US: Johns Manville (JM) plans to build a new blowing wool production line at its Winder glass wool plant in Georgia. Construction is expected to start early in 2026 and the new line will be operational in mid-2027. When this project is complete, JM will employ more than 350 people in Winder.

“Climate Pro insulation continues to see strong growth and demand in the market,” said Bob Wamboldt, president and CEO of Johns Manville. The new production line is intended to give JM easier access to Central and East Coast markets in the country.

UK: Rockwool has submitted a Section 73 application to Birmingham City Council in support of its plans to build a factory at a site in Peddimore, Minworth. The plant would be only its second in the UK. The application requests permission to vary some of the details in the current planning permissions at Peddimore to suit Rockwool's specific proposal. If approved, Rockwool will then submit a more detailed reserved matters application later in 2025 or early 2026. Once detailed plans are developed there will be another round of community consultation. Rockwool hopes that construction can begin in 2026, with production starting in 2029.

Rockwool's proposed new factory will feature proprietary electric melting technology and boost supply capacity for UK and Ireland customers while also supporting its global sustainability plans. The Peddimore site at Minworth has been designated specifically for manufacturing and logistics uses and is part of a long-running regeneration and development project.

Rockwool’s UK and Ireland managing director Nick Wilson said "Since we announced our intentions to expand the business into the West Midlands, we have had an opportunity to share our plans with the community and are very grateful to those who have provided feedback. We are taking all feedback into consideration as we develop the plans and have included the community's observations so far in our Section 73 application to the council. We look forward to meeting with community members again in the coming months."

Germany: Saint-Gobain subsidiary Isover has announced the upcoming closure of the glass wool line at its Bergisch Gladbach plant in North Rhine-Westphalia. Energate Messenger News has reported that this is due to a local homebuilding ‘slump’ and reduced export volumes. As a result, Isover will cancel a planned green hydrogen plant project at the site.

Isover will now relocate ‘part of the production lost’ from Bergisch Gladbach to its Speyer plant in Rhineland-Palatinate.

Canada: Saint-Gobain Canada has appointed Jean-Claude Lasserre as its CEO, effective 1 April 2025. Lasserre brings over 30 years of experience working for Saint-Gobain across multiple continents, most recently serving as Saint-Gobain Surface Solutions CEO in France. Lasserre succeeds Julie Bonamy, who oversaw US$2.77bn in strategic acquisitions for Saint-Gobain Canada, including of metal products company Bailey Group of Companies, roofing company Building Products of Canada and siding products company Kaycan.

Lasserre said "My primary focus will be to connect with our customers and support our teams as we continue our work to offer a complete portfolio of building products with our recent acquisitions, while reinforcing our commitment to sustainable construction. We are eagerly anticipating the completion of North America's first zero-carbon wallboard plant in Sainte-Catherine, Quebec, and the imminent launch of CarbonLow drywall."
