Insulation industry news from Global Insulation

Austria: The insulation association Building Envelope and Insulation Industry (GDI) has reported a 1.9Mm³ decline in annual insulation sales since 2021. The hardest-hit segment was reportedly alternative insulation, with declines in cellulose, sheep wool and hemp. The OÖ Nachrichten newspaper has reported that the association attributed the decline to an on-going ‘property sector downturn,’ with homeowners stalling their refurbishment plans. The GDI praised the recent easing of lending guidelines and renewed submissions for reserved funding under the Sanierungsbonus insulation scheme.

GDI Chair Roland Hebbel said “A rebound in the construction industry is becoming increasingly urgent.”

Germany: BASF has completed a pilot, with Frankfurt-based housing society ABG and external thermal insulation composite systems producer Sto, testing an insulation board based on expandable polystyrene (EPS) containing recycled material. Around 10% of the polystyrene was replaced with a recycled substitute during the test. The results showed that the newly developed board met the same quality standards as standard market products. The sustainability targets of ABG was one of the key impetuses for the project.

BASF used its Neopor F 5 Mcycled product in the test. It is a graphite-containing expandable polystyrene granulate that contains 10% recycled material. The recycled material comes from mechanically recycled EPS waste. The aim is to other byproducts for the production of Neopor Mcycled in the future, such as EPS off-cuts from construction sites.

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.

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.

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."
