Acoustical Fire Batt Insulation Acoustical Fire Batt Insulation for Commercial & Interior Partition Walls.

Batt insulation that ghts both re and noise. ROXUL AFB ROXUL AFB is a lightweight, batt insulation specifically designed for steel stud interior wall and floor applications. ® This stone wool insulation is made from natural stone and recycled content. It’s a sustainable product that provides superior sound absorbency and fire protection for overall occupant comfort and safety. That’s why AFB is quickly becoming the insulation of choice for today’s green builders in commercial and industrial construction. AFB – Acoustically Better Sound Transmission Class (STC) values don’t take into account...

Features and benets that set AFB apart. ® Fire Resistant Water Repellent ROXUL AFB is non-combustible and will not develop toxic smoke or promote flame spread, even when directly exposed to fire. AFB will therefore not add fuel to an existing fire, making it ideal for use in high occupancy buildings. Studies have shown that mineral wool insulated rooms provide a 54% increase in overall fire resistance rating compared to non-insulated rooms. ROXUL AFB will not absorb or hold water and will not promote mold or fungi growth. It has superior drying potential, effectively managing moisture in...

Acoustical Fire Batt Insulation Fast, Easy Installation The higher density of AFB provides superior sag resistance and fit. Other insulations may sag or slump over time with the settlement or the vibrations of interior doors opening and closing. This creates gaps that will allow sound to travel through. AFB holds its shape without sagging or slumping in the wall cavity over time to consistently provide continuous fire protection and sound control. ® Working with ROXUL insulation is a breeze. Simply cut with a serrated knife for quick and efficient installation between studs, around...
