Measuring 3.5 inches wide by 50 feet long, this white foam roll compresses under the sill plate to create a continuous barrier against drafts, moisture, and the conditions that promote sill plate rot. The material is mildew resistant and water resistant, making it suitable for installation in below-grade and crawl space environments where moisture exposure is a consistent concern. Carpenters, framing contractors, and general contractors typically install this product during rough framing before the sill plate is bolted down.\u003c\/p\u003e\u003cp\u003eThis sill sealer is used in residential and light commercial new construction as well as sill plate replacement projects. It installs between the concrete or masonry foundation wall and the pressure-treated sill plate, filling gaps and surface irregularities that would otherwise allow conditioned air to escape and exterior air to infiltrate. The 50-foot roll length covers a typical residential foundation perimeter with minimal splicing. The white ribbed surface conforms to minor surface variation in the top of the foundation wall.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRibbed polyethylene foam construction conforms to uneven foundation wall surfaces\u003c\/li\u003e\n\u003cli\u003eReduces air leakage at the sill plate-to-foundation interface\u003c\/li\u003e\n\u003cli\u003eMildew resistant and water resistant for use in high-moisture environments\u003c\/li\u003e\n\u003cli\u003eProvides protection against conditions that contribute to sill plate rot\u003c\/li\u003e\n\u003cli\u003e3.5-inch width fits standard dimensional lumber sill plates\u003c\/li\u003e\n\u003cli\u003e50-foot roll minimizes seams on typical residential foundations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and new-construction sill sealer for use with standard dimensional lumber sill plates installed over concrete or masonry foundation walls.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by framing carpenters or general contractors during the foundation sill plate stage of construction. Unroll the foam sealer along the top of the foundation wall and position it before setting and fastening the sill plate. No adhesive is required under normal conditions, as the sill plate weight and anchor bolt hardware compress and hold the sealer in place. Follow local building codes for sill plate anchoring requirements and consult the applicable building code for air barrier continuity requirements at the foundation-to-wall transition.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Ribbed Polyethylene Foam\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm Factor\u003c\/strong\u003e: Roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 36 per case\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: REFLECTIX INC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CF30550\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"REFLECTIX","offers":[{"title":"Default Title","offer_id":51524687364402,"sku":"CF30550","price":235.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/731932f781147cac4cf143bad7d50194.jpg?v=1785455266","url":"https:\/\/voomisupply.com\/products\/reflectix-inc-cf30550-foam-sill-sealer-3-5x50-ft-white","provider":"Voomi Supply","version":"1.0","type":"link"}
