## 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.

Review: Works - Easier than old school pink insulation. Cut easily with a box cutter. Easy for patches and or odd spaces
Review: Love this stuff! - Very easy to work with. Cuts with ease but sturdy enough to stay where you want it.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works
*by J***L on August 25, 2024*

Easier than old school pink insulation. Cut easily with a box cutter. Easy for patches and or odd spaces

### ⭐⭐⭐⭐⭐ Love this stuff!
*by W***E on August 13, 2022*

Very easy to work with. Cuts with ease but sturdy enough to stay where you want it.

### ⭐⭐⭐⭐ Good product, but does not come with foil
*by K***. on March 17, 2023*

The insulation panels do not have foil on them as advertised. That being said, they did a great job of quieting down a small office space (laid on top of ceiling drop tiles) that has a loud HVAC run above it. Easy to cut and place.
