Secondary glazing adds a slim, internal secondary window or door panel behind your existing frame. It’s perfect for acoustic secondary glazing, thermal comfort, and condensation reduction—without changing the external look of your property. We supply and install secondary glazing across Dorking and nearby towns.

Designed to match your existing windows, horizontal frames slide smoothly open and closed on aluminium runners, helping keep heat in and draughts out.

This option is ideal for traditional casement windows, as the secondary glazing swings open on a small hinge, in line with the mechanism of the window behind it.

Perfect for box sash windows, the panels in these vertical sliding frames move easily up, down and can tilt inwards to provide easy cleaning access to the original window.
