M-D SHRINK AND SEAL INDOOR WINDOW KIT - 5 WINDOWSClear interior shrink-film insulation kit for sealing drafty windows for the heating season. The film mounts to the trim with the included double-sided tape, then shrinks tight with a household hair dryer to a wrinkle-free, see-through finish. The trapped air pocket between the film and the glass cuts cold-air infiltration, knocks down window condensation and frost, and adds insulating value to single-pane and aging double-pane windows without changing how the window looks from across the room.
- Covers up to five standard windows
- Film size: 200" x 64" (clear polyethylene)
- Includes double-sided mounting tape sized to the film
- Shrinks tight with a household hair dryer for a wrinkle-free, see-through finish
- Reduces drafts, window condensation, and frost on cold glass
- Removes cleanly in spring without damaging painted trim
Installation: Wipe the inside face of the window trim clean, press the tape around the full perimeter, peel the tape backing, and stick the film to the tape leaving a slight overlap on all sides. Run a hair dryer in slow passes a few inches off the surface; the film pulls taut as it heats. Trim the excess with a sharp knife.
Tip: The 5-window kit is the most cost-effective option per window if you are doing a whole room or floor of a house. Cut the film to the largest opening first, then use the leftover for smaller windows - you cannot piece small sections together once the tape is down, so plan the cuts before peeling the tape backing.
