Heat Mirror Technology
Heat Mirror Technology is a proprietary method of suspending a piece of insulating film between two or more panes of glass, to create a smaller, more easily insulated space. This space allows dense gasses, such as Argon or Krypton to better insulate against UV and IR heat transfer from one side of the glass to the other, while simultaneously allowing the visible light of the sun through, for a brighter, more welcoming space that achieves optimal comfort and efficiency.
