FABROCK™ Wrap

FABROCK™ Wrap is a light density insulation that is available in rolls instead of batts. Engineered to be fabricated into OEM applications requiring insulation flexible enough to be wrapped around something while still maintaining its excellent fire, thermal and sound absorbing properties.

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
  • Denser composition provides excellent sound control
  • Outstanding thermal resistance
  • Dimensionally stable water and moisture resistant
  • Does not promote growth of fungi or mildew
