The Vision Range
Bespoke secondary glazing for the windows other systems can't fit — arches, circles, gothic tops and every non-standard opening.
Templated to your exact shape
Every Vision unit is templated on site, drawn in-house and manufactured in the UK. Semi-circles, full circles, gothic arches, quatrefoils and asymmetric shapes are all standard work.
- Semi-circular arches
- Full circle windows
- Gothic pointed arches
- Trapezoidal and bespoke shapes
Vision HD and Vision Ultra
Vision HD accepts sealed double-glazed units up to 28mm — deeper than any other secondary glazing system on the market. Vision Ultra takes 8.8–10.8mm laminated glass for maximum acoustic performance in slimmer sight-lines.
- Vision HD: up to 28mm DGU
- Vision Ultra: 8.8–10.8mm laminated
- Slimmer sight-lines than standard
- Approved for listed and heritage sites
