3M 7100087495 White Foil Tape 4.87in X 50yd Asj Insulation

Product Description

The 3M 7100087495 is a white kraft paper, scrim, and foil laminated tape designed for vapor sealing on ductboard and pipe insulation. It uses a pressure-sensitive, cold-weather solvent acrylic adhesive that delivers quick stick at normal temperatures and maintains bond strength in low-temperature and high-humidity conditions. A built-in mold inhibitor helps preserve adhesive effectiveness over time. The roll measures 4.87 inches wide and 50 yards long, making it well suited for full-run duct wrap and insulation sealing tasks in mechanical and HVAC applications. Licensed HVAC technicians and insulation installers are the primary users of this tape.

This tape is commonly applied as an ASJ (All Service Jacket) facing tape on ductboard and rigid or flexible pipe insulation. It is well suited for residential and light commercial HVAC installations where low ambient temperatures during application are a concern, such as unconditioned attic spaces, crawlspaces, and mechanical rooms. The flexible backing conforms to curved pipe surfaces and irregular duct geometries without lifting or flagging at the edges.

Key Features

• White kraft, scrim, and foil laminate backing provides an effective vapor seal on ductboard and pipe insulation
• Cold-weather acrylic adhesive maintains bond at low temperatures where standard tapes fail
• Mold inhibitor helps preserve adhesive strength in humid environments
• High puncture and tear resistance for long service life in demanding mechanical spaces
• Flexible backing conforms to curved and irregular surfaces without delaminating
• No special tools or application equipment required for field installation

Compatibility

Designed as an ASJ facing tape for use on ductboard and pipe insulation systems in residential and commercial HVAC applications.

Installation Notes

Installation is typically performed by licensed HVAC technicians or insulation contractors. Clean and dry all surfaces before application to ensure full adhesive contact. Apply firm hand pressure along the full tape length to activate the pressure-sensitive adhesive. Follow applicable mechanical codes and insulation manufacturer guidelines for vapor barrier continuity and overlap requirements.
