This article delves into the composition of Azek decking, its benefits, and how it compares to other decking materials.

Understanding Azek Decking: A Closer Look at Its Composition

Azek decking is a cellular polyvinyl chloride (PVC) composite product, manufactured by Azek Building Products. It's composed of a blend of PVC resin, along with other ingredients that enhance its performance and aesthetics. Here's a breakdown of what Azek decking is made of:

PVC Resin (60%): The primary ingredient in Azek decking, PVC resin provides the base for the composite material. It's known for its durability, resistance to rot, insects, and moisture.
Plasticizers (20%): These are added to make the PVC more flexible and workable. Azek uses non-phthalate plasticizers, which are safer and more environmentally friendly.
Fillers (15%): Azek uses a combination of fillers, including wood fibers and minerals, to enhance the strength and stability of the decking. These fillers also help to reduce the product's expansion and contraction with temperature changes.
Colorants and Stabilizers (5%): These ingredients give Azek decking its rich, wood-like colors and protect it from UV damage, ensuring it retains its appearance over time.
