With one pane of glass, hinged units will retain the character of your home whilst keeping it peaceful, warm and secure. For homes with poor thermal insulation, hinged secondary glazing will provide a significant increase in thermal insulation as it is available with a double-glazed glass panel.

Hinged secondary glazing offers many benefits including a reduction in noise entering your home, enhanced thermal installation and additional security. Where home security is a concern, hinged units are manufactured with secure multi-point locking. Our multi-point locking system ensures the glazed panel locks securely in place and pulls the panel tight to the outer frame, this creates a seal that will decrease heat loss.

With no transoms or mullions to spoil the view, our hinged secondary glazing windows are a truly unobtrusive secondary glazing system. They offer full access to your primary window allowing you to maintain and clean. The glazed panel opens into the room, making it easy to clean the back of the secondary glazed system. Hinged units can be manufactured with the hinges positioned left, right, or top-hung to match the style and function of your primary windows (most commonly the hinges are placed on the left).

You can install our hinged secondary glazing system to any style of window from casement to traditional box sash. The heritage hinged unit is the only secondary glazing product that is available with an energy-efficient double-glazed unit, this is beneficial to homes that suffer from low thermal insulation.
