Description

About our horizontal sliding secondary glazing

Made-to-measure horizontal sliding aluminium secondary glazing, fitted on the inside of your existing window. Panes slide sideways in the frame, so you can open the secondary glazing for ventilation or to reach and clean your original window. Well suited to wider windows.

Because it sits inside the existing window, your original frames stay in place, which makes secondary glazing a practical choice for period and listed properties.

Horizontal sliding secondary glazing is a versatile choice for wide windows, casement windows and modern windows in homes, offices and hotels. With acoustic laminated glass it is a practical way to cut traffic and street noise. See our guide to acoustic secondary glazing. On wide sash windows it lets you reach the sash behind easily.
