Selectaglaze Limited

Founded in 1966 and Royal Warrant Holder since 2004, Selectaglaze has been designing and manufacturing secondary glazing from its factory in St Albans, for installation in projects across London and the UK.

As a fully independent window, fitted room side of the primary glazing, the secondary window raises energy performance – stopping draughts and heat loss, improves acoustic insulation and can add varying levels of security. It is generally accepted by heritage agencies for retrofitting in Listed buildings, as it is often the only way to upgrade window performance and is a reversible adaptation. It can also be used in new-builds as a sound noise insulator, where high acoustic requirements need to be met.

Selectaglaze offers a free technical advisory service, site visits, samples and RIBA approved CPD seminars. CAD files, BIM objects and product data sheets are all available to download from the website.
