Incarnation Secondary Glazing - Brunel House

Brunel House is a listed building being converted into luxury apartments. Replacing the primary windows was not permitted, so our client needed to look at a different solution to gain the thermal performance required.

The windows were large sashes, requiring heavy duty frames with tilt facility, providing simple access to the primary windows for cleaning and maintenance. An unusual and bespoke feature of this project was - at the architect’s request - trickle vents installed in the bottom of the secondary glazing track.

The end result is that, without any visible sign of works “Replacing the primary windows was not permitted” being done, tenants would experience comfort levels that match modern day double glazing, even though their windows are over 100 years old.
