Energy Rated window and doorsets by Assure
The performance of double and triple glazed, energy-efficient windows and doors depends on a number of factors, including how well they stop heat passing through the window, how little air can leak in or out around the window and how much sunlight travels through the glass.
Windows and doors are rated and labelled using a familiar ‘traffic-light’ system to guide homeowners towards energy-efficient products. Window Energy Ratings (WERs) and Doorset Energy Ratings (DSERs) are illustrated on a scale of A++ to E.
Assure can help you with this
Fabricators and installers are now able to join the Assure Rating Register scheme. This allows them to calculate their own U-Values and energy ratings for a variety of products. Our approved calculator has been accredited by both BSI for use towards CE Marking and by the BFRC. It has also been endorsed by the Energy Saving Trust.

The Energy Saving Trust operates an endorsed product standard and information about this can be found at EST Online
Please note: The Assure Rating Register is a stand alone scheme and members of this scheme do not have to be members of the Assure Competent Persons Scheme.
