What is Secondary Glazing?

Secondary glazing features the installation of a slimline, discreet aluminium panel fixed either within the reveal, or to the face, of the existing window. Effective secondary glazing should be barely visible to the naked eye, whilst bolstering both the thermal and acoustic performance of the primary window. An independent unit that operates separately from the existing window, secondary glazing is an ideal solution for properties where window replacement is not an option.

What are the main types of secondary glazing?

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.

Fixed Secondary Glazing

Our most simple secondary double-glazing product is typically used when the area for fixing into, is minimal. Once installed, the glazed panel cannot be removed.

A fixed secondary glazed window is an independent window that is permanently fitted on the inside of an existing door or window. It’s ideal for when space is limited, or when minimal access to the primary window is required. For this reason, our fixed units are incredibly popular in large-scale commercial projects.

Turn button releases are optional to enable removal for cleaning and maintenance if required. Available in several different styles as well as single or double-glazed aluminium profiles, there are a number of configurations to choose from.

Lift Out Secondary Glazing

Glazed panels are held in place with a slimline, robust aluminium outer frame. Panels are simply lifted out of the outer frame to give access to the existing window.
