🏆 Scottish EDGE Award Winners 2025 | 🔬 University of Salford Tested | 🏭 Made in Aberdeen | 🏛️ Approved for Listed Buildings
Secondary glazing solutions made in Scotland, proven by science
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.
Whether you live in 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.
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.
