3M 7000122328 Aluminum Foil Tape 1 in X 60 Yd Acrylic

Product Description

The 3M 7000122328 is a general-purpose aluminum foil tape designed for HVAC duct sealing, insulation facing repairs, and thermal protection applications. It is coated with an aggressive acrylic adhesive that delivers reliable adhesion across a wide temperature range, making it suitable for both high-heat and cold environments. The malleable aluminum foil backing conforms to irregular surfaces and contours without cracking or lifting. This tape resists flame, moisture, UV exposure, and chemical contact, supporting long-term durability in demanding mechanical and building environments. Licensed HVAC technicians and sheet metal workers are the primary installers of this product.

This tape is used in residential and light commercial HVAC installations, primarily for sealing and joining flexible and rigid duct assemblies, patching insulation vapor barriers, and wrapping heat-sensitive components. Its high heat reflectivity and thermal conductivity help maintain system efficiency by minimizing heat transfer losses at seams and joints. The foil can be torn by hand, which speeds up field installation without requiring a dispenser or cutting tool.

Key Features

• Aggressive acrylic adhesive performs across a wide temperature range including high and low extremes
• Aluminum foil backing offers high heat reflectivity and thermal conductivity for improved heating and cooling efficiency
• Resistant to flame, moisture, UV radiation, and chemical exposure for long-term durability
• Malleable foil conforms to irregular shapes, curves, and uneven surfaces
• Can be torn by hand for fast, tool-free application in the field
• Protects heat-sensitive components through light and heat reflectivity

Compatibility

Designed as a general-purpose aluminum foil tape suitable for HVAC duct sealing, insulation repairs, and thermal shielding applications on a wide variety of substrate surfaces.

Installation Notes

This tape is typically applied by licensed HVAC technicians and sheet metal workers during duct fabrication or repair. Surfaces should be clean, dry, and free of dust or oil before application to ensure full adhesive contact. When used on duct systems, verify that the tape meets local mechanical code requirements for duct sealing materials. No power disconnection is required for tape-only applications, but follow standard lockout procedures if working on energized air handling equipment.
