Which lasts better, uPVC or WPC? Here's an honest look at durability.
WPC (wood-plastic composite) is a blend of wood fibre and plastic, used mainly for doors and some fittings. uPVC (unplasticised PVC) is the material used for window and door frames. Both are moisture-resistant alternatives to timber, but they suit different jobs.
Both are far more durable than timber in moisture — neither rots — but they behave differently under sun and load.
For window frames, uPVC's durability is well proven — reinforced, UV-stable, decades of life. For doors, quality WPC is durable too. As always, the quality of the specific product matters more than the material category.
Both outlast timber and resist moisture. For window frames, uPVC's reinforced, UV-stable durability is well proven; quality WPC doors are durable too. The specific product's quality matters most.
For windows, uPVC is the proven long-life frame. For doors, both are durable. It depends on the application and product quality.
Yes — neither rots like timber, which is a core advantage of both.
