Insulation industry news from Global Insulation

UK: Rockwool subsidiary Wetherby Wall Systems has launched SOQEL A2, an external wall insulation system for use below damp-proof course. The system integrates Rockwool’s Coverrock X-2 pre-coated insulation with Heck K+A SL coating and Heck CER mesh. Specification Online News has reported that the system complies with the A2-s1,d0 UK fire standard for buildings over 11m tall.

Technical director Joe Ragdale said “We have worked alongside our Rockwool sister company Heck in Germany to launch this innovative system into the UK market. This solution provides architects and contractors working on remediation projects with a compliant, durable, and efficient way to enhance building safety.”

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."

US: Rockwool has approved a US$100m investment in the construction of a new line at its Marshall, Mississippi, insulation plant. When commissioned in 2027, the line will produce wallboard with WR-Tech enhanced water repellence and CR-Tech corrosion resistance. Dow Jones Institutional News has reported that the line is intended to meet increased demand for industrial insulation in the Gulf of Mexico region.

Rockwool CEO Jes Munk Hansen said "North America – and the US specifically – is an important strategic growth area for us. We have four insulation factories on the continent, with a fifth on the way in Washington state."

UK: Denmark-based Rockwool is reportedly in ‘advanced talks’ to acquire a 9.3 hectare site in Sutton Coldfield, West Midlands from Birmingham City Council. The site comprises Zone B of the Peddimore industrial estate, which is approved for light industrial production. Estates Gazette Interactive News has reported that the purchase advances Rockwool's on-going strategic expansion of its presence in the UK.

UK: Denmark-based Rockwool has acquired external thermal insulation composite systems producer Wetherby Building Systems. Reuters has reported that the newly acquired company will now operate as part of Rockwool Wall Systems, under the name Wetherby Wall Systems. The integration parallels that of previous Rockwool acquisitions in other markets, like Fast Wall Systems in Poland and Heck Wall Systems in Germany.

Rockwool CEO Jes Munk Hansen said “The share of stone wool insulation in the Wetherby business has been growing steadily, and we will be completing this transition to a fully stone wool-based portfolio, as we have done in other markets in the past.” He added that this will advance Rockwool’s transformation of the construction sector towards non-combustible façades.

Wetherby Building Systems managing director Bob Deane said “There is a long-standing relationship between Wetherby and Rockwool, and the match is strong on all significant drivers.”

India: Rockwool India has commenced construction of a new US$65.5m mineral wool insulation plant in Cheyyar, Tamil Nadu. The Hindu newspaper has reported that the plant will produce 50,000t/yr of stone wool insulation from its commissioning in early 2026. The plant will employ 150 people and will overtake the Dahej, Gujarat, plant as Rockwool India’s largest. The subsidiary of Denmark-based Rockwool opened the 40,000t/yr Dahej plant in 2011.

Managing director Darryl Mathews said “Our non-combustible products are witnessing increasing demand in India. Additionally, we will introduce dual-density technology aimed at residential renovation and construction projects.”

Group chair Thomas Kähler said “I am pleased to announce our second investment in India. This expansion is just the beginning, as we anticipate further developments in response to the growing demand for our products.”

Sweden: Rockwool says that it plans to build a new 100,000t/yr stone wool insulation plant in Eskilstuna, Södermanland. When commissioned after June 2027, the plant will serve the Swedish and Finnish markets. It will run on low-carbon electricity from Sweden’s national grid.

Nordics regional managing director Frank Larsen said "Our customers are increasingly demanding low-carbon footprint building materials to achieve their own decarbonisation objectives as well as EU-wide targets in the Energy Efficiency and Energy Performance of Buildings directives. Rockwool's proprietary large-scale electrical melting technology, drawing on Sweden's abundant supply of low-carbon electricity, will help meet this need, which we expect to grow over time as the EU directives get implemented."

Denmark: Rockwool’s net sales grew by 6% year-on-year to €918m in the first quarter of 2024 from €866m in the same period in 2023. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 32% to €216m from €164m. It attributed the growth in sales on higher volumes, but it noted that its product mix had adversely affected sales. The group’s insulation segment did particular well due to higher sales volumes in Eastern Europe, North America and South Asia.

CEO Jens Birgersson said “Prices have remained broadly stable during the quarter, with demand remaining solid in North America and parts of Asia. The Insulation segment performed well overall on sales and earnings, whereas performance was more challenged in the Systems segment. I am pleased that we successfully started up our new green energy technology in Switzerland – the biggest stone wool electric melter in the world.”

US: Rockwool North America plans to build a new US$175m stone wool insulation plant at Wallula Gap, Washington. The Denmark-based producer has acquired 101 hectares of land at the Port of Walla Walla, local press has reported. The upcoming plant will produce insulation using Washington’s abundant igneous rock.

Rockwool North America already operates two other US plants, at Byhalia in Mississippi and Ranson in West Virginia, alongside a further two in Canada. It employs 1100 people, and this will rise by 11% to over 1200 people following the entry into operation of the Wallula Gap plant.

Ukraine: The National Agency on Corruption Prevention (NACP) has added Denmark-based Rockwool to its list of “international sponsors of war” due to the company’s continued business in Russia. The government agency alleges that Rockwool has continued to supply its construction material products to various state institutions in Russia, including the Ministry of Defence, following the start of the Russia-Ukraine war in early 2022. The NACP highlighted that Rockwool operates four subsidiaries in Russia and it suggested that deliveries under state contracts were made via intermediaries in 2023.

In February 2023, The Danish Business Authority announced an investigation into Rockwool's alleged supply of its products to the Russian military, in breach of existing sanctions, between 2015 and 2020. In April 2023 Rockwool chair Thomas Kähler told the company’s annual general meeting that continuing to do business in Russia was the group’s ‘least bad option.’
