Thermal Performance
With any extension, the worry is that it won’t retain heat as well as your original structure has done. With our extensions, you do not have to worry about thermal efficiency. We use the highest quality products.
Our windows have a Windows Energy Rating of A+12. That way you know that our glass extensions will stay warm, which in turn will lower your energy bills and save you money in the long run.
Investing in one of our extensions would be worthwhile as they are cost effective and will save you money in the long run.
Gone are the days when it was too hot to use your glass extension in the summer and far too cold to use it in the winter.
