25 Years Ago Azek invented pvc trim
It started with a breakthrough idea—make a trim board out of PVC, the same size as traditional dimensional lumber. The idea caught on and grew. AZEK Trim solved a centuries-old problem: rot. Exterior building materials — especially organic materials — break down with moisture. AZEK Trim does not. This year, we’re celebrating 25 years of innovation—in trim, siding, moulding, and cladding that outperform wood, fiber cement, and engineered wood in every way.
