Details

Rockwool AFB is a lightweight, stone wool acoustical fire batt insulation specifically designed for steel stud and wood stud interior wall and floor applications. AFB combines the benefits of fire resistance, sound absorption and durability together into a unique insulation product that will add value to your assemblies. See why AFB is the best mix of fire resistance, sound absorption, and durability an insulation has to offer.

Fire Resistance

AFB is non-combustible, can withstand temperatures up to 2,150°F and will not develop toxic smoke or promote flame spread, even when directly exposed to fire. AFB has the lowest possible flame spread/smoke development index of 0/0 when tested in accordance with ASTM E84.

AFB is a key component of several UL and Intertek listed fire partitions and is available in a number of different thicknesses to meet the needs of your project for both new construction and renovation. Take a look through the AFB product guide which contains a collection of fire rated wall assemblies, providing 1 hr, 1 ½ hr and 2 hr rated wall assemblies using Rockwool AFB.

Sound Absorption

AFB is specifically designed to reduce sound transmission and provides exceptional acoustic comfort when installed in a wall assembly. Insulation is a key first step in a complete acoustic solution that may also include components such as additional gypsum boards and resilient channels. The Rockwool Technical Services team is available to assist you in meeting your acoustic design goals.

Durability

The durability of AFB provides the optimal balance of rigidity and flexibility helping to make installations easy, fast, and efficient. The flexibility of the batt allows for simple insertion into the stud cavity, while the added rigidity and recovery of the product provides a complete fit into the assembly, minimizing gaps and compression to provide optimal and long-term performance of the wall assembly.
