Don't take our word for it.

Retro Panes have been installed in homes across the country. They’re the preferred choice for secondary glazing, especially where traditional double glazing would be too disruptive. Here’s what our customers say:

Customer Spotlight: Michael

We spoke to Michael after he installed Retro Panes in his home. With traditional single-glazed timber windows, Michael wanted a solution that didn't cost a fortune, and one that didn't require a big job.

  • "Retro Glazing's solution seemed like the best option, both on cost grounds (a lot less than traditional double glazing) and on planning grounds (we live in a conservation zone). So we had the downstairs windows (two bay windows) done first, and liked the result so much that we had them back to do half the upstairs as well!"

    Rob

  • "Fantastic service, quick, efficient and friendly staff. Windows look amazing and already detect less noise and no condensation."

    Jim

  • "This morning, for the first time, I did not have to mop up condensation, and I seemed to feel the house was a little less cold."

Protecting our planet, one pane at a time.

Windows are the biggest cause of heat loss in residential buildings, with period properties having the highest percentage of single glazing in the country.

By upgrading single-glazed homes with Retro Glazing, we want to enable everyone to improve their energy consumption easily and affordably, while lowering CO2 emissions.
