Listed building secondary glazing
Secondary glazing for listed buildings is an outdated solution.
Reglazing original sashes with vacuum double glazing provides superior thermal insulation and noise reduction without the need for unsightly secondary glazing.
Why is Secondary Glazing an Outdated Solution for Listed Buildings?
Many homeowners ask us to remove their secondary glazing and reglaze the original sashes with vacuum glazing, and there is a good reason for this.
- Aesthetics – Some people feel secondary glazing looks unattractive from the outside or inside. Extra glazing bars and panes of glass can alter the look of your home.
- Reduced natural light – Secondary glazing creates another layer between you and the outside, which can marginally reduce the amount of natural light coming into a room.
- Extra cleaning – You now have an extra layer of glass that needs cleaning and maintenance.
- Cramped Window Operation and Reduced Space: Secondary glazing can make operating the original windows difficult and awkward. The extra framework also takes up valuable space.

The reglazing of typical sash windows with toughened vacuum insulated glass (VIG) double glazing, draught-proofing, and restoration of the frame and sashes costs approximately £1700 per window on average.
This is comparable to or even less expensive than high-end listed building secondary glazing.
However, VIG double glazing provides all the benefits of modern thermal performance and noise reduction while retaining the original appearance.
