Insulation industry news from Global Insulation

Sweden: Paroc has broken ground on the conversion of its Hällekis mineral wool insulation plant from coke-fired production to the use of electric furnaces. The producer says that the upgrade will eliminate 80% of the plant’s CO₂ emissions. It is additionally installing new raw materials handling and filtration equipment at the plant. Work is scheduled for completion in 2027.

Nico del Monaco, Insulation President of US-based parent company Owens Corning, said "We have seen that the landscape for our industry in the Nordics is undergoing significant changes, with new CO₂ restrictions and expectations from customers. By proactively addressing these changes through projects like this, we can turn them into opportunities. This significant investment is an important step for not only our plant in Hällekis, but it also reinforces Owens Corning's mission to build a sustainable future through material innovation."

UK: Knauf Insulation UK & Ireland is preparing to build a €200m rock mineral wool plant to supply the UK market. The company is currently discussing with the authorities where the plant will be situated. The unit will have a production capacity of over 100,000t/yr and will use low-carbon electric melting technology. It is anticipated the additional capacity will become available in 2026.

Neil Hargreaves, Knauf Insulation’s Managing Director for Northern Europe, said "Following the €50m investment across our two UK glass mineral wool plants in 2023 - 2024, this represents another exciting development for the business and our valued customers, as well as a further sign of confidence from Knauf Group in the future growth of the UK and Northern European mineral wool markets. The investment represents a step change in the capacity, capability, and sustainability of our UK rock mineral wool solutions, whilst significantly contributing towards Knauf Group’s ambitious sustainability goals."

Mongolia: Mongol Basalt produced 2248t of stone wool insulation in 2024, which it says helped Mongolians to reduce their energy consumption by 78GW. Nonetheless, the producer’s sales fell by 20%, amid a 35% drop in its prices.

During 2023, Mongol Basalt commenced construction of a new production line at its Ulaanbaatar insulation plant. The UB Post newspaper has reported that the company expects the upgrade to double its capacity to 50,000t/yr, and to introduce new energy-efficient solutions.

Italy: Saint-Gobain has entered into a 10-year power purchase agreement (PPA) with Switzerland-based utilities provider Axpo Holding. Under the agreement, Axpo Holding will supply 22GWh/yr of renewable electricity from a newly built wind farm in Puglia. The deal will fulfil 11% of Saint-Gobain's Italian energy needs across 10 sites.

The latest PPA with Axpo Italia is Saint-Gobain's fifth in Italy. Collectively, these will bring the group’s reliance on renewables in its Italian operations to 20%.

Finland: Metso has launched the Outotec Mineral Wool Furnace, an electric furnace for mineral wool production. The new model is based on Metso's established proprietary equipment, used in ferroalloy and slag cleaning applications. As part of Metso's Planet Positive offering, the furnace offers reduced CO₂ emissions, high plant availability, extended life and an easily customisable modular design for specific applications.

Technology director Tom Ronnberg said “Demand for insulation materials is growing due to tightening energy efficiency requirements. At the same time, the insulation material industry is aiming for better efficiency and carbon neutrality in their production processes.”

Europe: US-based Owens Corning has joined the European Alliance to Save Energy (EU-ASE). The producer said that its membership in the alliance will help in its drive for best practices in material innovation and energy efficiency in Europe.

Owens Corning’s Europe regional regulatory and sustainability senior counsel said “Owens Corning is honoured to join the EU-ASE. This is an exciting opportunity to strengthen our partnerships with key stakeholders and continue to build a sustainable future through material innovation. We are committed to the European Green Deal objectives and will continue to share best practices and knowledge across industries on key sustainability topics, such as energy efficiency, sustainability and digitalisation, while contributing to the green transition in Europe.”

Denmark: Rockwool’s net sales grew by 27% year-on-year to Euro3.91bn in 2022 from Euro3.09bn in 2021. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 6% to Euro638m from Euro602m. The group reported a strong start to 2022 with high demand for its stone wool insulation products. In the second half of the year it noted a decline in construction activity in key markets. However, it increased its prices leading to increased sales. By region the group said that sales grew in Europe and Asian markets, were flat in the US and declined in China.

Chief executive officer Jens Birgersson said, “Looking forward, we expect construction activity to continue slowing down in the coming period. We anticipate the energy efficiency agenda in both Europe and North America will accelerate renovation rates in the mid-term and create higher demand for our circular and non-combustible stone wool. We will continue to invest in more capacity to support our long-term growth”.

Together with the group’s chair Thomas Kähler, he also defended the company’s decision to continue the ownership of a subsidiary in Russia. “If we were to depart Russia, our factories and the intellectual property rights to our unique technology would most likely be nationalised or otherwise transferred to local players. Since the factories operate independently of our head office, they would continue to operate - just under different ownership. It therefore remains our view that retaining the business in Russia is the least bad option available to us. And of course, we will continue to comply with all international sanctions.”

Rockwool said that it had added production capacity for its Grodan agricultural stone wool range at its plant in Toronto, Canada and capacity for its Rockfon stone wool ceiling panel range at its Cigacice plant in Poland. In China it had opened a new plant at Qinyuan in December 2022 to replace its mineral wool unit at Guangzhou, which closed in September 2022. It also reported that plans to build a new stone wool plant at Soissons in France had been delayed due to a local legal challenge. Notable upgrades in 2022 included the start of a conversion project to electric melting technology from fossil fuels at the Flumroc plant in Switzerland, with a commissioning date scheduled for 2024. This project follows a similar one at the Moss plant in Norway that was completed in 2020.
