Vertical Sliding Secondary Glazing

This secondary glazing option is perfect for heritage properties and modern buildings alike. Vertical sliders feature a tilt option that allows both panels to pivot inward for easy access and individual cleaning.

This is ideal for when you cannot replace sash windows with modern double glazing in a listed or heritage property and wish to maintain the 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's aesthetic while preserving the modern comforts of 80% noise reduction and 65% additional thermal insulation.

Explicitly designed for sash windows and other vertical sliding units, or where regular hinged panels are unsuitable. 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 for a smooth sliding action.

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, allow the unit to be pivoted inwards by almost 180°, making it easy to access all frames. The exterior of the glass will be easy to clean and maintain, without compromising sightlines or the overall style of your windows.

Customised:

We offer a range of 4mm–8.8mm glazing for thermal performance and reduced noise transmission within your property. You can decide whether you prefer face-fixed or reveal-fixed, and we offer over 200 RAL colours to match the look of your existing windows. The additional locking facility provides extra security, and our 10-year guarantee means complete peace of mind. It remains one of our most popular options for conservation area buildings and is gaining favour even in more modern developments.
