3M Outdoor Patio Door Clear Insulation Kit – 7 ft x 9.3 ft for Large Windows & Sliding Doors

Improve Comfort with the 3M Outdoor Patio Door Clear Insulation Kit

The 3M kit is designed for outdoor use and helps create a transparent, airtight seal around a large patio door. It combines a clear insulation film with Scotch mounting tape to minimize drafts and keep interior air where it belongs. The result is a streamlined, low-profile setup that stays in place through the season and maintains visibility through the film.

With one door sized at 7 feet by 9.3 feet, this kit is tailored for wide entryways and sliding doors, providing a practical solution for seasonal comfort. The film shrinks tight around the frame to reduce wrinkles, delivering a neat look while you enjoy steady indoor temperatures.

• Roll of Scotch double-sided mounting tape for a secure, airtight seal

Installation Tips and How It Works

Stretch and smooth the film to remove wrinkles as you apply it around the door frame. The included tape creates a strong bond with surfaces and the film, helping seal gaps and prevent drafts. The setup is intended for outdoor use only and should be removed at season’s end.

• Before you start: ensure outdoor temperatures are above 50°F (10°C) for best results
• Trim the film to fit with an extra margin on all sides
• Apply the tape around the frame, uncovering the liner as you go
• Adhere the film to the tape from the top and smooth toward the bottom
• Press firmly and trim any excess film after positioning

Notes for Use

Made in the United States, this kit is intended for exterior doors and works best on surfaced materials. Remove the film and tape at the end of the season and store for future use.
