Middleton Glass supplies high quality replacement double glazed and triple glazed units. This ensures we have the best quality possible for you and your home as we strive to supply products of the highest standard.

Window Energy Ratings and A-rated windows - Current activity in UK. The Window Energy Ratings system is already being used as a benchmark to fairly assess the thermal efficiency of windows. The system allows different configurations of windows to be compared on a like-for-like basis on the thermal efficiency. These windows use argon and krypton gas in the cavities for increased (WER) energy ratings coupled with warm-edge technology.

The Double Glazed Units used by Middleton Glass are suitable for use in wooden and plastic frames and in most cases they can be fitted in to metal frames. All products used in the manufacture of these windows comply with BSI standard, ensuring the end product is of the highest quality.

Middleton Glass are able to supply windows to fit any gap from 14mm all the way up to 50mm. In case you need something a bit thinner we offer, Superslim units, in thickness from 4-4-4 but still achieve a great U value in some cases a better U value than standard units.
