How Magnetite works

Magnetite window panels are a unique interior mounted insulating panel that attaches and seals magnetically around the entire perimeter of your window, no matter it's size or shape. Magnetite uses magnets, optical-grade acrylic and dead air space. These technologies are used in ways that we are all familiar with:

  • We get milk from our refrigerator and take for granted that it will be cold. However, it stays cold because of the magnetic seal in the door. This magnetic seal is the barrier that keeps the cold in and the hot out.
  • We fly home to see our parents and gaze out the window or enjoy the quiet interior of the airplane. We forget that it's -40°F outside and wind is whipping by at 300+ mph. Seat 11A is quiet and comfortable thanks to the optical-grade acrylic that lets us see out and protects us from the elements.
  • We grab our coffee or tea, head to the car, and don't think twice about not burning our hand on the travel mug. Our hand stays safe and our drink stays piping hot because of the dead air space between the inner and outer layers of the mug.

When these technologies are combined, the result is a product that seals window air leaks, makes homes and businesses quieter and makes windows more energy efficient.

Why you need Magnetite

Keep your view

Like the lenses in your glasses or the contacts in your eyes, our optical-grade acrylic is clear. Our acrylic panels won't affect the aesthetics of a window (from  inside or out), won't affect the visibility through a window, and won't yellow over time.

Magnetite insulated window panels are an ideal solution for historic buildings.

Keep your windows

Truly increasing thermal performance and energy efficiency of a window doesn't require replacing it. If your window isn't broken, a double glazing such as Magnetite has been proven to be a better alternative in both cost and efficiency comparisons. The Magnetite interior acrylic panels can be retrofit to just about any window, door, skylight, arch, or sliding glass door with no messy construction.

Increase your efficiency

Glass is the greatest source of energy loss in any building, with up to 40% occurring through the windows (according to the Dept. of Energy). Adding Magnetite's acrylic panel, that is 8-times more thermally efficient than glass, along with a dead air space due to the magnetic seal creates a window system that is up to 115% more efficient.
