Above we have provided a video showing us installing a new vertical slider window for an existing vertical counterbalanced slider leadlight window.

Double glazing casement, sash & vertical sliding windows with retrofitted Vertical Slider window for double glazing

Vertical Sliding Window Secondary Glazing

The full-length handles found on the bottom of each panel are used to control the retrofitted vertical sliding windows.

The spring balances on the side of the outer frame allow the panels to slide to whatever position as needed and keep them there.

For vertical slider windows or vertical sliding secondary glazed windows, we provide twin Polypropylene Weatherpiles for double sealing.

In addition to vertical slider aluminium or wooden windows, we can retrofit secondary glazing to casement or sash windows using our retrofitting system.

So, if you require soundproof sash windows, casement windows or vertical slider windows, secondary double glazing is a very cost effective solution compatible with existing casement, sash or vertical slider windows.
