Bsc Preferred T963425 Aluminum Foil Hvac Tape 48 Pack

Product Description

The BSC PREFERRED T963425 is a premium-grade aluminum-backed foil tape designed for HVAC ductwork sealing, insulation facing repairs, and thermal barrier applications. The tape features an acrylic adhesive backing that bonds to sheet metal, rigid foam, and flexible duct surfaces. It is thermally conductive, supporting both heating and cooling system efficiency, while providing a waterproofing barrier and air leak protection. The tape is flame resistant, heat reflective, and light reflective, meeting UL 723, Class L File R 7311 and UL 764c requirements. Resistance to ultraviolet degradation supports long-term outdoor and attic-environment performance.

This tape is suited for residential and commercial HVAC installations where code-compliant duct sealing is required. It is commonly used to seal duct joints, seams, and insulation seams on supply and return air systems. The reflective aluminum surface improves visibility in low-light crawlspace and attic environments by magnifying available light sources. This product is sold as a case of 48 rolls and is equivalent to part number S-10308. Licensed HVAC technicians and sheet metal contractors are the primary installers.

Installation Notes

Installation is performed by licensed HVAC technicians or sheet metal contractors. Power down the air handling system and allow duct surfaces to cool before applying tape. Surfaces must be clean, dry, and free of dust or grease for proper acrylic adhesive bonding. Consult applicable mechanical codes, including SMACNA standards, for duct sealing requirements in your jurisdiction.
