Magnetite retrofit double glazing system can reduce noise by up to 70% through your existing windows. Magnetic panels provide an air tight seal around the window, just like a fridge door. The system is custom fit for each installation to ensure optimal performance with minimal aesthetic impact for various shapes of windows and doors. Magnetite also provides a thermal barrier by using an optical grade acrylic glazing, which is up to six times more thermally efficient than glass. Enjoy the benefits of double glazing without the hassle of replacement windows.
