It features a dead-soft aluminum foil backing paired with a pressure-sensitive acrylic adhesive engineered for long-term durability. The tape measures 4 inches wide on a 54.86-meter roll. It is rated by UL to UL 746C and classified by UL to UL 723, Class L for low flammability. HVAC technicians, sheet metal workers, and industrial maintenance professionals are the primary installers of this product.\u003c\/p\u003e\u003cp\u003eThis foil tape is suited for residential and commercial HVAC duct seaming and sealing, heat shielding in high-temperature environments, and surface protection applications requiring reflectivity or moisture resistance. It performs in demanding conditions involving flame exposure, weathering, UV, and moisture. The acrylic adhesive bonds firmly during service but removes cleanly after masking use, making it practical for temporary and permanent applications alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDead-soft aluminum foil backing for effective heat shielding in demanding applications\u003c\/li\u003e\n\u003cli\u003ePressure-sensitive acrylic adhesive provides long-term durability and clean removal after masking\u003c\/li\u003e\n\u003cli\u003eWithstands exposure to flame, weathering, moisture, and UV\u003c\/li\u003e\n\u003cli\u003eHeat and light reflective surface protects substrates and can enhance lighting efficiency\u003c\/li\u003e\n\u003cli\u003eUL Recognized to UL 746C and UL Classified to UL 723, Class L low flammability rating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in HVAC duct seaming and sealing, heat shielding, and surface protection applications across residential, commercial, and industrial settings.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by HVAC technicians or sheet metal workers.
