Secondary Glazing

Our secondary glazing has all been designed to be strong, reliable, and unobtrusive when installed. The process involves fitting a discreet internal unit in addition to your existing window. This provides a cost effective and efficient way to insulate and soundproof your windows, and is the preferred method for use within Listed Buildings and conservation areas.

Secondary glazing involves the installation of a slimline glazed unit made of aluminium profile inside your existing windows. Depending on the type of existing window there is a large selection of colours and styles to choose from. These styles include;

Horizontal slider

Suitable for a variety of window types including casement and fixed. The sliding units open from side to side.

Hinged Unit

This option opens like a door and is available with multipoint locking systems. It has no mullions or transoms so will provide the most unobstructed view. Most suitable for casement windows and sash windows.

Lift Out Unit

This option has the ability to easily remove the frames when required such as for cleaning or ventilation. Best for windows that don’t require much access.

Vertical Slider

Best for sliding sash windows and these units open top to bottom, also available with a tilt in function.

Fixed Unit

As it sounds a fixed unit is a permanently fixed on the inside of an existing window, best option when space is limited.

Bespoke Options

Secondary glazing units can be custom made for your specific window such as an arched window or a non standard shape.

• Noise Reduction - Secondary Glazing is one of the best options for noise reduction, outperforming many glass options. It can reduce noise levels by an impressive 80%. Perfect for noisy roads or homes near trainlines or flightpaths.
• Thermal Insulation - Secondary Glazing can act as an insulator between your existing window and the unit due to the small gap. This layer of air between the two can reduce heat loss by up to 65%. ­­­­­­
• Listed Buildings & Conservation Areas - Secondary Glazing is the ideal solution if your property is a listed building or you live in a conservation area. It provides all the thermal and acoustic benefits you’d expect from a 21st century window system, without damaging the unique aesthetics of the primary window.
• Increased Security - Secondary Glazing can add an additional layer of security to your windows. It's extremely difficult to open from the outside and the frames are made from durable, high quality aluminium.
