Insulation industry news from Global Insulation

US: Hempitecture has inaugurated a hemp-based insulation plant in Jerome County, Idaho. The plant employs five people and produces insulation using hemp grown in Montana. The producer hopes to supply its flagship HempWool thermal insulation and other acoustic and continuous insulation products to major green building materials markets, including Denver, Los Angeles and San Francisco. It began developing hemp-based insulation in partnership with the University of Idaho with a US$207,000 grant from the Idaho state government in 2021.

Hempitecture CEO Mattie Mead said "We are ushering in the future of truly sustainable building materials."

UK: The Peatland Progress bog restoration project in Cambridgeshire will plant and harvest bulrushes for use as a raw material in alternative insulation production. The Evening Standard newspaper has reported that trials have successfully produced insulation from bulrushes in Germany and the Netherlands. Peatland Progress holds Euro9.08m in National Lottery funding. The project will rewet peat and restore wetland habitats over 120 hectares of the historic Fens.

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.

Australia: Malaysia-based PGF Capital is preparing to open three distribution centres at Brisbane, Perth and Sydney. The mineral wool insulation producer set up its new regional headquarters in Melbourne in the third quarter of 2022, according to the New Straits Times newspaper. The site at Brisbane is set to become fully operational in March 2023, the site in Perth in May 2023 and the site in Sydney is expected to be operational in the third quarter of 2023.

The expansion drive is part of a project to grow its business in Oceania. Another market that the company is targeting is South Korea. PGF Capital and its subsidiary PGF Insulation said it has started making modifications to its production line at Perai in Penang to meet the local market requirements. it plans to start supplying insulation products to the country later in 2023.

Finland: Metsä Group has invested in wood fibre insulation producer Fiberwood in a late seed funding round. The round was led by Metsä Group’s new business and research subsidiary Metsä Spring. It also included government financing from Business Finland.

Fiberwood is developing and manufacturing wood fibre insulation and packaging materials made from mechanical wood industry side streams. The Finland-based company was founded in 2019.

Karita Kinnunen-Raudaskoski, the Director of Technology and Product Development at Fiberwood, said “Since September 2022, in our first phase of production we have been able to produce commercial-sized insulation boards for testing. Next, we will build a continuous pilot line for production-scale product and process development. As no existing machinery and processes can produce our products, we need to invent new technology to do so.”
