This tape combines a metallic foil facing with a mastic adhesive backing to create a durable, conformable seal on irregular or rough surfaces. It is typically installed by roofing contractors, waterproofing specialists, and HVAC technicians where a weather-resistant, vapor-retarding bond is required. The 3-inch width suits standard seam and penetration sealing tasks encountered on commercial and residential jobsites.\u003c\/p\u003e\u003cp\u003eFoil mastic tape of this type is commonly used to seal seams on ductwork, roof flashings, vapor barriers, and waterproofing membranes. It performs well in applications where a standard pressure-sensitive tape would not conform adequately to surface irregularities. The mastic adhesive layer bridges gaps and adheres to metal, concrete, masonry, and insulation board substrates, making it a versatile choice across roofing, below-grade waterproofing, and mechanical insulation scopes of work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch width suits standard seam sealing and penetration flashing tasks\u003c\/li\u003e\n\u003cli\u003eFoil facing provides weather resistance and vapor retardancy\u003c\/li\u003e\n\u003cli\u003eMastic adhesive conforms to irregular and rough substrate surfaces\u003c\/li\u003e\n\u003cli\u003eSuitable for use on metal, masonry, concrete, and insulation board\u003c\/li\u003e\n\u003cli\u003eApplicable across roofing, waterproofing, and HVAC duct sealing scopes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-use foil mastic tape suitable for duct sealing, roofing membrane seam work, and waterproofing applications where a conformable foil-backed mastic product is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFoil mastic tape should be installed by qualified roofing, waterproofing, or HVAC personnel following applicable local building codes and manufacturer surface preparation requirements. Substrates must be clean, dry, and free of dust, oil, and loose material before tape application to ensure proper adhesion. Press the tape firmly into place, working out air bubbles from the center toward the edges. Do not apply to wet or frozen surfaces, as adhesion will be compromised.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFacing Material\u003c\/strong\u003e: Foil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdhesive Type\u003c\/strong\u003e: Mastic\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CARLISLE COATINGS WATERPROOFING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 325804\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARLISLE COATINGS \u0026 WATERPROOFING","offers":[{"title":"Default Title","offer_id":51306543186226,"sku":"325804","price":65.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549442.webp?v=1781291318","url":"https:\/\/voomisupply.com\/products\/carlisle-coatings-waterproofing-325804-foil-mastic-tape-3in","provider":"Voomi Supply","version":"1.0","type":"link"}
