Roxul AFB
AFB® is a light-weight, semi-rigid stone wool batt insulation used for superior sound absorbency and fire resistance.
Applications:
This product is designed for interior wall and floor applications.
Properties:
- Non-combustible stone wool insulation with melting point of approx. 1177°C (2150°F)
- Does not promote smoke or flame spread when exposed to flame
- High density for reduced airflow and sound transmissions
- Water and moisture resistant; does not absorb moisture to maintain insulating value
- Sag-free, tight fits for consistent fire and sound performances
- Range of thicknesses for retrofit and new construction applications
- Variety of wall and floor system configurations available – contact Roxul
- Does not rot, promote mildew, fungi, or bacteria, or sustain vermin
