Thermal performance is more important than ever and our uPVC windows stand out as an excellent choice if you are energy conscious.
Our casement windows achieve exceptional thermal efficiency, achieving Window Energy Ratings (WER) of up to A++. They utilize multi-chambered uPVC profiles to trap pockets of warm air, drastically slowing heat transfer. Our casement windows also feature a continuous bubble gasket that effectively eliminates draughts and prevents heat loss.
Our casement windows offer the flexible option of double or triple glazing, boasting incredibly low U-values. The advanced double glazing easily surpasses standard building regulations, while our high-performance triple glazed options achieve U-values as low as 0.66 W/m²K, making them fully Passivhaus compliant. This creates a powerful thermal barrier that keeps your home comfortable all year round, significantly lowering your energy consumption and reducing your heating bills.
