Insulation industry news from Global Insulation

India: Saint-Gobain has entered into an agreement to acquire Indian market leader glass wool insulation producer Twiga Fiberglass, local press has reported. Twiga Fiberglass has produced insulation as a licensee of Saint-Gobain's glass wool insulation technology since 2005.

Saint-Gobain previously acquired stone wool insulation producer Rockwool India in February 2022.

Ireland: Kingspan's consolidated sales rose by 28% year-on-year to Euro8.3bn in 2022 from Euro6.5bn in 2021. The group's profit after tax also rose, by 8% to Euro616m from Euro571m. Its turnover from insulation sales rose by 40% to Euro1.66bn, while its turnover from insulated panels sales rose by 23% to Euro5.18bn. Panel volumes were reportedly 'more challenged' during the second half of the year.

CEO Gene Murtagh said “The 2022 outturn was very satisfactory in the context of accumulating uncertainty over the course of a bumpy year, which saw a strong first half performance giving way to a more subdued environment in the second half." He added "Given the powerful combination of our global scale, the diversity of our end markets, our ability to grow organically and through acquisition, alongside our strong innovation pipeline and an ongoing societal drive for energy efficiency, we believe Kingspan is very well placed for continuing progress for the benefit of all stakeholders."

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.
