Hinged windows can be installed with any style of original window from casement to traditional box sash. Our secondary glazed panels open into the room with hinges positioned on whichever side you wish, or can hung from the top should you require. There is also a choice of single or double-glazed panes for enhanced acoustic performance.
The multi-point locking system ensures the glazed panel locks securely in place, pulling the panel tight to the outer frame which creates a seal that locks in the heat of the room and provides 80% noise reduction and 65% extra thermal insulation. All our hinged units are manufactured with secure multi-point locking as standard.
With no transoms or mullions to spoil the view, our hinged secondary glazing windows are a truly unobtrusive secondary glazing system for heritage and modern properties alike. Full access allows for maintenance and cleaning of both secondary glazed and existing windows.Get a free quote

Hinged Secondary Glazing FAQ's
What are the benefits of Hinged Secondary Glazing?
Hinged secondary glazing creates a picture frame around the primary window which features no additional sightlines. This gives the homeowner the advantage of improving the thermal and acoustic performance of their existing window, without having to damage the existing sightlines.
What hinged secondary glazing options are available?
We offer two distinct variations of our hinged secondary glazing – the heavy duty and the slimline. Our heavy duty hinged unit is designed for larger glass expanses and features a robust handle section paired with espag handle. Our slimline hinged unit features a much sleeker frame and a unique handle section that sits flush against the frame.
Is hinged secondary glazing as good as double glazing?
Hinged secondary glazing outperforms double glazing in the majority of cases from a noise cancellation perspective. For additional noise reduction and thermal insulation, our heavy duty hinged unit can be fitted with 28mm argon filled double glazing, providing homeowners with the best of both worlds.
How much does hinged secondary glazing cost?
The cost of hinged secondary glazing will vary depending on a number of factors. Whilst it’s difficult to give an estimate without correct measurements and glass requirements, secondary glazing in general often proves to be a more cost-effective solution than traditional window replacement.
