Built from natural and recycled stone wool fibers, it delivers both superior acoustic dampening and non-combustible fire resistance in a single product. The material is dimensionally stable, making friction-fit installation into standard wood and steel stud framing straightforward without adhesives or mechanical fasteners. It is chemically inert and will not promote corrosion, rot, fungi, or mildew growth. Low moisture absorption and resistance to water make it suitable for areas prone to humidity. This batt is typically installed by framing contractors, insulation crews, or licensed general contractors during new construction or retrofit projects.\u003c\/p\u003e\u003cp\u003eThe RXSS31525 is intended for interior wall partitions in residential wood-stud and steel-stud construction where both acoustical control and fire resistance are primary design requirements. Common applications include party walls, bedroom walls, home theater rooms, and floor-ceiling assemblies where sound transmission must be minimized. Its high-temperature melting point of approximately 2150 degrees F (1177 degrees C) gives it a strong passive fire-resistance profile compared to fiber glass alternatives. The product is CFC-free and HCFC-free, and its material composition can contribute to LEED project points.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNon-combustible stone wool with a melting point of approximately 2150 degrees F, providing passive fire resistance\u003c\/li\u003e\n\u003cli\u003eExcellent acoustic dampening properties for use in sound-sensitive interior partitions and floor-ceiling assemblies\u003c\/li\u003e\n\u003cli\u003eDimensionally stable for reliable friction fit into standard wood and steel stud cavities without fasteners\u003c\/li\u003e\n\u003cli\u003eChemically inert and non-corrosive; will not promote rot, mildew, fungi, or metal corrosion\u003c\/li\u003e\n\u003cli\u003eLow moisture absorption and water-resistant for long-term performance in humid environments\u003c\/li\u003e\n\u003cli\u003eCFC-free and HCFC-free; made from natural and recycled materials with LEED contribution potential\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for friction-fit installation in residential interior wall partitions, floor assemblies, and ceiling cavities using standard wood or steel stud framing systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by insulation contractors or framing crews following local building code requirements. Always wear appropriate personal protective equipment including gloves, eye protection, and a dust mask when cutting or handling stone wool batts. Power down any electrical circuits in the work area before insulating around wiring. Cut batts with a utility knife and straightedge to achieve clean, snug fits around obstructions without compressing the material, as compression reduces acoustical performance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stone wool (natural and recycled)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Interior wall partitions, floor-ceiling assemblies, residential wood and steel stud framing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFire Resistance\u003c\/strong\u003e: Non-combustible; melting point approximately 2150 degrees F (1177 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical Properties\u003c\/strong\u003e: Chemically inert, non-corrosive, CFC-free, HCFC-free\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMoisture Resistance\u003c\/strong\u003e: Low moisture absorption, water and moisture resistant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 37.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Bag\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ROCKWOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RXSS31525\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROCKWOOL","offers":[{"title":"Default Title","offer_id":51717989925170,"sku":"RXSS31525","price":124.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5de15ccb0e737a48b36e0d2e41dac70f.jpg?v=1788548128","url":"https:\/\/voomisupply.com\/products\/rockwool-rxss31525-stone-wool-acoustic-insulation-batts","provider":"Voomi Supply","version":"1.0","type":"link"}
