Non-combustible and water-repellent, it ensures safety, energy savings, and long-term durability for demanding residential and commercial projects. ## Description The Ultimate High-Performance Insulation for Sound, Fire, and Thermal Control. When your project demands the highest level of performance, Rockwool 8# Density Foil-Faced Stone Wool Insulation is a professional-grade product engineered to provide a robust, all-in-one solution for the most demanding acoustic, thermal, and fire-safety applications. Superior Performance by Design The high-density 8 lb/ft³ core provides exceptional mass for blocking sound transmission between rooms, making it the go-to material for soundproofing home theaters, studios, offices, and commercial spaces. The durable, reinforced foil (FSK) facing enhances this performance by acting as a built-in vapor barrier to protect your wall assemblies from moisture, while also serving as a radiant barrier to improve energy efficiency. Uncompromising Safety and Durability Made from natural stone, Rockwool is non-combustible and provides a critical layer of fire resistance, helping to slow the spread of fire and providing valuable time in an emergency. The rigid and durable composition of these panels ensures they are easy to handle and install, and they are guaranteed to hold their shape over time without sagging. Because stone wool is inorganic, it is naturally resistant to moisture and rot, ensuring your project is not only quiet and safe but also healthy and long-lasting. ## Features - PROFESSIONAL-GRADE SOUNDPROOFING: Achieve superior sound control with high-density 8 lb/ft³ stone wool. Its rigid structure is exceptionally effective at blocking airborne noise, making it the premier choice for home theaters, recording studios, mechanical rooms, and any space where quiet is critical. - ALL-IN-ONE THERMAL & VAPOR BARRIER: The integrated FSK (Foil-Scrim-Kraft) facing provides a built-in vapor retarder to prevent moisture transmission. It also acts as a radiant barrier, reflecting heat to improve the overall thermal performance and lower your energy costs. - FIRE RESISTANCE: Safeguard your property with non-combustible insulation. Rockwool can withstand temperatures up to 2150°F (1177°C) without melting or producing toxic smoke, providing an essential fire block in walls, ceilings, and around ductwork. - RIGID & DURABLE FOR EASY INSTALLATION: Engineered for demanding applications, the 8 lb density provides superior rigidity and compressive strength. These panels are easy to cut, will not sag or slump in cavities over time, and resist damage during installation, ensuring lasting performance. - WATER REPELLENT & INERT: Rockwool stone wool is inherently water repellent and inorganic, meaning it provides no food source for decay contributing to a healthier and more resilient building. - 5 Boards per box. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0B2YZNK6W | | Best Sellers Rank | #119,022 in Musical Instruments (See Top 100 in Musical Instruments) #2,230 in Recording Studio Acoustical Treatments | | Brand Name | BRB Products | | Coverage | 40 square feet | | Customer Reviews | 5.0 5.0 out of 5 stars (1) 5.0 out of 5 stars | | Item Dimensions L X W | 48"L x 24"W | | Item Thickness | 3 inches | | Item Type Name | Rockwool | | Item Weight | 56 pounds | | Manufacturer | Rockwool | | Manufacturer Part Number | 40 square feet | | Material Type | Wool | | Model Number | SL9603"FF | | Number Of Items | 5 | | Recommended Uses For Product | Insulating | | Unit Count | 1 Count | | Upc | 613497350611 | ## Product Details - **Brand:** BRB Products - **Item Thickness:** 3 inches - **Material:** Wool - **Product Dimensions:** 48"L x 24"W - **Recommended Uses For Product:** Insulating ## Images ![Rockwool 8# Density Foil-Faced Stone Wool Insulation Mineral Wool Panels, Batts - 3", 2'x4' (5) per Pack, Pro-Grade Acoustic Soundproofing, Thermal Barrier & Fire Block - Image 1](https://m.media-amazon.com/images/I/318h15vZ6ES.jpg) ![Rockwool 8# Density Foil-Faced Stone Wool Insulation Mineral Wool Panels, Batts - 3", 2'x4' (5) per Pack, Pro-Grade Acoustic Soundproofing, Thermal Barrier & Fire Block - Image 2](https://m.media-amazon.com/images/I/61ILYMJD5tL.jpg) ![Rockwool 8# Density Foil-Faced Stone Wool Insulation Mineral Wool Panels, Batts - 3", 2'x4' (5) per Pack, Pro-Grade Acoustic Soundproofing, Thermal Barrier & Fire Block - Image 3](https://m.media-amazon.com/images/I/61FZedHIaOL.jpg) ![Rockwool 8# Density Foil-Faced Stone Wool Insulation Mineral Wool Panels, Batts - 3", 2'x4' (5) per Pack, Pro-Grade Acoustic Soundproofing, Thermal Barrier & Fire Block - Image 4](https://m.media-amazon.com/images/I/61WXRsRjuyL.jpg) ![Rockwool 8# Density Foil-Faced Stone Wool Insulation Mineral Wool Panels, Batts - 3", 2'x4' (5) per Pack, Pro-Grade Acoustic Soundproofing, Thermal Barrier & Fire Block - Image 5](https://m.media-amazon.com/images/I/71oP4rjee9L.jpg) ## Available Options This product comes in different **Style** options. ## Frequently Bought Together - Roxul, Rockwool Mineral Wool Board, ProRox SL960 (8# Density), Click for Size Options - Zombiebox Generator Exhaust Extension Silencer Kit with Insulated Through-Wall Mounting Plate - Includes 3 Adapters - Fits All portable Generators - SunplusTrade 2" x 50' Black Exhaust Heat Wrap Roll for Motorcycle Fiberglass Heat Shield Tape with Stainless Ties --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/445170964-rockwool-8-density-foil-faced-stone-wool-insulation-mineral-wool](https://www.desertcart.ie/products/445170964-rockwool-8-density-foil-faced-stone-wool-insulation-mineral-wool) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-08-15*
