The tape measures 3\/8 inch wide by 1\/2 inch thick and comes in a 10-foot roll. Its grey closed-cell PVC foam construction resists water absorption and compresses to form a durable airtight seal. The pressure-sensitive adhesive backing allows for tool-free application on clean, dry surfaces. HVAC technicians, plumbers, and general contractors reach for this tape when sealing gaps that compromise thermal or moisture performance.\u003c\/p\u003e\u003cp\u003eThe V445H is suited for residential and light commercial applications where air sealing and weatherproofing are required. Common install scenarios include sealing around door frames, window stops, attic access hatches, pipe penetrations, and equipment access panels. The closed-cell foam holds its shape under compression, making it effective in locations where the gap width is consistent. The grey color blends with painted metal and standard door frame finishes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eClosed-cell PVC foam resists water absorption and maintains an airtight seal\u003c\/li\u003e\n\u003cli\u003eSelf-sticking pressure-sensitive adhesive — no additional fasteners or adhesives required\u003c\/li\u003e\n\u003cli\u003e3\/8 inch wide by 1\/2 inch thick profile fits standard weatherstripping gaps\u003c\/li\u003e\n\u003cli\u003e10-foot roll length suits single-door or window perimeter applications\u003c\/li\u003e\n\u003cli\u003eGrey finish suitable for metal frames, painted wood, and equipment panels\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose weatherstrip replacement tape compatible with standard residential and light commercial door and window frames where closed-cell foam tape with a 3\/8 inch by 1\/2 inch cross-section is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface preparation is critical — clean the substrate with a dry cloth or isopropyl alcohol and allow it to dry fully before applying the tape. Power down or shut off any HVAC equipment before sealing around air handler access panels or duct penetrations. Press the foam firmly along the full length of the seal to ensure full adhesive contact. Follow local building codes and manufacturer guidelines for air-sealing applications in conditioned spaces.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Closed-Cell Polyvinyl Chloride Foam\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 10 feet per roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Grey\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdhesive Type\u003c\/strong\u003e: Pressure-Sensitive Self-Stick\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 24 rolls per case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Weight\u003c\/strong\u003e: 6 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: THERMWELL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: V445H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FROST KING","offers":[{"title":"Default Title","offer_id":51559494418738,"sku":"V445H","price":55.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e77ffe69b22d33e54546cef45cb7b40.jpg?v=1786433796","url":"https:\/\/voomisupply.com\/products\/thermwell-v445h-foam-weatherstrip-tape-3-8x1-2-in-grey","provider":"Voomi Supply","version":"1.0","type":"link"}
