This secondary glazing option is perfect for heritage properties and modern buildings alike. Vertical sliders have a tilt option that enables both panels to individually pivot inwards for easy access and cleaning.
Ideal for when you’re unable to replace sash windows with modern double glazing in a listed or heritage property and wish to maintain sightlines of original windows. Secondary glazing sash windows are fitted discreetly on the inside giving you all the advantages of modern living without impacting the façade. They’re also lockable for additional security.
For modern properties, our sash window secondary glazing offers a vintage look. This enhances your property stylistically while preserving the modern comforts of 80% noise reduction and 65% extra thermal insulation.Get a free quote
Secondary Glazing for Sash Windows specification
Designed specifically for sash windows as well as other vertical sliding units, or where regular hinged panels are not suitable. Just like a traditional box sash, our vertical sliding units feature two sashes, one above the other, retained within an outer frame. They are supported by robust spring balances for ease of motion and weight support and fitted with brass rollers of a smooth sliding action.Get a free quote
Special tilt-in feature
Each secondary sash can be independently released from the outer frame. It comes with restrictor arms as standard which, once removed, allows the unit to be be pivoted inwards by almost 180° making it easy to access all frames. The outside of the glass will be as easy to clean and maintain, without compromising either sightlines or the overall style of your windows.
