This 1-1\/2 inch thick sheet functions as the system's primary brain for temperature retention, engineered with a tough, flame-retardant foil-scrim-kraft (FSK) vapor barrier. Specifically designed for the fabrication of rectangular ductwork, the T0800 ensures that conditioned air reaches its destination without the thermal energy loss or \"sweating\" common in uninsulated metal ducts. By absorbing mechanical vibrations and airflow turbulence, this duct board provides whisper-quiet operation while maintaining superior indoor air quality through its antimicrobial-treated interior surface. \u003c\/p\u003e\n\u003cp\u003eKey Features\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine Owens Corning Part Number T0800:\u003c\/strong\u003e Guaranteed professional-grade fit featuring a high-density fiberglass core for maximum structural integrity in custom duct fabrication.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior 1-1\/2\" Thermal Insulation:\u003c\/strong\u003e Specifically engineered to provide an R-6.0 or higher thermal value, preventing condensation and significantly lowering energy consumption.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEliminate Noise and Vibration Issues:\u003c\/strong\u003e Replaces loud, echoing sheet metal ducts with sound-absorbing fiberglass that traps \"fan roar\" and prevents the popping sounds of thermal expansion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Safety Monitoring:\u003c\/strong\u003e Manufactured with a UL 181 Class 1 rating, ensuring the board meets the strictest fire safety and smoke-developed standards for residential and commercial use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAntimicrobial Interior Surface:\u003c\/strong\u003e Features a specialized coating that prevents the growth of mold and bacteria, protecting your home’s air supply from biological contaminants. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProduct Details\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Owens Corning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Owens Corning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e OC80011\/2SHEETQ (T0800)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 1-1\/2\" Thick x 48\" Wide x 120\" Long (10 Feet)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Resistance:\u003c\/strong\u003e R-6.3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVapor Barrier:\u003c\/strong\u003e Foil-Scrim-Kraft (FSK) Facings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFire Rating:\u003c\/strong\u003e UL 181 Class 1 Air Duct\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Velocity:\u003c\/strong\u003e 5,000 FPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature:\u003c\/strong\u003e 250°F (Internal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 18.5 lbs per sheet \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e🛠️ HVAC Depot Pro Tip\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTake a Picture First —\u003c\/strong\u003e Before you begin grooving or folding the sheet, photograph the printed UL 181 label and the R-value specifications on the FSK facing. This visual record is often required by local building inspectors to verify code compliance after the duct is installed and sealed. When fabricating, ensure you use a dedicated duct board knife set to achieve clean 90-degree V-grooves; jagged cuts will lead to air leakage and structural weakness. Always seal all exterior seams with UL 181A-P pressure-sensitive tape or UL 181A-M mastic to guarantee a 100% airtight seal. \u003c\/p\u003e\n\u003cp\u003eCross-Reference\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperseded Parts:\u003c\/strong\u003e OC-T800-1.5, 800-112-FSK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLegacy Drawing Numbers:\u003c\/strong\u003e Type 800, Type 1000 (Heavy Duty), UL 181 Class 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquivalent Brands:\u003c\/strong\u003e Johns Manville Super-V, Knauf Air duct Board, CertainTeed Ultra*Duct \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eModel Compatibility\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eResidential Supply Plenums\u003c\/strong\u003e (Suffixes: High-Efficiency Gas and Electric Systems)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReturn Air Trunk Lines\u003c\/strong\u003e (Suffixes: Central Air and Heat Pump Series)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommercial Branch Ducts\u003c\/strong\u003e (Suffixes: VAV and Constant Volume Systems)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom Transition Boxes\u003c\/strong\u003e (Suffixes: Furnace to Coil Adaptors)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Owens Corning","offers":[{"title":"Default Title","offer_id":52451496591723,"sku":"038330080017","price":120.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/original_5d1f8a6e-7853-4b77-9c59-c5f32409f6d9.png?v=1760124153","url":"https:\/\/tophvacparts.com\/products\/owens-corning-t0800-duct-board-sheet-1-1-2-x-48-x-120-high-performance-rigid-fiberglass-insulation","provider":"HVAC Parts and Equipment Depot Open To Homeowners and Contractors","version":"1.0","type":"link"}
