The 1/2" EcoTrack Single Cell Blackout Shades system maximizes the energy efficiency of the single cell blackout cellular shade by closing the gap between the side of the shade and the window. The new EcoTracks are attached to the window casings with magnets and can be easily removed for window cleaning. The newly developed clear edge seal is placed between the shade and the track to help create a tight seal. The dual seal system helps to minimize heat loss and save energy dollars. Just as zippering an open coat in the winter makes a big difference in blocking out the cold, the EcoTrack maximizes the energy savings value of a cellular shade by blocking the air gap. As with all of our products, these shades come with a limited lifetime warranty.
