3M Interior Patio Door Insulator Kit 2144W-6 Clear 84 x 112 Inch

Interior Patio Door Insulator Kit

The 3M Interior Patio Door Insulator Kit 2144W-6 provides a clear film barrier that stops cold drafts and helps prevent frosty windows on indoor patio doors. The kit covers an area of 84 by 112 inches and uses double-stick tape for secure attachment to aluminum, painted wood, or vinyl-clad molding.

Homeowners sealing a single large door

This kit suits homeowners who want to insulate one large patio door without specialized tools beyond scissors and a hair dryer. Renters or owners of smaller windows should look at something else because the film dimensions and tape length are sized for a single door opening.

Double-stick tape and hair-dryer installation

The included 1/2 inch by 13.6 yard double-stick tape eliminates the need to buy adhesive separately. Applying heat from a hair dryer removes wrinkles from the film, leaving a smooth, glass-clear finish that maintains visibility through the door.
