Energy efficiency

Changing building regulations mean it has never been more important to offer new windows with great energy efficiency as standard.

The aluplast casement range easily achieves a BRFC A-rating and 1.4 U-value with standard glazing.*

If you are looking for higher performance, then triple glazing opens up options for U-values as low as 1.0.

*Standard glazing comprises 28mm double glazing unit, Planitherm Total plus coating, Edgetech warm-edge spacer bar and 90% Argon filled cavity. Other configurations may improve or reduce U-values and WER ratings
