Quick, hassle free installation

What is a secondary glazing installation process? Secondary glazing is installed to the interior side of your window, creating little to no mess. Most installations are completed within the hour. Secondary glazing can be installed to reveal the window or can be fixed to the face of the primary window.

Measuring your window for installing secondary glazing is to select the design that complements your existing primary window. Select a design that you do not add additional site lines and can give you access to your primary window for maintenance, cleaning and ventilation.

It is manufactured from aluminium and powder coated, to give a durable and aesthetically pleasing finish. You may on occasion have to wipe the aluminium down with a damp cloth to de-dust. Cleaning the glass is no different than other glass products.

Reduction in heat loss and sound pollution

Installation of secondary glazing boasts many unique benefits including 80% reduction in sound and 65% decrease in heat loss. Installing secondary glazing will require a small air cavity that acts as the insulation between your primary window and the glazing.

An experienced tradesperson can install secondary glazing in an hour. The products we use are supplied as standard with a hardwood subframe – the subframe has two purposes; enhances the rigidity of aluminium window for ease of installation and acts as a thermal barrier.

Face Fix and Reveal Fix

Secondary glazing can be installed using either reveal fixing or face fixing. Each installation type will increase either the thermal or acoustic performance of your home. It is advised to have your secondary glazing installation done by a professional to ensure you receive the following benefits.

Face fix is recommended to increase thermal performance and should be installed no more than 80mm away from the primary window. This is installed to the internal facing of your primary window, no more than 80mm away.

Reveal fix achieves optimum, acoustic performance. We recommend acoustic glass where the secondary glazing is installed with a 150mm to 200mm air cavity glass to glass. This secondary glazing option is installed within the window reveal to enhance acoustic performances up to 80%.

Benefits of Secondary Glazing Installation

Noise Reduction

Installing secondary glazing can help to prevent exterior noise pollution such as passing traffic or trains from being a nuisance. Install a 6.8mm acoustic glass with the secondary glazed units with an air cavity of 150mm to 200mm glass to glass.

Thermal Performance

Secondary glazing installations will decrease heat loss through your primary window by 65% – we advise the 6.4mm low E glass. The low-E glass has a transparent coating that is thinner than a human hair, explicitly designed to reflect heat into your home.

Increased Security

Secondary glazing can’t be opened from outside – so it adds an extra barrier of safety to your home. This glazing offers an affordable, discreet, highly effective solution to protect your home further should an attempt to break the window happens.

Stop Condensation

Installed with a trickle vent that minimises condensation. Well fitted, secondary windows provide a completely secure and sealed solution to stop condensation from occurring. Protecting the window from condensation, while retaining insulation.

The Benefit of the Subframe

Granada secondary glazing is manufactured and supplied with a timber subframe. The wooden subframe acts as a thermal barrier to prevent the cold from the fabric of the building onto the aluminium. This further helps reduce condensation, as the temperature of the building fabric does not cool the temperature of the aluminium frame and glass.

Conservation Areas

Secondary glazing can often be installed within conservation areas, Grade one and two listed buildings. These styles of buildings often have regulations for replacing windows with traditional double glazing. This makes secondary glazing installation a popular choice among homeowners.

As listed buildings and conservation areas have regulations for replacing windows, it is often advised to get a building consent for the installation of secondary glazing. The English Heritage regularly recommends the secondary glazing installation as opposed to double glazing.
