It is constructed from 2.0 mil aluminum foil backed with a heavy mastic adhesive that creates a durable, water-resistant bond. The tape measures 3 inches wide and runs 33.33 yards per roll, giving technicians substantial coverage per roll. It carries a UL 723 classification with a 0\/5 Flame\/Smoke rating, making it suitable for applications where code-compliant duct sealing is required. HVAC contractors and sheet metal mechanics are the primary installers of this product.\u003c\/p\u003e\u003cp\u003eThis tape is used in residential and commercial HVAC installations for sealing rigid duct board seams, flexible duct connections, and insulation facing joints. The mastic adhesive provides high deposition coverage, conforming well to irregular surfaces and maintaining adhesion in the temperature ranges typical of forced-air duct systems. The aluminum foil facing reflects heat and resists moisture, making it appropriate for both supply and return-side duct applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.0 mil aluminum foil construction for durability and heat reflectivity\u003c\/li\u003e\n\u003cli\u003eHeavy mastic adhesive provides high deposition and water-resistant bond\u003c\/li\u003e\n\u003cli\u003eUL 723 Classified with 0\/5 Flame\/Smoke rating for code-compliant duct sealing\u003c\/li\u003e\n\u003cli\u003e3 inches wide and 33.33 yards long for efficient coverage per roll\u003c\/li\u003e\n\u003cli\u003eSuitable for duct board seams, insulation splices, and vapor barrier repairs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use foil tape for residential and commercial HVAC duct sealing applications involving rigid duct board, flexible duct, and insulation facing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tape is typically applied by licensed HVAC technicians or sheet metal mechanics during duct fabrication or repair. Power down the air handling system before accessing interior duct surfaces. Ensure all surfaces are clean, dry, and free of dust or oil before applying the tape to achieve full adhesive contact.
