Nashua 322_2X50YD Aluminum Foil Tape 2in X 50yd 5 Mil

Product Description

The NASHUA 322_2X50YD is a plain foil tape designed for sealing joints and seams on foil-jacketed insulation in HVAC, mechanical, and construction applications. The tape measures 2 inches wide by 50 yards long and carries a 5 mil total thickness. Its construction combines an aluminum foil backing with a synthetic rubber adhesive and an unbleached natural kraft paper liner. The aggressive high-tack adhesive delivers a conformable bond across corners, irregular joints, and flat seams, and the aluminum backing provides UV resistance, moisture resistance, and mold and mildew resistance throughout the service life of the installation.

This tape is widely used by HVAC technicians and insulation contractors for seaming foil jacketing on ductwork and mechanical insulation. It also sees use in general construction repair and automotive industry applications where a conformable, weather-resistant aluminum tape is required. The low VOC, non-solvent adhesive system makes it suitable for enclosed or occupied spaces. The tape is rated for service temperatures from 40 degrees F to 200 degrees F, supporting both cold-side and warm-side insulation applications. It meets flammability requirements for construction and marine use and can contribute toward satisfying EQ Credit 4.1 under LEED certification programs.

Key Features

• Synthetic rubber adhesive with extreme high tack for aggressive bonding to foil, film, and insulation surfaces
• Conformable construction wraps corners and irregular joints without lifting or bridging
• UV resistant, moisture resistant, and mold and mildew resistant aluminum foil backing
• Low VOC, non-solvent adhesive reduces odor and supports LEED EQ Credit 4.1 compliance
• Rated for temperatures from 40 degrees F to 200 degrees F
• Meets UL 723 and PSTC 101 standards; suitable for construction and marine flammability requirements

Compatibility

Designed for taping joints and seams against moisture and vapor on foil jacketing insulation; also suitable for general construction repair and automotive industry applications where an aluminum foil tape meeting UL 723 and LEED requirements is specified.

Installation Notes

Installation is typically performed by HVAC technicians or insulation contractors as part of duct insulation or mechanical pipe insulation work. Clean and dry all surfaces before applying the tape to ensure full adhesive contact. Remove the kraft paper liner fully before application and press the tape firmly from the center outward to eliminate air pockets along seams and corners. Where local codes reference insulation sealing requirements, consult SMACNA or applicable mechanical code standards for minimum tape coverage and overlap specifications.
