ROCKWOOL insulation – where ordinary insulation can’t perform

Throughout Australia and across the globe,  ROCKWOOL stone wool meets the highest demands of Acoustic, Fire, Thermal  and Moisture control.


ACOUSTIC – From the Sydney Opera House to stadiums and recording studios around the world, high performance  ROCKWOOL stone wool effectively absorbs sound across the entire audible range.






FIRE – After the tragedies of many lives lost at sea over the last century due to onboard infernos, the marine industry created one of the strictest tests known to eliminate products that are labelled ‘fire resistant’, ‘fire retardant’, or ‘fireproof’ to only certify materials that under no circumstances can burn; that are non-combustible.

Today, the International Convention for Safety of Life at Sea continues to set the highest fire performance standards in the world. ROCKWOOL stone wool performs at the elite level of meeting these standards, keeping 9000 people safe onboard the world’s largest cruise ship – MS Harmony of the Seas.




THERMAL – Nowhere is thermal control more critical than our power stations, gas plants, oil platforms and processing plants. At temperatures up to 650°C, ROCKWOOL stone wool performs as the backbone of industrial efficiency.





MOISTURE –  Used in multi-story office towers and other high rise buildings, ROCKWOOL stone wool is a key moisture control material in Europe’s tallest building, The Shard, in London.

Wind and rain loads on high rise towers can be extreme because there is no protection from neighbouring buildings, trees and fences. The outside wall – a rain screen wall – must have excellent weatherproofing and dampness performance.

ROCKWOOL stone wool is used for these applications.  The stone wool insulation provides not only thermal insulation, but also acts as a critical part of the moisture barrier – keeping the inside of the building dry.

High rise buildings demonstrate that ROCKWOOL stone wool delivers the performance needed for critical building applications.High rise rain screen walls must last as it is very difficult and extremely expensive to fix the façade if it fails.


Since the beginning in 1937, the ROCKWOOL Group has developed into a global company operating 28 stone wool factories and 7 other factories on three continents. At present, the Group employs 10,601 highly skilled individuals.

  • In 1937 the first stone wool production starts in Denmark, and Sweden and Norway soon follows.
  • At the beginning of the 1940s, stone wool production only constitutes a small part of the parent company’s turnover, and during World War II stone wool activity is especially low. However, ever more efficient management and production processes as well as a high degree of attention to research and development paves the way for a gradual expansion of stone wool activities.
  • In 1954 production starts in Germany as the first factory outside Scandinavia.
  • Further expansion in Europe takes place during the 1960s and 1970s. ROCKFON acoustic products are introduced already in 1962, and in 1969 the special GRODAN water-absorbing mineral wool product substituting soil or sphagnum in green houses is added to the product range.
  • In 1985 ROCKPANEL external cladding boards are introduced, and LAPINUS with focus on special fibres is established in 1991.
  • After the fall of the Iron Curtain the ROCKWOOL Group starts establishment itself in Eastern Europe with among others, when the largest stone wool factory in the former DDR is bought in 1991. In 1993 Poland’s largest stone wool factory is acquired, and in 1999 the biggest stone wool factory in the Russian Federation.Eastern expansion is followed up in 1999 by an expansion towards the Southern European markets as well, and in 2000 a newly-built factory in Spain is inaugurated.
  • Also In 2000, the ROCKWOOL Group starts its expansion in the Far East with the acquisition of a factory in Malaysia.



“We need to continue working hard to produce even better products and leaving a smaller footprint in the process – that includes thinking sustainability into our products, operations, and R&D as well.”


The ROCKWOOL Group’s production of insulation materials in 2009 led to emission of 2.1 million tons of CO2.


The lifetime savings resulting from the use of the insulation materials sold in 2009 will amount to more than 4,000 million tons of CO2.
