Casement (Hinged) Secondary Glazing

A versatile, efficient and inexpensive style of secondary glazing that can be side or top hung. This is a strong system with slender sightlines, allowing full and easy access to the outer windows or doors.

With minimal dust ledges and a tight seal, this style of window is often favored by hospitals, surgery rooms or laboratories.

In addition to the single side or top hung units, this style of secondary glazing can also be manufactured as double hung units, being a very good match for double casement windows or french doors.

When opting for this style, clients needs to keep in mind that this style opens into the room. This could cause a problem with blinds or curtains. Special attention also needs to be given to circumstances where the external windows or doors open inward; we need to insure clearance past the secondary units. This is a situation we deal with very often and can be discussed in greater detail when you have a surveyor visit.

All our windows sections are made of aluminum, powder coated white as standard. Frames can however be customised to a different colour or finish to match surrounding décor.

This style of window is available in two different systems:

  1. Slim line, residential hinged system
  2. Heavy duty, commercial hinged system

1. Slim line, residential hinged system:

This is our most popular system and has been specifically designed to sit well with period windows. The aluminum profile is very slim, making sure the secondary glazing blends in perfectly with the external windows.

This system can house a glass up to and as thick as 6.4mm. If your primary concern is thermal insulation, this system is perfect. If your concern is sound reduction, this system is equally as effective – 97% of all our projects for sound reduction is manufactured and installed using this slim system.

2. Heavy duty, commercial hinged system:

Every so often, we are introduced to a project that warrants something a little different. Perhaps the windows or doors are unusually large or the noise is so severe that our surveyors realize that the normal, slim line system will not offer the client the best solution. In these instances, we will look at proposing our heavier, commercial system.

This system is quite specialized and in the past few years, has become increasingly popular.

The profile is of course deeper, but what makes this system special, is it can house a much larger range of glass thicknesses and or be double-glazed.

Of course, this system is substantially more expensive than conventional secondary glazing, but if the property or problem warrants this system as a solution, we will offer it to clients.
