Insulation industry news from Global Insulation

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."

Russia: TechnoNICOL says that it will invest US$219m in new mineral wool plants and plant upgrades in Russia throughout 2025, as part of a drive to raise its capacity to 5Mm³/yr by 2030. Interfax has reported that projects include the upcoming Krasnosulinsky stone wool insulation plant in Rostov, scheduled to open in late 2026. In Moscow, the company is investing US$46.2m to rebuild it Serpukhov glass wool plant, scheduled for completion in April 2026. At its Ryazan plant, meanwhile, TechnoNICOL is installing a 1.25Mm³/yr mineral wool recycling line and captive power plant, with a combined investment of US$29m.

Egypt: AlexForm has inaugurated its new US$13.8m, 2.1Mm²/yr Sokhna insulation plant in the Suez Canal Economic Zone. Arab News has reported that the plant is equipped with polyurethane (PU) and stone wool insulation production lines. It will employ 120 workers.

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.

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 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.”

Russia: TechnoNICOL has announced plans for a third stone wool insulation plant in the eastern Krai of Khabarovsk. The plant will have a production capacity of 400,000m³/yr of stone wool, and will produce thermal and acoustic insulation and technical insulation, including stone wool substrates for use in hydroponic plant cultivation. Together with an on-going upgrade to an existing stone wool insulation plant at the site, the project will cost US$37.6m, AK&M News has reported. Pre-design construction, land leasing and procurement of ‘key equipment’ for the new plant are currently underway, with commissioning scheduled for late 2026. TechnoNICOL then expects to complete the upgrade to the existing plant in 2027.

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."

Kazakhstan: Russia-based TechnoNICOL has begun building its upcoming US$124m Karaganda insulation plant. Interfax Kazakhstan Newswire has reported that the plant will export 30% of its insulation to Russia. Additionally, it will export some insulation to China, Kyrgyzstan, Mongolia and Uzbekistan.
