Secondary Glazing For Listed Buildings

As Secondary double Glazing is an independent window system that is internally installed it does not have any implications on listed building regulations that prohibit the major alteration or replacement of the original windows.
Having tendered for countless listed projects and buildings in conservation areas we can assure you our secondary glazing windows always get approved for installation from local councils & governing bodies, We have previously helped clients get approvals from:

Thermal Improvements for Period Windows with Secondary Glazing

Take a look at our recently completed secondary glazing installation at The Gateways London. A Grade II Listed Building in Royal Hospital, London, Chelsea
We were contracted to carry out the installation of all windows to improve the buildings heat retention and Sound Proofing performance. We Installed 15 secondary glazing windows throughout the property while carefully preserving the characteristics of the original windows.
Our secondary glazing windows in London were designed to mimic the style and fenestration of the original windows in order to make the installation as discreet as possible while still providing access to the original windows openings.
All windows were manufactured from durable powder coated aluminum. Paying particular attention to the tone of white that had to be matched on the original windows.
The windows were glazed with Pilkingtons low emissivity K glass
Starting with the front room we installed a 4 pane combination to complement and replicate the original style already in place.
