Adapting heritage buildings in London and the UK with secondary glazing

With its large stock of traditional buildings together with an increasing need of acoustic and security solutions, secondary glazing is playing an increasingly important role in adapting existing London buildings for the demands of the twenty first century.

In-house product development

We believe in continual product development which has resulted in an extensive range of systems to suit almost any type of building. Applications range from; noise reduction, thermal insulation and environmental controls; to protection systems for bomb blast, ballistic, physical attack and fire. With ever increasing demands on the performance of buildings, we strive to ensure our products meet their specific needs. Many projects we have been associated with have gained BREEAM ratings. Selectaglaze has worked extensively throughout London and the Home-Counties. Our extensive product range has evolved with the changing needs of the city and we remain responsive and innovative to the current day.

Accreditations and Affiliations

Wherever possible the products are independently tested and certified so that clients feel secure in their quality and performance. Selectaglaze is certified to ISO 9001. We undergo regular audits through the Loss Prevention Certification Board to demonstrate continued compliance. We have a range of other accreditations covering training, security and health and safety.
The company has also been accepted as a member of a number of industry trade associations. These can be seen on the accreditations and affiliations page.
