About Selectaglaze

Come in and say hello

We have worked in thousands of buildings from the largest to the smallest, on several high profile and challenging projects – in particular listed properties. Over the years we have built up close connections with architects, designers, conservationists, acousticians, energy consultants, blast engineers, security specialists and test houses to create a vast knowledge base that we apply to all projects, large and small. So we can design, manufacture and fit the best secondary glazing solution, every time. Hear our team describe what makes Selectaglaze different. 

Original innovators 

We were among the first companies in the UK to offer secondary glazing and quickly became involved with new designs as the complexity of windows in the built environment became apparent. As an original designer we have been able to continuously develop products that meet the changing needs of buildings and clients. Bespoke design, prototyping and manufacturing is carried out in-house with performance testing usually completed by accredited test houses.

A lasting commitment to quality and service

We have always offered a complete service with full responsibility for design, manufacture and installation carried out by our own directly employed installation teams to make sure that products perform well, and clients are satisfied. This approach has led to numerous long term client relationships and many long serving employees. We are both ISO9001 and Investors in People accredited. In 2004, we were honoured to be awarded a Royal Warrant that recognises service and excellence.

Family ties since 1966

Our founder, Chris Childerstone had a long career with the RAF and a number of charter airlines, ending in the early 1960s after he suffered a burst eardrum. Entering the world of secondary glazing, Chris applied his skill and knowledge to creating innovative sound insulation solutions. Secondary glazing had just been introduced from Canada, and Chris organised early laboratory tests to prove its effectiveness. Selectaglaze took off, with projects around airports and busy roads for clients including BEA at Heathrow, Beecham’s offices on the Great West Road, Sainsbury’s headquarters and the Hyde Park Hotel. In 1974, Chris appointed his son, Meredith as Managing Director, and he continues to guide us as Chairman.

A new generation of Employee Ownership

A family firm since 1966, Selectaglaze is now proud to be an Employee Ownership Trust, creating a socially responsible, sustainable business with our employees at our heart. This transition continues our founding family’s legacy, rooting jobs in the community for the longer term.

Where to see Selectaglaze secondary glazing

“Selectaglaze helped us manage the whole process from beginning to end and we are delighted with the end result. Buildings with Grade II Listing need to be treated with care and respect and Selectaglaze proved to be the perfect company to work with in this respect.”
Harris Manchester College from University of Oxford
“Selectaglaze worked with Overbury and TP Bennet during the design phase to maximise both the thermal and acoustic properties of the existing building envelop. Selectaglaze was very helpful during this stage and surveyed all the existing window openings. The programme was phased with 2 floors being installed together and each phase 3 weeks apart. The site guys were very organised and snagged their own works as it was installed so there were zero defects at the end of the project. I would have no hesitation in recommending Selectaglaze for future projects.”
Bob Squires, Senior Project Manager from Overbury
