A system for controlling the transmission of heat through architectural windows is disclosed in which a magnetized strip is disposed along a major periphery of a frame supporting the window and a flexible window shade is supported adjacent to the frame and is magnetically attracted to the magnetized strip on the frame by a flexible sealing strip secured to the shade. The sealing strip contains a layer of magnetizable particles in a flexible polymeric binder.
