Insulation industry news from Global Insulation

Finland: Saint-Gobain Isover has commenced production at its upgraded Forssa glass wool insulation plant in Kanta-Häme. Financial Wire News has reported that production is powered by a 50:50 energy mix of biogas and hydroelectricity. The producer says that this will reduce the Forssa plant's CO₂ emissions by 1500t/yr.

Saint-Gobain Isover is Finland’s largest consumer of recycled glass, of which the Forssa plant uses 80% in its raw materials mix.

UK: France-based Saint-Gobain says that it will build a stone wool insulation plant in Melton Mowbray, Leicestershire, at the site of the former Holwell foundry. The plant will use electrical heat and be powered by renewable sources. When operational in 2027, it will have a capacity of 50,000t/yr and employ 250 people.

Ukraine: Horticulture company Green Wave Organic has developed a new peat-based substrate to replace mineral wool in vertical horticulture at its facilities in Zolochiv, Lviv Oblast. New Voices of Ukraine News has reported that Green Wave Organic recently received a €15,000 EU4Business grant from the EU.

Compliance officer Ivan Fryz emphasised the need to continue to innovate under challenging circumstances, with electricity prices double their April 2024 levels.

Spain: Saint-Gobain has launched a €40m expansion and upgrade to reduce CO₂ emissions by 70% at its Azuqueca insulation plant in Castilla-La Mancha. The producer will replace the plant’s existing furnace with a new electric one. When operational in early 2026, the upgraded line will expand the Azuqueca plant’s capacity by 40%. The furnace will run on renewable electricity sourced under a power purchase agreement signed with utilities provider Endesa in 2022.

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."

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."

Mongolia: Mongol Basalt produced 2248t of stone wool insulation in 2024, which it says helped Mongolians to reduce their energy consumption by 78GW. Nonetheless, the producer’s sales fell by 20%, amid a 35% drop in its prices.

During 2023, Mongol Basalt commenced construction of a new production line at its Ulaanbaatar insulation plant. The UB Post newspaper has reported that the company expects the upgrade to double its capacity to 50,000t/yr, and to introduce new energy-efficient solutions.

Italy: Saint-Gobain has entered into a 10-year power purchase agreement (PPA) with Switzerland-based utilities provider Axpo Holding. Under the agreement, Axpo Holding will supply 22GWh/yr of renewable electricity from a newly built wind farm in Puglia. The deal will fulfil 11% of Saint-Gobain's Italian energy needs across 10 sites.

The latest PPA with Axpo Italia is Saint-Gobain's fifth in Italy. Collectively, these will bring the group’s reliance on renewables in its Italian operations to 20%.

Finland: Metso has launched the Outotec Mineral Wool Furnace, an electric furnace for mineral wool production. The new model is based on Metso's established proprietary equipment, used in ferroalloy and slag cleaning applications. As part of Metso's Planet Positive offering, the furnace offers reduced CO₂ emissions, high plant availability, extended life and an easily customisable modular design for specific applications.

Technology director Tom Ronnberg said “Demand for insulation materials is growing due to tightening energy efficiency requirements. At the same time, the insulation material industry is aiming for better efficiency and carbon neutrality in their production processes.”

Europe: US-based Owens Corning has joined the European Alliance to Save Energy (EU-ASE). The producer said that its membership in the alliance will help in its drive for best practices in material innovation and energy efficiency in Europe.

Owens Corning’s Europe regional regulatory and sustainability senior counsel said “Owens Corning is honoured to join the EU-ASE. This is an exciting opportunity to strengthen our partnerships with key stakeholders and continue to build a sustainable future through material innovation. We are committed to the European Green Deal objectives and will continue to share best practices and knowledge across industries on key sustainability topics, such as energy efficiency, sustainability and digitalisation, while contributing to the green transition in Europe.”
