Energy Efficient Windows

Convert Your Existing Windows into Energy-Efficient Windows

Double glazing existing windows can improve thermal insulation, making your windows more energy efficient. This means you can save money, by reducing energy bills for heating or cooling. Magnetite retrofit double glazing convert your standard, single glazed window into energy efficient windows without having to replace the existing windows.

Magnetite’s solutions will create energy efficient windows in your home or office by enhancing your existing windows performance. Magnetite, retrofit double glazing transform your window into the best energy efficient window for winter performance and can be enhanced with the addition of Solartite, high performance window films, for optimal summer performance.

6-Star Thermal Improvement

Magnetite has been independently tested by WERS (Window Energy Rating Scheme) to demonstrate an improvement in the window thermal performance by over 70%. Converting your existing windows into energy efficient windows using Magnetite’s solutions can dramatically reduce your heating and cooling bills. The magnetic seals eliminate draughts and help maintain a more comfortable and stable indoor temperature reducing the reliance on artificial heating or cooling. This will bring a faster return on investment, allowing you to lower your overheads and reach your savings targets faster.

Magnetite has been designed and developed with government assistance to help improve the sustainability and reduce the carbon footprint of Australia’s existing building stock. Our retrofit double glazing is a sustainable investment with no fixed term that offers a range of energy and environmental benefits. We take our commitment to retrofitting and the built environment seriously. Magnetite is a proud member of Ecospecifier, WERS, and has a Green Star accredited professional on the team to provide an industry perspective to our clients. Check out our recent projects on how Magnetite creates building efficiency through the best energy efficiency windows.

Our Products

Magnetite®

Retrofit double glazing for acoustic and thermal insulation

Our proven magnetic secondary glazing system enhances the performance of your current windows, doors, skylights, and glass areas by creating an insulating air cavity. This barrier reduces noise and stabilises indoor temperature, resulting in a more comfortable environment for rooms, homes, and buildings.

Sealtite

Acoustic and weather seals

Enhance the insulation of your home or office with our selection of acoustic and weather seals. These seals improve the performance of your existing windows and doors by using draught-proofing strips that are suited to any style. Sealtite weather seals not only reduce noise levels but also enhance thermal comfort, all while being custom fit for immediate soundproofing benefits. Enjoy easy operation with this effective solution.

Solartite

High-performance window film

Solartite works in conjunction with Magnetite to offer a solution for existing windows that need to reduce radiant heat. This way, you can avoid feeling too warm in your own home. Solartite is applied to the inner layer of the glass, making your living or working space more comfortable without having to increase the use of air conditioning. By reflecting heat before it enters the air space, Solartite ensures optimal performance.

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.

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.
