Duck Brand Window Insulation Kit for Large Windows & Patio Doors, 84 in x 120 in, 3-Pack

Overview

When cold weather settles in, energy loss around windows becomes a common concern. The Duck Brand Window Insulation Kit offers an interior shield that helps create a barrier between outdoor air and your living space. The crystal-clear shrink film stays nearly invisible once installed, so your view remains unobstructed while you gain a layer of comfort. Each kit is sized to fit larger openings, with a generous 84 inches by 120 inches of film, and the package includes three insulator kits for flexible coverage on multiple windows or patio doors. For a more comprehensive setup, pair these kits with other Duck Brand weatherization products to maintain cozy interiors throughout the year.

What’s included

• Crystal-clear shrink film (per kit)
• Window kit tape
• Three window insulator kits per package
• Tools needed: measuring tape, scissors, and a hair dryer

The design emphasizes visibility and ease, allowing you to monitor the glass while applying a protective seal that helps reduce drafts when the season turns chilly.

Key benefits

• Blocks drafts and air leaks to help maintain indoor warmth without heavy energy use claims

How to install

1. Clean around the window area and apply tape along the outside edge to secure the boundary.
2. Measure the window and add 2 inches to each dimension; cut the film to fit.
3. Place the film, starting at the top, then work down the sides and bottom for a snug fit.
4. Use a hair dryer to shrink the film and smooth wrinkles for a clear, taut finish.

Size and fit

The kit provides up to 84 inches by 120 inches of window film, offering ample coverage for larger panes and patio doors compared with many alternative kits.

Tips for best results

• For optimal adhesion, ensure the window surface is clean and dry before applying tape and film.
