Fiberglass duct construction provides inherent thermal insulation and sound attenuation, reducing both heat loss and system noise at the duct wall. This duct section is installed by HVAC technicians as part of a complete air handling and distribution assembly, typically in residential or light commercial applications where space constraints favor smaller, high-velocity duct runs.\u003c\/p\u003e\u003cp\u003eThis duct section is suited for installations using high-velocity, small-duct HVAC systems where traditional large-diameter ductwork is impractical. It fits within wall cavities, floor joists, and ceiling plenum spaces where compact routing is required. The fiberglass construction makes it appropriate for conditioned-space duct runs where thermal performance and acoustic performance are priorities alongside airflow delivery.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFiberglass construction provides built-in thermal insulation along the duct wall\u003c\/li\u003e\n\u003cli\u003eSound-attenuating material reduces airborne noise transmission through the duct\u003c\/li\u003e\n\u003cli\u003e8.5 inch by 8.5 inch cross-section suits compact, high-velocity duct layouts\u003c\/li\u003e\n\u003cli\u003e4-foot section length allows manageable handling and routing in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style duct section for high-velocity small-duct HVAC distribution systems requiring an 8.5 inch by 8.5 inch rectangular fiberglass duct.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician following local mechanical codes and manufacturer system requirements. Power down and lock out the air handling unit before connecting or modifying any duct section. Secure all joints and seams with approved duct sealant or tape rated for the system operating pressure to prevent air leakage. Handle fiberglass duct sections with appropriate PPE, including gloves and eye protection, to avoid skin and eye irritation from fiberglass particles.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Section Width\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-Section Height\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4 feet (48 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Fiberglass\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: UNICO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: upc-12-085s6-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"UNICO","offers":[{"title":"Default Title","offer_id":51268312695090,"sku":"UPC-12-085S6-4","price":269.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/UPC-12-085S6-4.jpg?v=1780702830","url":"https:\/\/voomisupply.com\/products\/unico-upc-12-085s6-4-fiberglass-duct-8-5x8-5-in-4-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
