Energy Performance

With rising energy costs, fuel costs and living costs, the last thing your customers want is to do is throw valuable money out of the window. But that is exactly what they could be doing if the windows aren’t energy efficient. Did you know that around 20% of heat escaping from a home is lost through its windows?

Energy efficient windows from Seven Day are manufactured using the finest quality materials and the latest technology in glass and spacer units, including the world’s leading weatherseal gasket - all meticulously deigned to deliver advanced energy rated performance. Our energy saving windows allow heat generated from your home to be reflected back into the room but also trap free heat from the sun through solar gain, thus maximising the thermal performance of our windows.

All of our windows are available in either double or triple glazed options and can be manufactured in a choice of A++ to C WER Energy Ratings.
