Insulation industry news from Global Insulation

Russia: TechnoNICOL has installed a new glass furnace and polymerisation chamber at its Serpukhov glass wool plant in Moscow Oblast. AK&M News has reported that that the upgrade will expand the plant’s glass wool capacity to just under 2Mm³/yr and enable it to produce a total of 300 different types of insulation. TechnoNICOL is investing US$18m in the project, which uses equipment from Russian suppliers and is intended to reduce the sanctioned nation’s reliance on imports.

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.”

Argentina: The Ministry of Economy has removed anti-dumping tariffs imposed upon imports of glass wool from Mexico. The decision follows an investigation requested by Saint-Gobain, according to Forbes. The government placed a tariff of 67% on the products in 2012 and this was later renewed in 2018 at the prompting of Saint-Gobain Argentina. Reportedly Saint-Gobain reached a glass wool capacity utilisation rate of 93% in 2023 and the company covers two-thirds of the market.

Spain: URSA says it used 35,800t of recycled materials to produce glass wool and extruded polystyrene (XPS) products in 2023. Just under 70% of the raw materials used to manufacture glass wool and XPS came from waste streams from sectors including car and food manufacture.

The subsidiary of Belgium-based Etex has also been granted a new Environmental Quality Assurance certifying that it recycles at least 60% of the raw materials used in its glass wool. Other recent sustainability milestones include an increase in the amount of recycled material the company uses in its packaging. Glass wool products from its El Pla de Santa Maria plant contain a primary sheet with a minimum of 50% of recycled plastic and the packaging of its XPS range includes a primary sheet with up to 30% of recycled plastic.

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.

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.

UK/Ireland: Knauf Insulation UK & Ireland has launched ‘OmniFit Slab 32’, a 32 lambda glass mineral wool insulation slab product for use in light steel frame systems (SFS) as part of a rainscreen façade or other external wall build-ups.

Liliya Luke, the Glass Mineral Wool Product Manager at Knauf Insulation, said “We have launched OmniFit Slab 32 to help our customers deliver the low U-values required, without compromising on fire safety, acoustic performance or sustainability.” He added, “Specifiers can now optimise their rainscreen façade systems by adding the benefits of glass mineral wool to their build-up - delivering acoustic performance, and reduced embodied carbon compared to rock-only solutions, with an insulation specification that remains completely non-combustible.”

The new product is primarily designed for use with ‘Rocksilk RainScreen Slab’ when used in rainscreen applications, and is suitable for use in the external wall systems of all residential buildings over 11m tall and relevant residential buildings over 18m tall. It is the latest addition to Knauf Insulation's OmniFit range of glass mineral wool roll and slab products.
