Your Guide to Retrofitting Double Glazed Windows

Installing double glazing can bring down heating and cooling energy bills up to 60%, reduce UV rays by 75% and block 70% of noise.

Retrofitting double glazing to existing windows can boost your home’s insulation, cutting energy bills and keeping your place comfortable

What does “retrofitting” double glazed windows mean?

Retrofitting means adding a component or accessory that wasn’t in the original build. For home renovations, that means swapping out single-pane glass for new double-glazed windows without altering the window cavity.

We can even install double glazing in your existing window frames.

How we retrofit double-glazed windows

Single-pane glass is a poor insulator. So in winter, cold air gets in through the glass, or anywhere the frames have warped. And in summer, your windows invite the sun to heat up your home and fade the furniture.
