3M 7100169857 Aluminum Foil Tape 2.5 in 49.98 Yd Cold Weather

Product Description

The 3M 7100169857 is a cold-weather aluminum foil tape designed for duct sealing, heat shielding, and light-reflecting applications in HVAC systems. Built on a nominal 1.8 mil aluminum foil substrate, it uses a pressure-sensitive acrylic adhesive formulated to bond in temperatures as low as -10 degrees F. The flexible foil conforms to curved, irregular, and fibrous surfaces, making it suitable for both fibrous ductboard and sheet metal duct assemblies. It is hand-tearable and requires no special tools or applicators, which supports fast field installation by HVAC technicians and sheet metal workers.

This tape is suited for residential and light commercial HVAC applications where duct sealing integrity and low-temperature adhesion are required. It performs well on fibrous ductboard, sheet metal ducts, and other irregular surfaces encountered during installation or service work. General-purpose heat shielding and light-reflecting tasks are also within its rated scope. Each roll measures 2.5 inches wide and 49.98 yards long, providing substantial coverage per roll for both new installations and repair work.

Key Features

• Nominal 1.8 mil aluminum foil construction for durability on fibrous and sheet metal duct surfaces
• Cold-weather acrylic adhesive rated for adhesion down to -10 degrees F
• Flexible foil conforms to curved and irregularly-shaped surfaces
• Hand-tearable design requires no cutting tools for field use
• Easy-release liner for clean, efficient application
• Suitable for general-purpose heat shielding and light-reflecting applications

Compatibility

Designed for use on fibrous ductboard and sheet metal ducts in HVAC systems; also suited for general-purpose heat shielding and light-reflecting applications where a flexible foil tape with cold-weather adhesion is required.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal workers during duct fabrication or repair. Surfaces should be clean, dry, and free of dust or oil before application to ensure proper adhesion. No special applicator tools are required; the tape is hand-tearable for field use. Follow applicable mechanical codes and manufacturer duct-sealing requirements when using tape as part of a duct sealing system.
