The 1.8 mil aluminum foil backing is coated with a cold-weather acrylic pressure-sensitive adhesive that maintains bond strength in low-temperature environments. The tape measures 2.83 inches wide and 50 yards long per roll, providing substantial coverage for field applications. It is hand-tearable, eliminating the need for a dispenser or cutting tool on the job. The UL 723 classification with a 5\/10 flame and smoke rating and ULC S102 classification with a 10\/0 rating make it suitable for installations where fire and smoke performance requirements apply.\u003c\/p\u003e\n\u003cp\u003eThis tape is used primarily in residential and light commercial HVAC installations for sealing rigid and flexible duct joints, securing duct insulation, and repairing foil-faced insulation. It performs in cold-weather conditions, making it appropriate for work in unconditioned spaces such as attics, crawlspaces, and mechanical rooms during winter months. HVAC technicians and sheet metal workers are the primary installers. The cold-weather adhesive activates with hand pressure and does not require heat for activation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.8 mil dead-soft aluminum foil backing conforms to irregular duct surfaces\u003c\/li\u003e\n  \u003cli\u003eCold-weather acrylic pressure-sensitive adhesive maintains bond in low-temperature conditions\u003c\/li\u003e\n  \u003cli\u003eHand-tearable — no dispenser or cutting tool required\u003c\/li\u003e\n  \u003cli\u003eUL 723 Classified with 5\/10 Flame\/Smoke Rating\u003c\/li\u003e\n  \u003cli\u003eULC S102 Classified with 10\/0 Flame\/Smoke Rating\u003c\/li\u003e\n  \u003cli\u003e2.83 inches wide by 50 yards per roll for extended coverage\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with rigid fiberglass duct board, sheet metal ductwork, and foil-faced insulation in residential and commercial HVAC systems where UL 723 or ULC S102 flame and smoke performance is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians or sheet metal workers in accordance with SMACNA guidelines and local mechanical codes.
