Invision Secondary Glazing installs bespoke aluminium secondary glazing nationwide, working in partnership with Granada Glazing of Sheffield, whose systems are manufactured in the UK. An additional glazed panel is fitted inside the existing window, leaving the original frames and external appearance untouched while cutting heat loss, reducing noise and adding a further barrier against intrusion. The team has more than sixty years’ combined experience and each installation carries a ten-year warranty. Completed projects include an old cottage in Ashbourne, Derbyshire, where thicker glass was specified to deal with draughts, and a school where security was the primary concern.
Suitable for: listed houses and buildings in conservation areas, especially on busy roads, where the primary windows cannot be replaced.
Services: survey, supply and installation of aluminium secondary glazing; acoustic glazing; thermal upgrades; security glazing; domestic and commercial installations.
Location: not stated on the site; installations nationwide.
