Avery Dennison 955m2 Metalized Cloth Duct Tape 48mm X 55m

Product Description

The AVERY DENNISON 955m2 is a 12-mil metalized cloth duct tape from the Fasson 955 Series, designed for HVAC duct sealing and related mechanical insulation applications. The aluminum-metalized backing provides a durable, reflective surface that holds up under thermal cycling. With a maximum performance temperature of 200 degrees F, this tape is suited for high-heat areas including supply and return duct assemblies, duct board seams, and flexible duct connections. It is classified under UL 723, confirming it meets flame spread and smoke developed requirements for use in air-handling applications. HVAC technicians and sheet metal contractors are the primary installers of this product.

This tape is used in residential and light commercial HVAC duct systems where a UL 723 listed tape is required by code or specification. It is well suited for sealing foil-faced duct board, rigid fiberglass ductwork, and sheet metal duct seams. The 48mm width and 55-meter roll length make it a practical choice for field work where coverage per roll matters. It performs in both supply-side and return-side duct applications and is commonly applied in attic, crawlspace, and mechanical room environments.

Key Features

• 12-mil total thickness for added conformability and tear resistance during application
• Metalized cloth backing provides a reflective, aluminum-faced surface compatible with foil duct systems
• Maximum performance temperature of 200 degrees F for high-heat duct environments
• UL 723 classified for flame spread and smoke developed compliance in air-handling assemblies
• 48mm x 55m roll format sized for field use and extended coverage

Compatibility

Designed as an OEM-style replacement and general-use tape for residential and commercial HVAC duct sealing applications requiring a UL 723 classified metalized cloth product.

Installation Notes

This tape is applied by HVAC technicians and sheet metal workers as part of duct sealing and insulation work. Surfaces should be clean, dry, and free of dust or oils before application to ensure full adhesive contact. Most jurisdictions require UL 723 listed tapes when sealing ducts in air-handling plenums — verify local mechanical code requirements before installing. Do not apply to surfaces exceeding the rated maximum temperature of 200 degrees F.
