An insulating shade including a channel-type frame which is designed to be permanently installed on the prime window frame. The shade assembly which is mounted in the frame includes a pair of rollers which are geared together so as to rotate simultaneously and simultaneously either take up or play out the shade material. The rollers with the shade are supported on bearing plates which in turn are hung on spring brackets that snap into the channels permanently secured to the window frame. A cord operated pulley carries a gear which in turn drives the two rollers so as to raise and lower the shade. Weather stripping is secured inside the channels of the frame, which cooperate both with the sides of the shade itself and the weighted roller at the bottom of the shade to prevent cold air from flowing about the shade.
