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.

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.

Denmark: Rockwool says that high construction and renovation activity in the residential sector mainly drove its insulation sales in 2021. Insulation business sales grew by 20% year-on-year to Euro2.29bn in 2021 from Euro1.91bn. Its earnings before interest and taxation (EBIT) rose by 17% to Euro275m from Euro236m. Strong growth was reported in Europe, solid sales in North America but some parts of China and elsewhere in Asia were negatively affected by coronavirus-related closures of some markets. The producer commented that its insulation sales increased ‘significantly’ in 2021 even compared to 2019 before the coronavirus pandemic started. However, it warned that “sales prices and productivity gains did not fully offset the accelerating inflation on production materials, energy and logistic costs.”

“The surprising speed of the 2021 economic rebound also brought challenges, including inventory and material shortages in some markets as well as logistics challenges that required creative solutions. Special thanks go to our customers for their patience and especially our people working in the factories and across the commercial, technical, procurement, and support teams, who worked together to reduce customer delays,” said chair Thomas Kähler and chief executive officer Jens Birgersson in a statement. Overall, group net sales grew by 19% to Euro3.09bn from Euro2.60bn. EBITDA increased by 15% to Euro602m from Euro522m.

Luxembourg: Armacell recorded consolidated net sales of Euro591m in 2020, down by 8% year-on-year from Euro644m in 2019. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) fell by 10% to Euro120m from Euro134m. During the year, the company completed a polyethylene terephthalate (PET) foaming line expansion in Suzhou, China, built an elastometric foams plant in Cheonan, South Korea and consolidated its Italian insulation activities at a new facility in Turin. It also made strategic investments in diversified areas.

President and chief executive officer Patrick Mathieu said, “In a complex and challenging environment our business model again proved resilient. With our global reach and multi-segment activity, we ended the year in relatively good shape. We took the appropriate measures to navigate changing circumstances and ensure we come out of the pandemic stronger than before. Our utmost priority was always to safeguard the health of our employees, maintain operations and continuously support our customers.” He added, “After the successful closure of our capital market refinancing in February 2020, our shareholders PAI Partners and KIRKBI expressed their commitment to our on-going growth strategy. In 2021, we look forward to partnering with our customers in adding value to their businesses.”

Denmark: Rockwool recorded net sales of Euro2.60bn, down by 4% year-on-year in local currency terms. Profit for the year fell by 12% to Euro251m. Sales were supported in regions where construction was able to remain active throughout the coronavirus lockdowns. The company noted a strong recovery in the fourth quarter of 2020.

Chief executive officer Jens Birgersson said, “Looking back on a turbulent year, we are proud of how well our colleagues handled the many challenges. Our teams ensured employees were safe while quickly adjusting operations, sales and service to match the changing needs of our customers.”

The company plans to make Euro370m of investments, excluding acquisitions in 2021. Planned investments include a new plant in the US and a plant relocation in China, in addition to capacity expansions for its Rockfon and Grodan stone wool businesses.

The group said, “The underlying medium to long-term structural growth drivers for stone wool products are even stronger today than at the start of 2020. On top of fundamental trends like urbanisation and increasingly tighter building regulations, we expect that several other trends will continue driving growth in our business. For example, the growing focus on energy efficiency, fire safety and circularity continues to influence the decisions of consumers, the building industry and policymakers, with the pandemic accelerating these trends in multiple ways.”

US: Stepan has recorded a first-half income before tax of US$63.4m, up by 15% year-on-year from US$55.2m in the first half of 2020. Net sales were US$910m, down by 5.4% year-on-year from US$962m. Polymer sales, which includes sales of Stepan’s rigid foam insulation polyols, fell by 20% to US$112m from US$141m due to lower North American and European demand, “reflecting Covid-19 construction project delays,” according to the company. This was partly offset by increased sales volumes of 41% from its China division.

China/Japan: Researchers from Kyoto University, the University of Tokyo in Japan and Jiangsu Normal University in China have developed a new material that can selectively capture carbon dioxide (CO₂) molecules and convert them into ‘useful’ organic materials, including a precursor for polyurethane. The research project has been described in the journal Nature Communications.

The material is a porous coordination polymer (PCP, also known as a metal-organic framework), a framework consisting of zinc metal ions. The researchers tested their material using X-ray structural analysis and found that it can selectively capture only CO₂ molecules with ten times more efficiency than other PCPs. The material has an organic component with a propeller-like molecular structure, and as CO₂ molecules approach the structure, they rotate and rearrange to permit CO₂ trapping, resulting in slight changes to the molecular channels within the PCP. This allows it to act as molecular sieve that can recognise molecules by size and shape. The PCP is also recyclable; the efficiency of the catalyst did not decrease even after 10 reaction cycles.

After capturing the carbon, the converted material can be used to make polyurethane, a material with a wide variety of applications including insulation materials.

Germany: Armacell has recorded earnings before interest, taxes, depreciation and amortisation (EBITDA) in the first half of 2019 of Euro63.4m, up by 29.2% year-on-year from Euro50.6m in the six months to 30 June 2018.

Armacell recorded half-year sales of Euro322m, up by 6.3% from Euro303m. CEO Patrick Mathieu notied the strong performance of both advanced insulation and engineered foams. The first half of 2019 was notable for an increase in Armacell’s Chinese polyethylene terephthalate (PET) production capacity and a commercial cooperation agreement in April with Thermaflex in Russia.

China/Germany: German companies Evonik and ThyssenKrupp Industrial Solutions have granted a licence to Zibo Qixiang Tengda Chemical for the use of its hydrogen peroxide to propylene oxide (HPPO) technology in China. Qixiang Tengda Chemical will build a propylene oxide plant in Shandong province and Evonik has licensed the production of hydrogen peroxide for the exclusive supply of the plant. Evonik and ThyssenKrupp Industrial Solutions have also entered into a long-term agreement for the supply of the respective HPPO catalyst. Propylene oxide is used mainly for the production of polyurethane foams, including those used in insulation for buildings.

“We’re proud of having gained Qixiang as a new strategic partner. With environmental awareness on the rise in China, HPPO is the technology of choice for sustainable production of propylene oxide because it produces no major by-products apart from water,” said Claus Rettig, the chairman of the board of Evonik’s Resource Efficiency division.

Planning work for the new Qixiang Tengda plant is scheduled to start in mid-August 2019 with commissioning expected for the first half of 2022. Qixiang Tengda, a chemical manufacturer, is part of Cedar Holdings Group.

China: A study by researchers from Australia's Commonwealth Scientific and Industrial Research Organisation and Britain's University of Bristol says that the provinces of Shandong and Hebei are the source of a rise in trichlorofluoromethane (CFC-11) emissions. It attributed about 40% to 60%of in the rise in CFC-11 since 2013 to this region, according to Reuters. After studying atmospheric data from South Korea and Japan they estimated that CFC-11 emissions from eastern China during the 2014 - 2017 period were around 7000t/hr higher than 2008 - 2012.

Previously in mid-2018 an investigation by the Environmental Investigation Agency (EIA) speculated that the widespread use of CFC-11 by Chinese rigid polyurethane (PU) foam producers might be the source of the reported rise of emissions.

China launched an inspection campaign into 3000 foam manufacturers in 2018 and promised to punish any violations of the Montreal Protocol treaty. The Ministry of Ecology and Environment said in March 2019 that it had shut down two manufacturing areas that produced CFC-11. It added that its investigation into PU foam makers had not found any large-scale usage so far but that producers may be getting better at hiding their operations. It also noted that there was ‘uncertainty’ in published research and called for better detection mechanisms.
