The impact of our products
Rockwool insulation is one of the rare industrial products that saves more energy than it requires. Over 50 years, a typical Rockwool insulation product can save over 100 times more primary energy than was used for its production, transport and disposal. The energy balance becomes positive only 5 months after installation. For a product that insulates hot pipes, the energy payback can be less than 24 hours - the return on invested energy is more than 10,000-fold.

The energy pay-back is more than a 100-fold. The LCA fulfils the quality standards of the ISO 14000 series and has undergone third party scrutiny and peer review.
The impact of our production
Energy comprises a major part of our total fi nancial and environmental bottom-line. So energy efficiency improvements are top priority and have been so for many years. Energy efficiency is also the key to reducing other environmental impacts of production, such as CO2, NOx and SO2 emissions.
The melting process, where at temperatures above 1500°C diabase rock is turned into lava and then spun as fibres, is the most energy-intensive part of the Rockwool production process. The Rockwool Group has some of the world’s leading experts in energy efficient production of stone wool. This is clearly demonstrated when newly acquired factories are modernised with Rockwool know-how. Energy efficiency improvements of 50% per production unit have been achieved while at the same time enhancing product quality, environmental performance and delivery precision. Since 2001 energy effi ciency improvements of 10% have been obtained on Group level.
