With as much as 18% of heat lost through windows, double-glazing can greatly improve the heat retention of your home while keeping out unwanted elements.

Lasting for up to 20 years, if you replace single-glazing with double-glazing you could save around £180 a year on heating bills. An additional saving of £30 a year can be made by draught-proofing the gaps around your windows.

Where double-glazing isn’t suitable, secondary-glazing can be installed. This entails a secondary pane of glass being fitted inside the existing window reveal.

Suitable for listed buildings, period properties and homeowners looking for an alternative to double-glazing, secondary-glazing offers non-intrusive and cost effective insulation.
