Skylight window protection and noise suppression. In addition, offer protection for the glass itself. The screen is a Teflon coated fiberglass with a 300 lb per square inch bursting strength. ICE and SNOW will not build up except in extreme cases , and there is little to no light loss. Just remove the screen by gingerly separating it from the window frame as the system uses Velcro.
Installation is simple and can be done within an hour.
