Installing Secondary Double Glazing: A Cozy Upgrade Without the Hassle

Let’s face it—old windows can be charming, but they aren’t always the best at keeping out the cold or street noise. Replacing them? Expensive. Time-consuming. Often not allowed if you’re renting or in a listed building.

Enter secondary double glazing—your secret weapon for a warmer, quieter home, without touching your existing windows. It’s like giving your current windows a smart, invisible upgrade.

Secondary double glazing is a second pane of glass added inside your existing window frame. It’s discreet, energy-efficient, and often removable. Think of it as adding a layer of insulation—without any of the major work.

What If You Have Blinds?

No problem! You can keep your existing blinds. If they’re mounted inside the window opening (where the new glazing goes), a small build-out can be installed:

• This build-out is like a mini frame extension that shifts the glazing forward.
• It gives you the space to reinstall your current blinds exactly where they were, just slightly further out.
• The result? Everything still looks sleek and tidy—and you don’t have to buy new blinds.

Secondary glazing is one of those projects that feels small—but makes a big difference. You get to keep the charm of your original windows and enjoy the benefits of modern comfort.
