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.

  • It's definitely the most cost-effective option, and you don't even notice that they're there.

  • It was really easy... as simple as slotting them into the window frame.

  • The rooms are immediately warmer. We're using the central heating quite a bit less.

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.
