Nashua 324A_3X60YD Aluminum Foil Tape 3 in X 60 Yd Ul 181

Product Description

The NASHUA 324A_3X60YD is a premium cold weather aluminum foil tape engineered for HVAC duct sealing, insulation repair, and dryer vent applications. The tape measures 3 inches wide by 60 yards long with a 4.8 mil total thickness. Construction consists of an aluminum foil backing, an aggressive acrylic adhesive formulated for low-temperature performance, and a kraft paper release liner. The acrylic adhesive maintains bond strength in conditions as cold as -25 degrees F and holds up to 325 degrees F, making it suitable for year-round installation in unconditioned spaces. HVAC technicians and sheet metal mechanics are the primary installers for this product.

This tape is used on Class 1 flexible duct connections and seams, rigid duct insulation seams and patches, and dryer vent seals. It meets UL 181A-P and UL 181B-FX printed tape requirements, making it code-acceptable for duct sealing on listed flexible and rigid duct systems. The single-coated aluminum construction resists mold and mildew growth and performs consistently across a wide range of climate conditions. Projects pursuing LEED certification may use this tape to contribute toward EA Credit 1 (Optimize Energy Performance) and EQ Credit 4.1 (Low Emitting Materials) due to its low VOC content.

Key Features

• Aggressive cold weather acrylic adhesive rated from -25 to 325 degrees F
• Meets UL 181A-P and UL 181B-FX printed tape standards for listed duct systems
• Low VOC content supports LEED EQ Credit 4.1 (Low Emitting Materials)
• Resists mold and mildew growth in humid or unconditioned environments
• Aluminum foil backing with kraft paper liner for clean, controlled unwind
• Single-coated construction for direct application to duct and insulation surfaces

Compatibility

Rated for use on Class 1 flexible duct sealing, insulation seam and patch applications, and dryer vent seals. Meets UL 181A-P and UL 181B-FX requirements for use with UL-listed flexible and rigid duct systems where a printed foil tape is specified by code.

Installation Notes

Installation is typically performed by licensed HVAC technicians or sheet metal mechanics in accordance with local mechanical codes and SMACNA duct construction standards. Shut down the air handling system and confirm the duct surface is clean, dry, and free of dust or oil before applying tape. Firm hand pressure or a seam roller should be used across the full tape width to ensure full adhesive contact. Do not apply over wet insulation or surfaces below the adhesive rated minimum temperature without confirming bond integrity.
