Rockwool panels are well known in the industry for fire-resistant properties. They are made from stone wool which forms the core insulation panel. This layer is sandwiched between two outer metal sheets.
The stone wool insulation material is compressed into dual-density rigid boards. The exterior surface of the insulation board is compressed more than the rest of the board. So the outer surface is stronger and offers higher compressive strength in the insulation system
There are some major benefits of Rockwool panels as regards their insulation. They are listed below:
