3M Indoor Window Insulator Kit: 7 ft. x 19.7 ft. / 1 window (Clear)

3M Indoor Window Insulator Kit provides powerful window insulation that protects against air leaks in both directions in an easy to install all-in-one kit. Inefficient or dated windows tend to both let cold air in and hot air out. In the wintertime, this can lead to dramatic increases in energy costs as well as even discomfort due to the inability to regulate the air temperature in your home. This makes window insulation a no brainer for the fall and winter seasons. Window insulation also cuts down on condensation and works to prevent frost buildup, so your windows can stay clean and enjoyable regardless of the time of the year. The kit includes a powerful double-sided tape that is well suited to maintain its adhesion all season long and 10 square yards of crystal clear insulating film. For example, that is enough material to insulate five 3-foot x 5-foot windows. Country of Origin: United States.
