Televent

A system that uses the shade pocket to draw warm or cool air over the window into the ceiling plenum, thus increasing the efficiency of the mechanical system. Commercial Drapery and Blinds LTD., offers many varieties of dual shades comprised of solar shading fabrics with polyester film or blackout fabric.  Shades which use film in combination with other fabrics allow a clear view to the outside while offering excellent protection from sunlight.
