Insulation industry news from Global Insulation

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.

Romania: Knauf Insulation’s revenue grew by 40% year-on-year to Euro27.2m in 2022 from Euro19.4m in 2021. It attributed this to increased sales volumes and higher pricing, according to the Ziarul Financiar newspaper. The subsidiary of Germany-based Knauf acquired the Târnăveni glass wool insulation plant from Gecsat in mid-2022. It later announced plans for a Euro135m upgrade to the site including expanding the existing unit and building a new plant adjacent to it. Construction work on the project was schedule in start in January 2023.

Russia: TechnoNicol expects to commission its upgraded Khabarovsk stone wool insulation plant later in 2023. Local press has reported that the on-going upgrade involves replacement of the plant's rock melting furnaces and fibreisation chambers. When commissioned, the upgraded plant will produce insulation using a biopolymer bonding agent. The producer expects to export its products to the Japan and South Korea markets.

Austria: Austrotherm has invested Euro20m on an upgrade to its extruded polystyrene (XPS) production capacity at its Purbach insulation plant. The project added a production hall with new extrusion technology supplied by Germany-based KraussMaffei Group. The expansion has also created 20 new jobs at the site. A further upgrade to the plant will be built in 2023 when a photovoltaic system will be installed on the roof of the hall.

UK: Knauf Insulation has concluded a deal to acquire the Pilkington Architectural site next to its glass wool plant in St Helens. The purchase of the seven hectare area is part of a combined Euro46m production capacity expansion project at both the St Helens and Cwmbran plants that was previously announced in April 2022. At the St Helens plant the company plans to use the additional space storage space and better logistics arraignments.

UK: Denmark-based Rockwool has announced plans to replace natural gas used in its Bridgend stone wool insulation plant's combustion systems and curing ovens with green hydrogen produced on-site. Engineering company Marubeni Europower and consultancy Mott MacDonald will also be involved in the project. H2 News has reported that the work will rely on US$462,000 in government funding.

Rockwool's managing director Rafael Rodriguez said “The group has set ambitious decarbonisation targets, verified and approved by the Science Based Target Initiative, and in line with this, we are looking forward to enhancing our own understanding about the potential for green hydrogen use in our business.”

China/US: France-based Arkema has announced progress at two locations towards increasing the production capacity of its blowing agent product Forane 1233ZD. In China the group says its partner Aofan has started operation at a production plant. In the US at Calvert City, Kentucky the group has broken ground on the construction of an upgrade to a production line at its existing plant. The US$60m project is expected to be completed by early 2024. Both units are intended to increase the global availability of the Forane 1233ZD product.

The chemicals company is promoting the use of fluorinated liquid blowing agent due to its sustainability advantages. The product is used primarily in closed celled polyurethane foam for building insulation and cold chain applications. It also has applications for the thermal management of batteries in electric vehicles.

Romania: Knauf Insulation has begun mineral wool production at its recently acquired Tarnaveni plant in central Romania after investing Euro4m in upgrades. The investment covered the initial stages of modernisation at the Gecsat plant production line in Mures County, according to a Knauf press release.

A second stage of refurbishment began in September 2022. Once the entire investment plan is implemented, the Knauf Insulation factory in Tarnaveni will have an annual production capacity of about 60,000t/yr of mineral wool, with the aim of serving both domestic needs, as well as markets in Central and Eastern Europe.

Founded in 1918 in Tarnaveni as Ardeleana Glass Factory, former owner Gecsat started producing glass mineral wool at the site in 2007. Knauf announced that it was acquiring the glass mineral wool plant in January 2022 and became its owner in March 2022.

Germany: Heraklith has announced that its wood wool production plant in Simbach will be comprehensively modernised in 2023, alongside a significant increase in capacity. The focus of the planned investment is the moulding of the press line. Here, dimensionally accurate, single-layer lightweight panels and top layers for wood-wool multi-layer panels are created from wood-wool fibres and a mineral binding agent. The conversion work is currently planned for the second half of 2023. However, the exact schedule depends on the delivery situation of some key components.

“The modernisation of the system will ensure the high quality of our Heraklith products in the long term and also further increase occupational safety for our colleagues,” explained Rico Neumann, Director for Sales, Building Construction and Marketing in Germany. “The investment is a positive signal for the long-term prospects of the Simbach site and the future of our most important wood wool plant.”

Markus Uhl, Sales Manager Germany Heraklith Contract Business and Timber Construction, added “Our customers will benefit both from the additional production capacities and from the reliability of the new systems. We assume that our investment will have a significant impact on the rapid availability of our extremely popular wood wool products for underground car park ceilings and timber construction.”

South Korea: KCC Corporation is upgrading its Gimcheon and Munmak glass wool plants. A second production line is being built at the Gimcheon plant in Gyeongbuk and the production capacity of the existing production line is being increased at the Munmak plant in Gangwon-do. The upgrade projects will be completed in October and March 2023 respectively. Once finished the combined projects will increase the company’s total production of glass wool by 80,000t/yr.

KCC says that it is making the investment in inorganic insulation production capacity in response to revisions to local building regulations. It added that the law was changed in 2021 due to several fire-related incidents. The upgrades are also expected to reduce production costs per unit.
