  • Double-stick design bonds film securely to frames

  • 1/2-inch width fits standard window casings
  • Indoor formulation resists interior temperature changes
  • Ready-to-peel liner speeds up application process

Double-stick tape for interior window film

This 3M 2145C tape is designed for indoor use with heat-shrinkable window film kits. The 1/2 inch by 500 inch roll applies to frames and casings to create a secure, airtight bond between the glass, tape, and film. It suits homeowners sealing drafty windows for seasonal energy savings.

Ready-to-peel liner simplifies installation

The liner removes cleanly so you can position the film accurately before shrinking. Adhesion is formulated for interior surfaces only; outdoor exposure will degrade the bond. The fixed 500 inch length limits coverage to a specific number of standard windows.

Fifty linear feet covers multiple frames

One roll handles several average window perimeters with headroom for trimming and overlap. Very large picture windows or full patio doors may require a second roll to complete the seal. The tape is not structural and cannot compensate for damaged or rotting frame surfaces.

Questions about this item

Which roll size should I pick for a standard window frame?

The 2145C tape comes in a single 500-inch roll at 1/2 inch width, designed to cover multiple standard frames in one length.

How does the 500-inch length translate when sealing a typical double-hung window?

At 500 inches total, the roll provides enough double-stick tape to seal the perimeter of several average double-hung windows with a continuous airtight bond.

What surfaces does the indoor-rated adhesive bond to on a window frame?

The indoor formulation bonds directly to wood, vinyl or painted window frames and casings, creating the airtight seal required for 3M heat-shrink interior window films.
