Secondary Glazing
Designed for maximum discretion, secondary glazing is installed inside your existing windows without altering the external appearance of your property. Our made-to-measure units are crafted with precision, ensuring that the bars and sightlines align perfectly with your original windows and blend seamlessly with your home’s exterior. A period building with original windows is a prime candidate for secondary glazing, as it enables homeowners to enhance insulation and noise reduction without compromising the property’s character or requiring planning permission in most cases. Unlike full window replacements, secondary glazing is a practical solution for listed buildings and conservation areas in London, where planning restrictions are often in place.

Preserving Period Charm with Modern Performance
We offer 6.8mm, 8.8mm, and 10.8mm laminated acoustic glass, which, when combined with a deep cavity between the existing and secondary window, provides significantly better noise reduction than a standard replacement window with acoustic glass.
Made from lightweight aluminium, secondary glazing involves installing an additional pane of glass on the inside of the existing window frame, creating a secondary barrier against sound. It provides an effective alternative to replacing original windows with modern double glazing, enhancing thermal efficiency, reducing noise, and improving security while preserving your home’s charm and heritage.
For ease of use, we offer a range of secondary glazing styles, including lift-out, hinged, and sliding options. These options allow for proper ventilation and easy cleaning. Every unit is custom-made to fit even uneven window frames, ensuring a seamless installation in older properties.
Our secondary glazing units use premium-grade, high-strength aluminium for outstanding durability and performance. Every unit is precision-engineered at our advanced facility, reflecting the best of British craftsmanship.
