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.

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.
