uPVC (Unplasticised Polyvinyl Chloride) is a type of plastic that’s been engineered to be rigid, durable, and weather-resistant. Unlike regular PVC (which is softer due to added plasticisers), uPVC is tough and built to withstand the elements.
It’s been a go-to material for window frames and doors for decades because:
It doesn’t rot, warp, or corrode like timber.
It requires almost zero maintenance.
It provides excellent insulation, making it energy-efficient.
Essentially, if you want windows that look good without the constant upkeep, uPVC is your best mate.
