Frost King EZ Roll Heavy-Duty Patio Door & Large Window Shrink Insulation Film Kit, 84-in x 112-in

The Frost King EZ Roll Heavy-Duty Shrink Insulation Kit is designed to insulate large windows and patio doors, helping to reduce heat loss and improve energy efficiency. This heavy-duty film measures 84 inches by 112 inches, making it ideal for covering expansive windows or sliding doors. The kit features an easy-to-use roll-on application and includes adhesive tape for a quick and secure setup. Once installed, the film tightens when exposed to heat from a standard hair dryer, creating a clear, wrinkle-free seal that blocks drafts and retains heat.
