3m Indoor Window Insulator Kit - 5 pack

For indoor use only. Stops cold drafts and helps prevent frost buildup. Acts like an extra storm window. Reduces heating costs and saves energy. Part of 3M's line of energy-saving products, this kit includes window insulation film and a roll of double-sided mounting tape to create an airtight seal. Stretching the film removes wrinkles for a transparent view. This version of the 3M indoor window insulator kit enables you to insulate five 3-foot-by-5-foot windows.
