

The product is intended to be used as exterior decking to be installed over traditional structural wood framing.
