Whole Pane Secondary Glazing

Suitable for all modern, traditional or heritage windows in homes and workplaces. Custom made for your windows.

InGlaze Whole Pane secondary glazing is our full-frame solution for larger windows, bay windows, and any room where maximum thermal performance is the priority.

Each panel is custom-cut at our Aberdeen factory using CNC laser processing, then fitted using our patent-pending flexible seal. The seal grips the window frame without drilling, screwing, or any permanent fixings, making it fully reversible and suitable for listed buildings and conservation areas where planning restrictions apply.

Independently tested at the University of Salford Energy House Labs, InGlaze whole pane glazing reduces heat loss by at least 50% — a result verified by the UK’s leading facility for real-world building performance research.

Ideal for

Whole Pane secondary glazing is particularly well suited to living rooms and main bedrooms where heat retention matters most, larger sash or casement windows where Push-In Panes are not the right fit, listed buildings and conservation area properties where permanent alterations are not permitted, and rented properties where reversibility is a requirement.

How it works

Your window is measured and a panel is laser-cut to fit your exact dimensions, including non-standard shapes and sizes common in traditional Scottish properties. The acrylic panel is 3mm crystal-clear, barely visible once fitted, and does not affect natural light or the appearance of your original windows.

The flexible seal accommodates slight variations in frame shape, including frames that have moved or warped over time. It also allows for the natural expansion and contraction of acrylic in changing temperatures without distortion.

Panels clip on and off by hand for cleaning or ventilation. No tools required.
