🏆 Scottish EDGE Award Winners 2025 | 🔬 University of Salford Tested | 🏭 Made in Aberdeen | 🏛️ Approved for Listed Buildings
Secondary glazing made in Scotland. Independently tested.
InGlaze is an Aberdeen-based manufacturer of high-performance secondary glazing, designed specifically for Scotland’s homes and heritage buildings. Our acrylic panels fix to your existing window frames using our patent-pending flexible seal — creating an airtight barrier that dramatically cuts heat loss, reduces condensation, and quietens outside noise.
No planning permission required. No damage to your existing windows. No disruption to your home. Just measurably warmer rooms and lower heating bills.
Traditional windows aren’t perfectly straight. Our secondary glazing doesn’t need them to be.
Whether you live in a Georgian townhouse, a traditional granite terrace, a Victorian sash-windowed flat, or a listed building where double glazing is off the table — InGlaze is designed for you.
Designed in Aberdeen. Built from experience.
When we couldn’t find an affordable secondary glazing system that worked properly with traditional Scottish windows – uneven frames, non-standard sizes, and listed building restrictions – we decided to build one ourselves.
Years of development led to our patent-pending adaptive seal, independently tested at the University of Salford and proven to cut heat loss by 50%. InGlaze is manufactured at our own workshop in Aberdeen, designed specifically for the properties that need it most.
Why trust InGlaze?
We don’t ask you to take our word for it. InGlaze secondary glazing was independently tested at the University of Salford Energy House Labs — the UK’s leading facility for real-world building performance research. The results:
- 50% reduction in heat loss when fitted as a whole-window solution
- 41% reduction in heat loss when fitted to individual sashes while maintaining window operation
We’re also proud winners of the Scottish EDGE Round 25 Award — one of Scotland’s most competitive business innovation awards — and have received backing from the British Business Bank’s Start Up Loans programme.
InGlaze was founded in Aberdeen by Luci and Campbell, who built the business from the ground up after identifying a genuine gap: thousands of Scottish homes in listed buildings and traditional properties with no affordable, approved route to better insulation. Our solution fills that gap.
