Duck Max Strength Heavy Duty Window Kit 62 in x 126 in Clear 3 pieces

Window insulation kit for drafty homes

The Duck Max Strength Heavy Duty Window Kit supplies three pieces of clear shrink film sized at 62 in by 126 in. It is designed for homeowners who want to reduce heat loss through windows during cold weather. The puncture-resistant film creates an added barrier between outdoor air and the indoor space. Installation requires only a hair dryer and scissors.

Upgrade from standard window film

This kit replaces thinner standard window insulation films with a rolled film that is two times thicker. The jump is worth it for high-traffic rooms or pet-friendly households where durability matters. The easy-to-use roll eliminates the need for measuring before application. Users simply cut the film to size after positioning it.

Sustained performance through the season

Once applied to clean, dry surfaces such as painted wood, aluminum, or vinyl, the film maintains its seal for the heating season. The crystal-clear material preserves visibility while blocking drafts that drive up heating costs. Removal is straightforward when warmer weather returns. The heavy-duty construction resists punctures from daily household activity.
