Hardrock

To provide flexibility in design, cost and usage of membrane roofing system, ROCKWOOL roofing boards offer three different types of roofing insulation system to allow owners, designers and installers to achieve the desired performance of an ideal roof.

ROCKWOOL flat roof insulation solutions are specially designed for membrane and metal roof systems.

ADVANTAGES:

  • Offers high resistance to compression and point loading to facilitate periodic maintenance of roof
  • Non-combustible and can withstand at least 1000°C without melting as per ASTM E749
  • Made of stone, therefore the thermal coefficient of expansion of the boards are virtually zero
  • The open fibre structure provides excellent sound absorption properties
  • Compatible to all types of roofing membranes.
