2" x 50 Yds. Aluminum Foil Tape

Shurtape AF 914CT Cold Temperature Foil Tape – Acrylic Adhesive, UL 181A-P Listed

The Shurtape AF 914CT is a 1.5 mil dead-soft aluminum foil tape engineered for cold weather HVAC system sealing, particularly in environments requiring performance below freezing. It utilizes a cold-temperature rated acrylic adhesive and meets UL 181A-P standards for use in rigid fiberglass duct board systems.

This foil tape is formulated for permanent, pressure-sensitive bonding and delivers high shear strength and excellent resistance to moisture, UV, and aging. It is suitable for use on foil-faced insulation, rigid ducts, and air handling applications that require a secure, vapor-tight closure across a broad temperature spectrum.
