Rockwool 8# Density Foil-Faced Stone Wool Insulation Mineral Wool Panels, Batts - 2" Thick, 2'x4' (7) per Pack, Pro-Grade Acoustic Soundproofing, Thermal Barrier & Fire Block

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.

• 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.
