Window Energy Ratings

Vertical Sliding Sash Windows

Window Energy Ratings are different for each style of window – Elegance or Universal – and whether or not they have a standard or deep bottom rail. Click to enlarge the images to the right for the details.

Windows account for around 20% of the heat loss from a home. Current Building Regulations require new builds to have a minimum Window Energy Rating of ‘C’.

As replacing windows represents a significant investment it’s important to choose windows with a high WER at the outset. All our uPVC Vertical Sash Window products meet or exceed existing Building Regulations requirements. Our Elegance VS with Deep Bottom Rail achieves an “A” Energy Rating (see right.)

WERs are achieved by selecting the appropriate glazing. Please Contact Us to discuss your requirements.
