The roll measures 1.25 inches thick, 4 feet wide, and 64 feet long, providing 256 square feet of coverage per roll. Its flexible EPS core delivers an R-value of 5.3 at 25 degrees F and 4.5 at 75 degrees F, reducing heat loss downward through the slab so radiant energy transfers efficiently into the living space above. Vapor-retarding films are bonded to both sides of the core. A patented self-taping edge and overlapping flange allow seam-free installation without additional tape or separate vapor barrier materials. Licensed plumbers and radiant heating contractors are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe EBAR-464X5 is intended for underslab applications in residential and light commercial radiant floor heating projects. It is placed directly on the subgrade or aggregate base before concrete is poured. The combination of thermal insulation and integrated vapor retarder makes it suited for slab-on-grade construction where both heat retention and moisture control are required. The roll format and flexible EPS core allow it to conform to layout changes and irregular floor plans without cracking or breaking during handling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eR-value of 5.3 at 25 degrees F and 4.5 at 75 degrees F for effective downward heat loss reduction\u003c\/li\u003e\n  \u003cli\u003eFlexible, recyclable EPS core resists cracking during handling and installation\u003c\/li\u003e\n  \u003cli\u003eVapor-retarding films bonded to both sides eliminate the need for a separate vapor barrier\u003c\/li\u003e\n  \u003cli\u003ePatented self-taping edge and overlapping flange create seam-free coverage across the entire floor area\u003c\/li\u003e\n  \u003cli\u003e256 square feet of coverage per roll reduces material handling and lap count\u003c\/li\u003e\n  \u003cli\u003eRated for continuous use up to 180 degrees F, compatible with typical radiant heating system operating temperatures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an underslab insulation and vapor retarder for radiant floor heating systems installed beneath poured concrete slabs in residential and light commercial construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers or radiant heating contractors as part of the rough-in phase before concrete placement. Power down and pressure-test any embedded radiant tubing per the system manufacturer's instructions before the slab is poured. Ensure the subgrade is properly compacted and free of sharp objects that could puncture the film facing. Follow applicable building codes and the project engineer's specifications for vapor retarder overlap and perimeter detailing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 64 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoverage\u003c\/strong\u003e: 256 square feet per roll\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eR-Value\u003c\/strong\u003e: 5.3 at 25 degrees F \/ 4.5 at 75 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 180 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Expanded Polystyrene (EPS) with bonded vapor-retarding film facing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Radiant Heat Underslab\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: NORTHWESTERN OHIO FOAM PRODUCTS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EBAR-464X5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTHWESTERN OHIO FOAM PRODUCTS","offers":[{"title":"Default Title","offer_id":51345088381234,"sku":"EBAR-464X5","price":375.98,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554773.jpg?v=1782049393","url":"https:\/\/voomisupply.com\/products\/northwestern-ohio-foam-products-ebar-464x5-underslab-insulation-roll","provider":"Voomi Supply","version":"1.0","type":"link"}
