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."

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.

US: Saint-Gobain North America has started a program where windshield glass scraps are recycled and reused in the production of insulation. Waste glass from the company’s Saint-Gobain Sekurit’s unit at Garden Grove in California is sent to CertainTeed Insulation’s facility at Chowchilla, where it is use to make fibreglass insulation. Saint-Gobain is working with Shark Solutions on the project. The initiative started earlier in 2022.

US: Owens Corning has achieved inclusion on the Dow Jones Sustainability World Index 2022, topping the Building Materials category. The producer scored 88 out of 100 for sustainable performance across multiple indices. It recorded full marks for environmental reporting, materiality, recycling strategy, risk and crisis management and social reporting.

Owens Corning's senior vice president and chief sustainability officer David Rabuano said, "Earning placement on this index for the 13th consecutive year is a validation of the daily efforts of our colleagues across our operations globally. I am proud that their hard work and diligence in our sustainability efforts continues to be the driver of our leadership on the Dow Jones Sustainability Index - and an ongoing contributor to achieving our goals for 2030 and beyond."

Ireland: Kingspan’s sales rose by 33% year-on-year to Euro6.25bn in the first nine months of 2022. It said that insulated panel sales grew by 29% and insulation board sales grew by 48%. Panel sales were reported as holding up ‘reasonably well’ in the Americas, Germany and the UK but as being weaker elsewhere in Europe. Board sales increases were led by a rise in price.

US: Owens Corning recorded sales of US$7.48bn during the first nine months of 2022, up by 17% year-on-year from US$6.37bn in the first nine months of 2021. Its adjusted earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 24% to US$1.8bn from US$1.45bn. The group's insulation sales rose by 19% to US$2.76bn from US$2.32bn. The segment's higher selling prices reportedly offset accelerating energy, material and transport inflation.

During the year, the company transferred or sold all Russian assets, which had previously contributed US$100m in sales in 2021. Elsewhere, Owens Corning launched three new products during the third quarter of 2022 alone.

US: Hemp Inc.’s Hempcrete insulation panels have received approval for residential construction use in an appendix to the US Residential Building Code. Hempcrete insulation consists of hemp stalk hurd and lime. It is fire-resistant, moisture regulating and sequesters CO₂ naturally due to its hemp content.

Hemp Inc. operates a multi-purpose hemp processing plant in Spring Hope, North Carolina.

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.

France: Ireland-based Kingspan has closed its acquisition of Ondura Group. The group consists of light roofing producer Onduline, membranes producer CB and waterproofing systems producer Alwitra. It operates plants in four European countries, as well as Brazil, Malaysia, Turkey and the US. Law firm Clifford Chance, a long-term partner of Kingspan, advised the insulation group through the deal.

On 27 September 2022, Kingspan acquired waterproofing membranes producer Derbigum in neighbouring Belgium. Derbigum has recycled 30,000t of bitumen in its operations to date.

US: Knauf Insulation has appointed Valentin Salazar as the manager of its forthcoming glass wool insulation plant at McGregor in Texas. Other hires include Alex Garcia as Health, Safety & Environmental Manager and JT Tristan as Human Resources Manager. Crossland Construction was previously announced as the general contractors for the project in July 2022. The company expects to open its new unit in early 2024.
