The secondary glazing specialists
Selectaglaze Secondary Glazing


Selectaglaze have been leading UK secondary glazing manufacturers, designers and innovators since 1966.

Secondary glazing involves the installation of new, fully independent secondary window frames on the room side of the existing or primary window.

The key benefits offered by secondary windows include improved acoustic insulation protection against noise pollution from road traffic, aircraft and the 24 hour society. Secondary glazing systems also improve thermal insulation, saving energy and reducing fuel bills; increased window security by providing a protective barrier against intruders and blasts.

  Selectaglaze secondary glazing systems are widely used within offices, homes, hotels, museums, education and healthcare premises laboratories and clean rooms as well as public buildings. They are also uniquely suitable for listed and heritage buildings.


Selectaglaze has a permanent display of its secondary glazing systems at the Building Centre - 26 Store Street (just off Tottenham Court Road) London, WC1E 7BT. Open 9.30am-5.15pm Mon-Fri. 10.00am-1.00pm Sat.
