Avery Dennison fas-0821-3 Foil Scrim Tape 3in X 50yd

Product Description

The AVERY DENNISON fas-0821-3 is a foil scrim tape supplied in a 3-inch-wide, 50-yard roll. Foil scrim tape combines a reinforced aluminum foil facing with a durable scrim backing, creating a high-strength, vapor-resistant tape used primarily in HVAC duct sealing and insulation work. Its metallic foil construction holds up against heat, moisture, and the mechanical stresses common in air-handling environments. HVAC technicians and insulation contractors reach for this type of tape when sealing flexible duct connections, wrapping rigid board insulation, and closing seams on duct wrap systems.

Foil scrim tape is a standard material in residential and light commercial HVAC installations. It is used to seal and reinforce joints on fiberglass duct board, wrap transitions between duct sections, and provide vapor-barrier continuity at insulation seams. The 3-inch width suits standard duct seam applications without requiring cutting on most installations. It is also used in mechanical rooms and air handler closets where a code-compliant, pressure-sensitive metallic tape is specified.

Key Features

• Aluminum foil facing with scrim reinforcement for added tear resistance
• 3-inch width fits standard duct seam and insulation sealing applications
• 50-yard roll length reduces roll changes on larger jobs
• Pressure-sensitive adhesive bonds to fiberglass duct board, rigid insulation, and metal surfaces
• Vapor-resistant foil construction suitable for HVAC moisture-control applications

Compatibility

Designed as an OEM-style replacement and standard-stock foil scrim tape for use with fiberglass duct board systems, duct wrap insulation, and rigid board insulation in residential and commercial HVAC applications.

Installation Notes

Foil scrim tape is installed by HVAC technicians and insulation contractors working under applicable mechanical and energy codes. Surfaces should be clean, dry, and free of dust or oil before tape application to ensure proper adhesion. No tools beyond a tape dispenser or utility knife are typically required. Follow local energy codes and SMACNA guidelines for duct sealing requirements when specifying this tape for pressure-rated duct systems.
