Are uPVC windows energy efficient?

uPVC windows from T&K Home Improvements excel in their energy efficiency for a number of reasons, allowing you to save money on your energy bill. For starters, they use high-quality frames which contain multiple heat-trapping chambers. Many of our uPVC window styles also come with the option of triple glazing, but double glazing is available on all of them.

Are uPVC windows bad for the environment?

As uPVC is a type of plastic, it's easy to assume that it's not very good for the environment. However, this is not the case with our uPVC windows; ours are not built from any single-use plastics and the frames are also fully recyclable. Our uPVC window manufacturer, Emplas, also recycles any waste generated from 'end of life' products and manufacturing.
