About Glazed Window Systems Ltd
One team, one guarantee, one mission - every UK home sealed in aluminium
Glazed Window Systems Ltd is a West Midlands aluminium door and window specialist. We were founded on a simple idea: the UK home deserves better glass. For too many years the default was chunky uPVC, swollen timber frames, and composite front doors that sag after a decade. We wanted to change the default - to make slim, secure, thermally excellent aluminium doors and windows the first choice for every self-builder, every extension, every full renovation, and every forward-looking developer.
We operate from a dedicated fabrication and distribution base in Birmingham, delivering right across the UK. We supply builders and installers on supply-only terms with trade pricing. We also run an in-house install team for homeowners who want a stress-free start-to-finish job. And we partner with a hand-picked network of builders for full kitchen extensions, side-return builds, two-storey extensions, and conservatory roof replacements - projects where glazing is the hero feature.
Everything we sell is Part L compliant. Every door is PAS 24 secure. Every frame is powder coated for a 25-year life. Every installation carries a 10-year guarantee. Those are the basics and we never compromise on them. Beyond the basics we compete on detail - concealed 3D-adjustable hinges, triple gaskets, flush thresholds, astragal bar bonding, soft-close dampers, ekey fingerprint options on front doors. The fiddly details are where a good door beats a cheap door.
