Magnetite Retrofit Double Glazing

Improve Thermal Comfort and Reduce Noise with Magnetite

Double glazing can dramatically improve the comfort of a room, home or building by creating a comfortable, stable indoor temperature, and reducing the noise. Magnetite allows existing windows to be converted to a double glazed system, providing all the benefits of double glazing without requiring you to replace your existing windows. The Magnetite retrofit double glazing system is designed and tested to work with your existing windows, doors, skylights and glass areas.

Why Choose Magnetite

Noise Reduction

Magnetite can reduce up to 70% of noise through windows or doors, delivering the peace and quiet you deserve.

Thermal Comfort

Magnetite can reduce heat loss or heat gain through your windows or doors, creating year-round thermal comfort. Magnetite in combination with Solartite will transform your standard, generic glass window into a high-performance glazing system.

Energy Efficiency

Magnetite improves the performance of your windows and doors, keeping your home or office comfortable all year round while reducing heating and cooling bills.

How Magnetite Works

Installation of a discreet Magnetite subframe allows a clear optical grade acrylic panel to attach inside the existing windowsill, using continuous magnetic channels to ensure a secure and airtight seal around the window. The magnetic seal ensures that when the Magnetite panels are in place, the double glazed window insulation system has the lowest air infiltration rate of any operational window. This seal creates an air cavity between the existing window and your Magnetite panels.

As with traditional double glazing, the air cavity acts as an insulation barrier against noise and temperature. Depending on the configuration of the existing window, we can adjust the size of the air cavity to maximise thermal insulation, acoustic insulation or both.

The Magnetite subframe is foam PVC and acts as a thermal break between the existing window and the Magnetite secondary system. This sub-frame also allows Magnetite to attach to any existing window frame – timber, aluminium or steel. The acrylic glazing panels used by Magnetite are up to six times more thermally efficient than glass. Solar control films may also be applied to windows requiring a reduction in radiant heat. We apply a film to the inside layer of the existing glass. By having the film on the inside of the existing window, we can reflect the heat before it enters the air cavity for maximum performance.

Magnetite comes in three models: the Magnetite Classic – removable panels, ideal for double hung and timber windows, Magnetite Easyglide, ideal for sliding windows and ease of use and Magnetite Slider for larger windows and sliding doors.

Noise Reduction Technical Data and Results

Proven Results

Noise pollution is one the biggest problems faced in the cities today, particularly in a high-density living. Unwanted noise can be responsible for sleep loss and lack of concentration. This can lead to a deterioration of health through increased stress levels, headaches, high blood pressure and loss of hearing.

Noise penetrates windows through leaky seals or vibrations through the window structure. To reduce noise, a window should minimise air infiltration, hold enough weight to limit vibration and allow a large air cavity. This cavity, or air gap, is the key to secondary glazing.

Expert Advice:

CSIRO Research by John Davy shown an air cavity can effectively enhance sound insulation performance. The larger the air cavity the more noise the window system can reduce. Results show a wide air gap of 100-125mm will improve sound insulation by an average of 7dB(A) more than windows with a narrow gap of 8-13mm.

Single Glaze 6mm	6	0	27
Double Glaze Narrow Gap	9-12	8-13	31

The human ear is less sensitive to low frequency sound. According to a study released by the CSIRO, the human ear needs a change of 3dB to detect a difference in noise levels and the human ear perceives a change of 10dB as a doubling or halving of the noise level.

If you double the thickness of glass in a window the noise level will decrease by 3dB the least amount possible to make a difference. If the glass is laminated there is no perceived difference in noise reduction.

National Acoustic Laboratory Testing:

Working with the principles of noise transfer, Magnetite® and Soundtite are designed for high performance, which is achieved by combining air tight seals with the ability to maximize an air cavity and the flexibility to vary glazing thickness to suit. Magnetite® is excellent at reducing general noise such as busy roads, commuter trains and noisy neighbours. Whereas, Soundtite works well to combat low frequencies noise such as garbage truck, freight trains or airplane during take-off and landing.

*The Weighted Sound Reduction Index (Rw) is a measure for sound insulation performance of a single building element such as windows. The higher the Rw rating, the better the sound insulation.
