Double glazing’s broad definition is; two panes of glass separated by a sealed pocket, typically air or gas. However within double glazing there are three installation options; retrofit double glazing, double glazed insert windows, and full replacement windows & doors. 

The addition of double glazed glass can create many benefits for your home such as increased warmth, reduced condensation and reduced sound transmission, however, there are different options that have an affect on the overall effectiveness, look and feel of your install.

The cost of double glazing is contingent on factors such as the chosen service type, number of windows & doors to be replaced, and their respective sizes. For this reason we provide FREE, no obligation measure and quotes to guarantee that we supply you with accurate pricing. 

A complete window schedule is also provided with each unit priced individually. This is helpful for those on a budget so they know exactly what each room in the house will cost to double glaze. The choice to undertake double glazing in stages is very much an option.
