Roxul AFB is a lightweight, semi-rigid batt insulation designed specifically for interior wall, floor, and ceiling applications. This stone fiber based insulation is made from natural stone and recycled content. It's a green 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 residential and commercial construction.
Room to room or floor to floor, when Roxul AFB is specified for interior wall or floor assemblies, better overall sound control and fire protection are achieved. Compared to other types of insulation, the stone fiber content of AFB provides increased density that effectively reduces airflow and essentially sound transmissions. Greater noise or sound control is further achieved when thicker AFB and gypsum board are used together. AFB thickness rages from 1.5" to 3.5".
Testing demonstrates the Roxul AFB inherently higher density and manufacturing process delivers dramatically better air flow resistivity compared to fiberglass. Higher air flow resistivity means better sound attenuation.
In residential and commercial applications, much of the sound or noise to be controlled is produced in low frequency or bass ranges. For residential, this noise includes conversations, television sets, radios and home theater surround sounds, dishwashers, laundry rooms, etc. For commercial, this noise includes conversations, telephones, projection/video equipment, and ventilation systems. In the lower 1/3 octave bands, tests have shown that Roxul AFB outperformed fiberglass insulation, providing more low frequency absorption when comparing acoustical testing at low frequencies.
Roxul AFB's combination of stone fiber and recycled content makes this insulation fire resistant. This non-combustible product does not develop smoke or promote flam spread when exposed to flame, making AFB a critical line of defense in fire protection. In fact, studies have proven that stone or mineral fiber insulations provide a 54% increase in overall fire resistance rating compared to non-insulated assemblies.
Roxul AFB will not absorb water or hold moisture. In fact, its stone fiber composition is ideal for repelling and draining water away from walls and studs, protecting them. AFB's fire resistance and sound control properties are never comprised by water or moisture. Ideally AFB will not corrode and it does not promote fungi or bacteria growth.
SAG FREE TIGHT FITS:
The higher density of AFB provides superior sag resistance and fit. Once installed AFB holds its shape without sagging or slumping in the wall cavity over time to consistently provide continuous fire protection and sound control.
AFB is an innovative insulation offering a world of green features that help developers earn LEED points across six construction categories. AFB's greenest features include: Natural, inorganic material with recycled content.
