Secondary glazing — also called secondary windows — is a slim, independent pane fitted on the inside of your existing window. The original window stays exactly as it is, while the new internal pane adds insulation and dramatically cuts noise. It's the approved upgrade for listed buildings and the affordable way to warm and quieten any home.
Every type made to measure, expertly fitted and fully guaranteed. Explore the options below or ask us to recommend the right choice for your home.

Learn moreOur secondary glazing are made to measure for listed homes, flats near busy roads and rooms losing heat through old windows, built in discreet slim-line internal glazing and fitted by experienced, directly-employed installers. The result is warmth, quiet and draught-proofing without altering the building — and a finish that lasts. Every job starts with a free, no-obligation survey so the measurements, spec and price are right before anything is ordered.
We offer lift-out, hinged, sliding and fixed panels, with a wide range of colours, glazing and hardware so your secondary glazing suit the age and style of your property. At survey we talk through the options and recommend the best specification for your budget, your exposure and the look you want.

No — that's the point. Your existing windows stay in place. Secondary glazing fits neatly inside the room behind them, which is why it's accepted in listed and conservation properties where you can't change the original frames.
The price of secondary glazing depends on size, material, glazing spec and how many you need, so we give a fixed, itemised quote after a free survey — no pressure and no hidden extras. Ask about interest-free finance to spread the cost.
