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

Hinged Secondary Glazing
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.

Vertical Sliding Secondary Glazing
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.
