1. Thermal efficiency
It’s well known that uPVC is a low conductor of heat, helping to retain warmth within a building and keep the cold out. This is further enhanced by designing multiple chambers inside the window profiles, allowing them to trap air and create a thermal barrier.
Add double or triple glazing to a uPVC frame, and U-values as low as 0.8 W/m²K can be achieved.
According to the British Fenestration Rating Council (BFRC), when it comes to ‘A’ rated windows, uPVC outperforms any other material, with 10 times more uPVC windows achieving an ‘A’ rating compared to the nearest alternative.
