Triple-glazing sash windows
Triple glazing sash windows were long considered the most energy efficient window option. However, advances in glazing technology have challenged this notion.
Vacuum double glazing provides superior insulation compared to standard triple glazing.
Additionally, vacuum double glazing tends to be thinner and lighter than triple glazing.
This makes it an ideal retrofit solution, as it can be installed directly into existing window frames without the need for costly frame replacements.

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.
