Modern living in one of the world’s most exciting cities has its drawbacks. London, with all it glory, is a very busy, noisy city and trying to live a comfortable, quiet life often seems impossible. Secondary glazing is by far the most effective way of excluding environmental noise, making your office or home noticeably more serene.

A further application of secondary glazing is thermal insulation and complete draught exclusion. Old, single glazed windows are notorious at letting all the heat escape, resulting unpleasant cold spots and very expensive heating bills during the long British winters.
