Insulation industry news from Global Insulation

US: Owens Corning’s sales of insulation grew by 2% year-on-year to US$1.82bn in the first half of 2023 from US$1.79bn in the same period in 2022. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 9.5% to US$427m from US$390m. The group noted that insulation sales fell year-on-year in the second quarter of 2023 due to lower volumes, although this was partially offset by price rises and changes to its product mix. Overall, the company’s composites sales fell in the first half of 2023, leading to a slight drop in sales to US$4.89bn and a decline of 4% in adjusted EBITDA to US$1.15bn.

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.

Europe: Ireland-based Kingspan has signed an agreement with Germany-based wood products group Schramek to acquire a 51% stake in wood-based insulation producer Steico for an initial Euro251m. The Irish Times newspaper has reported that the group may pay more, if Steico reaches agreed-upon profitability thresholds. The agreement includes an option for Kingspan to also purchase a further 10% stake. Steico operates 27 insulation lines across four plants in Poland and France.

Kingspan CEO Gene Murtagh said “The acquisition of a majority stake in Steico represents an exciting next step in our strategy to provide the full spectrum of insulation products. Its suite of wood-based building envelope solutions broadens our ability to enable our customers to meet their sustainability and energy performance needs. Kingspan’s global routes to market, paired with our drive to innovate and widen the applications of Steico’s current technologies, are key to our plans to bring Steico bio-based solutions to the next level.”

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.

Belgium: PU Europe has issued a statement to the relevant European bodies responsible for fluorinated gases (F-gases) emphasising the role of low global warming potential (GWP) of F-gases in insulation foam applications.

The association has suggested that, instead of total ban of F-gases, a lowering of the threshold should be considered as an alternative. In its view a lower threshold would allow the users of thermal insulation to continue to benefit from products made from closed-cell polyurethane foam. It warned that a ban on the use of low GWP F-gases in insulation foam would have “significant implications for the Renovation Wave, as approximately 80% of the buildings that will exist in 2050 have already been constructed.” PU Europe emphasises the need to find solutions that strike the right balance between addressing operating greenhouse gas emissions from the existing building stock and controlling low GWP F-gases.

The European Commission proposed in early 2022, as part of its so-called 'fit for 55' package, to further reduce emissions of F-gases. It wants to change the existing quota system, gradually reducing the supply of hydrofluorocarbons to the European Union market to 2.4 % of 2015 levels by 2048.

PU Europe was founded in 1981 as BING to become the single European voice for the polyurethane insulation industry. The association represents insulation producers, raw material suppliers and component manufacturers from eleven countries with activities covering the entire continent.
