Don’t think of secondary glazing as second best! This clever product is designed to give you the advantages of double glazing even when you can’t replace your windows.

Fitted on the inside, so the external appearance of your property doesn’t change, our secondary glazing offers twenty-first century performance on even the oldest of homes. You’ll get the benefit of reducing noise, eliminating draughts, regulating ventilation and extra security.
Our secondary glazing solutions are an attractive option, especially if you live in a listed building, traditional or heritage home where you want or have to preserve the original characteristics of your windows.

HGI`s secondary glazing is available in more than 200 colour options.
