3M 7100043764 Fsk Foil Tape 2.83 Inches Cold Weather

Product Description

The 3M 7100043764 is a foil/scrim/kraft (FSK) laminated tape designed for sealing and facing FSK-faced insulation board and ductwork in HVAC applications. Coated with a pressure-sensitive cold weather solvent acrylic adhesive, it delivers quick tack at normal temperatures while maintaining strong adhesion in low-temperature conditions. The laminated backing combines aluminum foil, a reinforcing scrim, and kraft paper to provide high puncture and tear resistance. HVAC installers and sheet metal technicians use this tape for sealing fibrous ductboard, blanket insulation, and sheet metal duct systems where a durable, long-lasting FSK facing closure is required.

This tape is suited for both residential and commercial HVAC installations where FSK-faced insulation products are present. It performs well in cold weather job site conditions, making it a practical choice for winter construction or installations in unconditioned spaces. The flexible backing conforms to curved and irregular duct surfaces, including fibrous ductboard and insulation blankets, without special tools or application equipment.

Key Features

• FSK laminate backing combines foil, scrim, and kraft layers for use on fibrous and sheet metal ducts
• Cold weather acrylic adhesive maintains adhesion in low-temperature environments
• High puncture and tear resistance for long-term durability in demanding HVAC applications
• Flexible backing conforms to curved, irregular, and fibrous duct surfaces
• Installs without special tools or application methods for fast on-site use

Compatibility

Designed as an OEM-style replacement tape for use with FSK-faced insulation board and ductwork in residential and commercial HVAC systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal workers. Shut down the air handling system before applying tape to ductwork under pressure. Surface preparation is important — ensure the duct or insulation surface is clean, dry, and free of dust or debris before applying the tape for maximum adhesion. Follow local mechanical codes and manufacturer guidelines for duct sealing requirements.
