3M 7100043752 Aluminum Foil Tape 2.83 in X 50 Yd Cold Weather

Product Description

The 3M 7100043752 is a dead-soft aluminum foil tape with a cold-weather pressure-sensitive acrylic adhesive, designed for vapor sealing on HVAC ductwork and exterior insulation materials. The aluminum backing is high-strength yet flexible, conforming to curved and irregular surfaces including fibrous duct board and sheet metal duct. The acrylic adhesive maintains bond strength at temperatures well below freezing, making this tape a reliable choice for installations in unconditioned spaces, cold climates, and winter job-site conditions. Each roll measures 2.83 inches wide by 50 yards long.

This tape is used in residential and commercial HVAC applications where duct sealing, insulation jacketing, and vapor barrier work are required. It is appropriate for sealing longitudinal and circumferential seams on fibrous glass ductboard, wrapping duct insulation on sheet metal systems, and patching foil-faced insulation on exterior mechanical systems. The hand-tearable construction allows field technicians to cut and apply the tape without scissors or a dispenser, reducing installation time on tight schedules.

Key Features

• Dead-soft aluminum foil backing conforms to curved, irregular, and fibrous duct surfaces
• Cold-weather acrylic adhesive bonds at temperatures well below freezing without losing tack
• Hand-tearable — no tools or dispenser required for field installation
• High puncture and tear resistance for long-term durability in demanding environments
• Suited for vapor sealing on ductwork and exterior insulation jacketing
• Roll format: 2.83 inches wide x 50 yards long

Compatibility

Designed for vapor sealing and insulation seam applications on fibrous glass ductboard, sheet metal duct systems, and foil-faced exterior insulation materials in HVAC installations.

Installation Notes

Applied by HVAC technicians and insulation installers working on duct systems and mechanical insulation. Clean and dry all surfaces before applying tape to ensure maximum adhesion. In cold-weather conditions, press tape firmly across the full width of the seam to activate the pressure-sensitive adhesive. Follow local mechanical codes and manufacturer insulation specifications for approved sealing methods on duct systems.
