Lift Out
A practical, cost-effective solution for windows that require occasional access with removable panels










Lift Out
Granada lift-out units offer a practical, cost-effective solution for windows that require occasional access. Each removable panel sits within its own slimline aluminium frame and can be lifted out easily using the Easy Lift Fin.
Face-fixed or reveal-fixed, these units are ideal for decorative or non-opening windows, providing discreet, unobstructed views while enhancing acoustic and thermal performance. Perfect for both commercial and residential applications, lift-out secondary glazing combines convenience, durability, and a clean, unobtrusive design.

Product Case Studies

Sheffield Buddhist Centre
Secondary glazing was installed at the Sheffield Buddhist Centre to improve thermal performance, reduce draughts, and lower the building's carbon footprint. The system sits discreetly within the existing window reveals, preserving the historic frames and complying with listed-building conservation requirements. The installation has increased occupant comfort, particularly in the Great Hall, while protecting the building's heritage fabric.

Compton House, Hay-on-Wye
Secondary glazing was installed at Compton House, a Grade II listed townhouse within the Brecon Beacons National Park conservation area, to improve thermal and acoustic performance across five residential flats. The solution enhanced occupant comfort, reduced noise intrusion, and delivered a cost-effective upgrade while retaining the original single-glazed timber sash windows and preserving the building's historic fabric.
