The unit features a weather-tight seamed collar that seals against moisture intrusion at the deck penetration. A large nailing flange simplifies attachment to the roof deck and helps create a secure, low-profile installation. The three-sided louver design increases the effective air intake area compared to standard two-sided louvers, improving passive airflow through the attic cavity. Overall dimensions measure 16 inches by 20.3125 inches by 5 inches, with an 8-inch opening size. The brown aluminum finish reduces the risk of roof discoloration around the vent over time.\u003c\/p\u003e\n\u003cp\u003eThis louver is suited for sloped residential roofs where continuous ridge ventilation is not used or where supplemental point ventilation is needed. It is commonly installed in attic spaces to exhaust trapped heat and moisture buildup, which can degrade roof deck sheathing and insulation. Roofers and general contractors typically install this unit during new construction or re-roofing projects. The slant-back profile sheds water away from the opening and maintains a low visual footprint on the roof surface.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-inch opening size suits standard roof deck cutouts for residential attic exhaust\u003c\/li\u003e\n  \u003cli\u003eThree-sided louver configuration increases airflow compared to two-sided designs\u003c\/li\u003e\n  \u003cli\u003eWeather-tight seamed collar resists moisture intrusion at the deck penetration\u003c\/li\u003e\n  \u003cli\u003eLarge nailing flange provides secure attachment and simplifies installation\u003c\/li\u003e\n  \u003cli\u003eBrown aluminum finish helps prevent roof discoloration around the vent\u003c\/li\u003e\n  \u003cli\u003eSlant-back design sheds water and maintains a low profile on the roof surface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install roof louver for residential sloped-roof attic ventilation systems requiring an 8-inch opening.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed roofer or general contractor. Power any associated attic ventilation equipment off before beginning work, and follow local building code requirements for attic ventilation net free area as outlined in the IRC. Apply roofing sealant or flashing per the manufacturer and local code requirements around the nailing flange to prevent water infiltration. Do not install on roof pitches or in locations outside the product's rated application range without verifying adequacy for the specific installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOpening Size\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Dimensions\u003c\/strong\u003e: 16 inches x 20.3125 inches x 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\/Finish\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProfile Style\u003c\/strong\u003e: Slant Back\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LOMANCO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 750BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOMANCO","offers":[{"title":"Default Title","offer_id":51525285052722,"sku":"750BR","price":207.37,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50d2d9dd7120bc83833e7279cf8ebdb2_f38017fa-85b5-444a-8c71-a05dc0eef5f8.jpg?v=1785469551","url":"https:\/\/voomisupply.com\/products\/lomanco-750br-aluminum-roof-louver-8-inches-brown","provider":"Voomi Supply","version":"1.0","type":"link"}
