Secondary Double Glazing

For traditional sash windows, or any windows with horizontal bars, the panels slide up and down just like the original sash windows, allowing easy access to the existing window. Highly versatile, glides smoothly, and can be equipped with spring balances or catches to hold the sliding panels open.

Hinged secondary glazing can be attached with butt hinges, friction hinges, or parallel friction hinges. It is excellent for use in hard-to-treat areas like bay windows and other specialised applications. Hinged secondary glazing is the solution when large glass areas require easy access for maintenance, ventilation, or cleaning.

Lift-out panes are ideal for covering large glass areas, staying discreet from the outside, and can be easily removed from the frame for cleaning or ventilation. For situations requiring frequent access, we suggest using alternative systems like hinged secondary glazing.

Fixed units are a cost-effective and efficient solution for minimising noise and heat loss. Designed without any opening mechanisms or subframes, allowing complete removal of glass unit if necessary.
