Twin Draft Guard€s Indoor Extra Large Window Insulation Kit, Energy Saver

The double sided tape is really lousy. The side that sticks to the wall (frame) isn't tacky enough to stick! I followed the instructions, cleaned the area with alcohol, let it dry completely. I applied the tape, pressing firmly. The instructions say wait 15 minutes to insure the tape is sticking. I waited, but it was already coming away from the wall! The other side of the tape (when you peel of the paper backing and attach the plastic IS very sticky).I would not buy this product again.
