ROCKBOARD® 40/60/80

ROCKBOARD® is a premium multi-purpose board insulation to be used in walls, ceilings, and floors for acoustic and thermal applications including insulating mechanical or utility rooms, adding also a barrier to noise and fire. These products are available in various densities to support different applications.

  • Fire resistant, non-combustible product with a melting point of approximately 2150°F (1177°C)
  • Water and moisture resistant, repels water
  • Does not rot, promote mildew, fungi, or bacteria
  • Unique directional fiber structure provides excellent sound control
  • Provides superior compressive strength for job site durability
  • Easy to install, cut, shape, and fabricate
  • Fabrication at different densities maintains fire, water, and thermal properties
  • Offered faced with reinforced foil
  • ROXUL can contribute to earning LEED® points
