Insulation industry news from Global Insulation

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.”

UK: Knauf Insulation UK & Ireland is preparing to build a €200m rock mineral wool plant to supply the UK market. The company is currently discussing with the authorities where the plant will be situated. The unit will have a production capacity of over 100,000t/yr and will use low-carbon electric melting technology. It is anticipated the additional capacity will become available in 2026.

Neil Hargreaves, Knauf Insulation’s Managing Director for Northern Europe, said "Following the €50m investment across our two UK glass mineral wool plants in 2023 - 2024, this represents another exciting development for the business and our valued customers, as well as a further sign of confidence from Knauf Group in the future growth of the UK and Northern European mineral wool markets. The investment represents a step change in the capacity, capability, and sustainability of our UK rock mineral wool solutions, whilst significantly contributing towards Knauf Group’s ambitious sustainability goals."

Kazakhstan: Russia-based TechnoNICOL has begun building its upcoming US$124m Karaganda insulation plant. Interfax Kazakhstan Newswire has reported that the plant will export 30% of its insulation to Russia. Additionally, it will export some insulation to China, Kyrgyzstan, Mongolia and Uzbekistan.

US: Kingspan Insulated Panels North America is building a new K-Roc mineral wool insulation plant in Mattoon, Illinois. The producer expects the plant to commence operations in early 2025. It will be equipped with a solar power plant and rainwater harvesting system, recycling system and electric vehicle charging stations. When operational, it will employ 50 people. Kingspan’s K-Roc mineral wool insulation offers a three-hour fire rating in wall applications and one-hour fire rating in ceiling applications.

Kingspan Insulated Panels North America president Alswinn Kieboom said "As a result of continued growth and optimism for the future, the addition of this new facility complements our existing footprint in North America, giving us better access to our customer base. We are looking forward to launching this new site and having a presence in the Midwest."

Belgium: Knauf Insulation has released its ‘Sustainability Journey: 2023 Highlights’ report. It reveals the company’s sustainability strategy achievements focusing on safety, employee engagement, decarbonisation and the circular economy.

The company reduced its absolute full-scope emissions for its mineral wool production by 8.2% year-on-year to 1.34Mt of CO₂e in 2022 from 1.46Mt in 2021, mainly due to a significant fall in Scope 2 emissions. it currently has a target to reduce its specific embodied carbon emissions by 15% from 2021 to 2025. The recycled content of its glass mineral wool products fell to 55% in 2022 from 64%, despite the company having a target of 65% by 2025. It explained that sourcing large volumes of recycled materials of sufficient quality had proved challenging in some markets. However, it did increase the recycled content of its rock mineral wool products to 13% from 11%, with a target of 25% set for 2024. It also reduced its total recordable incident rate by 8% to 5.9 from 6.4 against a target of below 5 for 2025.

Dominique Bossan, the chief executive officer for Europe, Middle East and Asia at Knauf Group, said “The report documents our progress towards achieving our 2025 sustainability targets. It shows the areas where we need to improve, celebrates where we have made positive progress and pays tribute to the hard work of our teams."

South Korea: KCC has started operating its new second 48,000t/yr glass wool production line at its Gimcheon plant. Chair Chung Mong-jin and chief executive officer Jeong Jae-hun attended a ceremony marking the achievement in late August 2023. The company says that the new line is the largest single one of its type in the country.

Indonesia: The Indonesian Safeguards Committee started an investigation into slag wool, rock wool and similar mineral wools (including intermixtures) in bulk, sheets or rolls from late July 2023. It scheduled a hearing in mid-August 2023 for interested parties - such as importers and exporters - to present their views and evidence on the matter.

A safeguard investigation seeks to determine whether increased imports of a product are causing, or threatening to cause, serious injury to a domestic industry. A World Trade Organisation member may take a safeguard action, including the temporary restriction of imports, only if the increased imports of the product are found to be causing, or threatening to cause, serious injury.

US: CertainTeed has completed an upgrade at its Athens glasswool insulation plant in Georgia. Equipment used in the production of loose-fill insulation has been updated, including modifications to the unit’s loose-fill recycling machine. In addition, the plant has installed several new pieces of equipment, including a new baler, water sub-metering system, three air compressors, efficiency pumps on cooling towers and a cooling wind fan. The modifications are expected to save over 7300MWh/yr of energy and 76Ml/yr of water, and reduce landfill waste by over 5000t/yr.

Jay Bachmann, Vice President and General Manager of CertainTeed Interior Products Group, said “The work of our insulation plant in Athens is the perfect example of what sustainability looks like for industrial manufacturing operations, where a series of small changes brought together can make a huge impact. I want to thank the entire Athens team for their success.”

The subsidiary of Saint-Gobain North America previously announced in late 2021 that it was spending US$30m towards building a new insulation production line at the Athens plant. At the time it said that increased production was scheduled to start in late 2023.

Denmark: Saint-Gobain’s subsidiaries Isover and Leca have started an agreement with waste management company Norrecco to recycle glass wool insulation. Under the new system, contractors will be able to return used and excess Isover glass wool to Norrecco's waste treatment stations at Prøvestenen in Copenhagen and at Agerskov in Southern Jutland. Norrecco will then pass the glass wool to Leca Denmark’s plant at Hinge near Randers. Here it will be used as a raw material in the production of lightweight expanded clay aggregate (LWA) products. LWA is used in a variety of applications such as insulation or as a structural filler. Leca added that LWA can be recycled repeatedly.

Mona Ammitzbøll Rasmussen, the Sustainability Engineer at Saint-Gobain Denmark, said "From the moment our glass wool leaves the factory, we want to support the idea that the material will one day return and be used in the production of new insulation materials, rather than ending up in landfills. It is an unnecessary waste that we need to eliminate as soon as possible."

Leca Denmark has the capacity to accept around 1000t/yr of used or excess glass wool from the Danish market. The company said that, although it represents a small portion of the total production, it reduces the need to extract a corresponding amount of natural clay, which is the primary raw material in its Leca LWA product. Isover is also working on publishing guides to better help contractors sort between the different types of mineral wool to assess purity ahead of potential recycling.

South Korea: KCC has signed a memorandum of understanding with the local government in Gimcheon concerning an upgrade to its glass wool plant. The company plans to invest around US$75m on building a second production line at the unit by the end of 2023. The project follows a similar upgrade at the Munmak glass wool plant in 2022.
