Insulation industry news from Global Insulation

North America: The Center for the Polyurethanes Industry (CPI) recorded total polyurethane (PU) production of 4.1Mt in North America in 2023. US Political and Economic Organizations News has reported that applications contributing towards the growth included continuous insulation and spray foam for air barriers.

Director Jason Sloan noted market challenges due to ‘shifts in demand and availability for raw materials,’ but said that producers were adapting to the market dynamics.

UK: The six-year public inquiry into the Grenfell Tower fire, which claimed 72 lives in 2017, has issued its final report, finding fault with ‘dishonest’ companies, as well as former governments and a disorganised response from the fire service. The inquiry criticised the role of cladding manufacturers, notably US-based Arconic, for its ‘systematic dishonesty’ in concealing the true fire hazards of its products. Arconic, which produced the Reynobond 55 polyethylene cladding used on Grenfell Tower, was accused of having hidden ‘very poor’ fire safety test results from the public and certification bodies. In the report, the cladding is described as ‘extremely dangerous’ when used in folded cassette form, and was ‘by far the largest contributor’ to the Grenfell fire.

The inquiry also named both Celotex and Kingspan as contributors to the incident. Celotex was accused of making ‘false and misleading claims’ by presenting its product to cladding contractor Harley Facades as being safe and suitable for Grenfell, even though ‘it knew that was not the case.’ Insulation producer Kingspan reportedly ‘misled the market’ by not revealing the limitations of its product, which was used on a small section of the building. In response to these findings, the inquiry has called for a revision in testing materials and designs for fire safety, advocating for transparency by making these test results publicly accessible. The findings of this inquiry lay the groundwork for potential criminal charges, with police and prosecutors indicating that investigations will continue until the end of 2025, and decisions on criminal charges expected by the end of 2026, according to a report by the BBC.

Kingspan said in a statement “We welcome the publication of today’s report which is crucial to a public understanding of what went wrong and why. It explains clearly and unambiguously that the type of insulation (whether combustible or non-combustible) was immaterial, and that the principal reason for the fire spread was the PE ACM cladding, which was not made by Kingspan. Kingspan has long acknowledged the wholly unacceptable historical failings that occurred in part of our UK insulation business. These were in no way reflective of how we conduct ourselves as a Group, then or now. While deeply regrettable, they were not found to be causative of the tragedy and Kingspan has already emphatically addressed these issues.”

A spokesperson for Celotex said “The publication of the Grenfell Tower Inquiry report marks the conclusion of the inquiry’s work and we are considering its contents with care. This review was a significant and thorough undertaking, and the results of that work were disclosed promptly and proactively to relevant stakeholders, including the Grenfell Tower Inquiry. Independent testing commissioned following the review demonstrated that the cladding system described in the Celotex RS5000 marketing literature met the relevant safety criteria. That system was substantially different to that used at Grenfell Tower. Decisions about design, construction and the selection of materials for the Tower were made by construction industry professionals.”

A spokesperson for Arconic subsidiary Arconic Architectural Products (AAP), which Building News reports supplied aluminium composite material used for the rainscreen at Grenfell Tower, said “The company respects the Inquiry process. AAP cooperated fully with the work of the Inquiry and will continue to engage with further legal processes. Together with other parties, AAP has made financial contributions to settlements for those affected, as well as to the restorative justice fund. Throughout the Inquiry, AAP has maintained a number of points: AAP sold sheets of aluminium composite material as specified in the design process. This product was safe to use as a building material, and legal to sell in the UK as well as the more than 30 other countries in which AAP customers purchased the product. We reject any claim that AAP sold an unsafe product. AAP regularly conducted tests of its materials using third-party testing bodies. Reports on these results were all publicly available, and AAP made these reports available to its customers. AAP did not conceal information from or mislead any certification body, customer, or the public.”

Romania: Knauf Insulation has announced the completion of its new 100Mm²/yr mineral glass wool plant in Târnăveni, scheduled for inauguration by the end of 2024. With an investment of approximately €140m, the facility has a capacity of 75,000t/yr of mineral glass wool. This output will meet both domestic and regional market demands and create 100 jobs.

Adrian Garofeanu, general manager of Knauf Insulation Romania and Bulgaria said “In the second half of 2024, we are inaugurating the new Knauf Insulation unit in Romania. It is a remarkable success of the team, which will turn Târnăveni into a key location on the map of the international production of mineral glass wool.”

Sweden: Paroc has broken ground on the conversion of its Hällekis mineral wool insulation plant from coke-fired production to the use of electric furnaces. The producer says that the upgrade will eliminate 80% of the plant’s CO₂ emissions. It is additionally installing new raw materials handling and filtration equipment at the plant. Work is scheduled for completion in 2027.

Nico del Monaco, Insulation President of US-based parent company Owens Corning, said "We have seen that the landscape for our industry in the Nordics is undergoing significant changes, with new CO₂ restrictions and expectations from customers. By proactively addressing these changes through projects like this, we can turn them into opportunities. This significant investment is an important step for not only our plant in Hällekis, but it also reinforces Owens Corning's mission to build a sustainable future through material innovation."

Ukraine: Construction firm Rauta recorded 15% year-on-year growth in the Ukrainian insulation sector’s domestic sales of insulated sandwich panels in the first half of 2024. Meanwhile, imports of the product dropped by 12% over the same comparison period. Consumption totalled 1Mm², in line with 2023 volumes. Business World News has reported that Rauta noted a shift from other panel types towards polyisocyanurate (PIR) core panels.

Construction activity remains mostly concentrated in Western Ukraine due to the on-going Russian invasion in other areas of the country, with investors reportedly remaining cautious. Ukraine’s construction market has declined by 60 – 70% from antebellum levels in 2021.
