Retrofit Double Glazing

Enjoy the benefits of double glazing using your existing joinery. 

Retrofitting is a cost effective way to replace existing single pane glass with double glazing. This improves the thermal properties of your home, without compromising the look of your joinery.

Retrofit double glazing reduces condensation which helps create a drier, healthier home for you and your family. It will keep your home cooler in summer, warmer in winter, and more comfortable all year-round, with increased sound proofing.
