3M Company 2145C Window Film Mounting Tape

Product Description

The 3M COMPANY 2145C is an interior-grade window film mounting tape designed to secure window insulation film to interior window frames and moldings. Measuring 0.5 inches wide by 500 inches long, this tape provides a firm, lasting bond without damaging painted or finished molding surfaces. It is intended for use with 3M Indoor Window Kits and similar interior window insulation systems. HVAC installers, weatherization contractors, and building maintenance technicians use this tape when installing seasonal window insulation to reduce drafts and improve thermal efficiency in residential and light commercial settings.

This tape is suited for interior window film installations in residential homes, apartments, and light commercial buildings. It is applied directly to window moldings and frames as part of a window insulation kit setup. The 500-inch roll length allows a single roll to cover multiple windows in one installation session, reducing the need for frequent roll changes on larger jobs.

Installation Notes

Installation is typically performed by HVAC technicians, weatherization specialists, or maintenance personnel. Clean and dry the window molding surface thoroughly before applying tape to ensure proper adhesion. No special tools are required, though a straight edge or roller can improve contact and bond strength. Follow applicable building weatherization guidelines when installing window insulation systems.
