Comments about 3M Indoor Window Insulator Kit (2120c):
This is an effective product to reduce heat loss on any window at very low cost. Big money saver! It works by creating an invisible, stagnant air gap between the room and the window glass. This is NOT a film that you apply to the glass, but an insulating air gap; do not confuse the two. I think other retailiers do, and they do not sell this product. Buy here and don't miss out on one of the most effective low-cost energy-savers available!
