Research by Dr. John Davy at the CSIRO has shown that secondary windows will reduce more noise than single glazed windows or even traditional double glazed units.
This is due to the large buffering air cavity between two windows. The larger the air cavity the more noise the window system can reduce.
Magnetite is able to utilize these facts to the advantage of the end user. Our magnetic seals provide one of the lowest air infiltration rates of any operational window.
Our slim extruded framing allows us to maximize the air cavity obtained for all window types.
This allows us to use acrylic glazing, which is safer and lighter than glass in our window system.
Whereas traditional double-glazing uses thick glass and a narrow air cavity, Magnetite is able to use safer, more manageable acrylic with a larger air cavity.
Magnetite is excellent at reducing noise in the frequencies from 400Hz to 20,000Hz. This is ideal for reducing noise from busy roads, commuter trains, and noisy neighbors.
*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.
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.
Testing has shown that the addition of Magnetite panels can reduce the noise level through your window by up to 70%.
