AFB Acoustic Fire Batt Insulation
ROCKWOOL AFB® is a lightweight, acoustical fire batt stone wool insulation specifically designed for steel stud and wood stud interior wall and floor applications.
Its superior sound absorbency and fire protection contribute to the overall comfort and safety of occupants. AFB is specifically designed to reduce sound transmission and provides exceptional acoustic comfort when installed in a wall assembly with gypsum boards and resilient channels.
AFB is non-combustible and will not develop toxic smoke or promote flame spread, even when directly exposed to fire. This helps to provide valuable extra time for people to reach safety and for fire services personnel to control the spread.
AFB is a key component of many tested fire-rated partitions and assemblies with tested STC ratings and is available in a number of thicknesses to meet the requirements of both retrofit and new construction applications.
Easy to install, AFB is an optimal balance of rigidity and flexibility helping to make installations easy, fast, and efficient.
