Toughened Glass
Heat-treated safety glass, four to five times stronger, that crumbles instead of shattering.
Glass heated and rapidly cooled so the surface is in compression. It is roughly four to five times stronger than annealed glass of the same thickness, and if broken it granulates into blunt pieces rather than shards.
Mandatory in our specification for doors, low-level glazing and anything full height.
Key highlights
- 4–5× stronger than float
- Granulates safely when broken
- Required for doors and low glazing
- Withstands thermal stress
- Cannot be cut after toughening

Frequently asked questions
uPVC insulates far better and costs less for ordinary residential openings. Thermally broken aluminium is stronger, so it carries larger panels with slimmer frames. We usually specify uPVC for bedrooms, kitchens and bathrooms, and aluminium for very large sliders, stairwell glazing and anything above about 2.4 metres tall.
Not if the profile is UV stabilised and lead-free, which ours are. Yellowing happens with cheap unstabilised profile or recycled material. We supply a written warranty against discolouration.
An acoustic laminated inner pane inside a double-glazed unit, with the two panes at different thicknesses and a wide cavity. Just as important, choose a casement or tilt-and-turn window rather than a slider, because the sash needs to compress onto its gaskets to seal.
Yes. We bend profile on a heated forming table from a site template, so semi-circular, segmental and elliptical heads are all possible, fixed or with an operable lower sash.
