We provide double glazing in Swindon, and surrounding areas. Replacing double glazing is one of the best ways to improve the energy efficiency of your home. Double glazed units are made up of 2 panes of glass, with an insulating gap in between, keeping the warm air in and cold air out! All of are products come with a 10 year insurance backed guarantee.


We also offer secondary glazing for customers who live in listed or conservation areas, you don’t need permission to install secondary glazing as it doesn’t change the appearance of your property! It’s fantastic for keeping the noise out and the heat in.


This means less draughts and reduced heating bills. Installing double glazing will also reduce the noise and condensation in your home. All of our products are A rated and come with toughened glass as standard.. View our Brochure
