Hinged Aluminium Secondary Glazing

Hinged Secondary Glazing

Our hinged secondary glazing can either be butt hinged, friction hinged or parallel friction hinged, each has it’s own advantages and disadvantages. Generally hinged secondary glazing lends itself to use in hard to treat areas such as bay windows and other specialist applications. It is ideal for large glass areas where quick and easy regular access is required. i.e. for maintenance, ventilation or cleaning.

Butt hinged units open to around 150° giving a large clear opening for full access to the existing windows. Friction hinged units open to around 65° providing a large opening. The friction hinges allow the panel to be held in any given position, regulating ventilation. Parallel hinged or PIP™ secondary provides a restricted opening for controlled, secure ventilation. Hinged units can also be combined with Lift Out units, making them perfect for specialist applications.

Glass Options

Our standard glass for our secondary glazing is 4mm clear float glass. We have a huge variety of glass available for our secondary glazing and it is possible to tailor your secondary glazing to your individual requirements. You can specify glass for improved sound insulation, thermal performance or security. Different thinnesses of glass are available for greater thermal and sound insulation. See examples of the different glass we can offer below:

Thickness Glass Properties
4mm Float Glass Can expect good improvement in sound and heat insulation. (a.k.a. Annealed Glass)
4mm Obscure / Patterned / textured Glass Specified for aesthetics and privacy (e.g. in a bedroom or bathroom). Read More...
4mm Toughened Glass Same as float glass with added safety and security.
6mm Float Glass For better performance in sound and heat insulation when compared to 4mm float. Has greater strength than 4mm glass for use in larger panels. (a.k.a. Annealed Glass)
6mm Toughened Glass Same as 6mm float glass, but provides added safety and security.
6.4mm Laminated Safety Glass For superior sound and heat insulation and far superior safety and security.
6.8mm Acoustic Glass For a dramatic improvement in sound proofing / noise insulation.
