It features a tri-directionally reinforced film, scrim, and kraft (FSK) construction paired with a cold-weather acrylic pressure-sensitive adhesive. The tape delivers extremely low vapor permeability at 0.02 perms, making it well-suited for vapor retarder applications where moisture control is critical. Each roll measures 2.83 inches wide by 50 yards long. HVAC technicians and mechanical insulation contractors install this product to seal joints, seams, and laps on duct and pipe insulation systems.\u003c\/p\u003e\u003cp\u003eThis tape is used in commercial and residential mechanical insulation work, primarily for sealing FSK-faced duct wrap, duct board, and pipe insulation. It is appropriate for new construction and retrofit applications where vapor retarder integrity is required. The cold-weather acrylic adhesive maintains bond strength in low-temperature installation environments, which is common during winter mechanical work. Installers applying this tape to rigid duct board, flexible duct wrap, or pipe insulation in unconditioned spaces will find it well-matched to those conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTri-directional scrim reinforcement resists tearing during application and in service\u003c\/li\u003e\n\u003cli\u003eCold-weather acrylic pressure-sensitive adhesive bonds in low-temperature conditions\u003c\/li\u003e\n\u003cli\u003e0.02 perm rating meets vapor retarder requirements in insulation assemblies\u003c\/li\u003e\n\u003cli\u003eMeets ASTM C1136 Type II and Type IV classifications\u003c\/li\u003e\n\u003cli\u003eWhite metalized polypropylene facing suits exposed insulation aesthetics\u003c\/li\u003e\n\u003cli\u003e2.83-inch width covers standard insulation seams and laps in a single pass\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitment tape for FSK-faced duct wrap, duct board, and pipe insulation systems requiring ASTM C1136 Type II and Type IV compliant vapor retarder facing tape.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tape is typically installed by licensed HVAC technicians or mechanical insulation contractors following SMACNA and manufacturer insulation system guidelines. Surfaces must be clean, dry, and free of dust or oil before application for full adhesive contact. Press the tape firmly across the full seam width to eliminate air pockets and ensure vapor retarder continuity. No cutting tools beyond a standard tape dispenser or utility knife are required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.83 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 yards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdhesive Type\u003c\/strong\u003e: Cold-weather acrylic pressure-sensitive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFacing Material\u003c\/strong\u003e: White metalized polypropylene film with scrim and kraft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVapor Permeability\u003c\/strong\u003e: 0.02 perms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eASTM Classification\u003c\/strong\u003e: C1136 Type II and Type IV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 23.202 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100043931\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346920374578,"sku":"7100043931","price":695.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530855.jpg?v=1782094615","url":"https:\/\/voomisupply.com\/products\/3m-7100043931-foil-tape-white-2-83-in-x-50-yd","provider":"Voomi Supply","version":"1.0","type":"link"}
