Insulation industry news from Global Insulation

UK: Knauf Insulation plans to build a €202m, 100,000t/yr stone wool insulation plant in Shotton, Flintshire. The new Shotton plant will produce reduced-CO₂ insulation using a submerged arc furnace (SAF). It will be Knauf Insulation’s second in North Wales, along with its existing Queensferry stone wool insulation plant, also in Flintshire. The company’s other UK plants are in Cwmbrân, Gwent, and St Helens, Merseyside.

Managing director of Knauf Insulation Northern Europe Neil Hargreaves said "This project aligns with the Welsh and UK governments’ commitments to sustainability and the industrial vision for North Wales and Deeside. Using UK-first SAF technology, the new factory will support the need for safer, more energy efficient and sustainable buildings."

The new Shotton plant accords with the UK government’s €190m plans for a Flintshire and Wrexham Investment Zone, centred on ‘advanced manufacturing’ and intended to attract €1.19bn of private investments.

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.

Russia: TechnoNICOL plans to build a further plant in Khabarovsk Krai. Interfax Russia & CIS Business News has reported that the plant will produce technical insulation, as well as 80,000m³/yr of shipbuilding insulation and 20,000m³/yr of substrates for vegeculture. TechnoNICOL plans to invest US$3.49m in the plant, and commission it in mid-late 2025.

Russia: TechnoNICOL plans to invest US$11m in automating logistics across its mineral wool plants by 2026. Russian-owned AK&M News has reported that the investments will go towards the installation of automated loading equipment and plant digital twins. This is expected to more than double labour productivity to 180,000m³/yr per worker. Plants scheduled for automation upgrades in 2025 include the Serpukhov and Chudov glasswool insulation plants.

TechnoNICOL’s total investments in automation and digitisation totalled US$2.75m in 2024.

Russia: TechnoNICOL and the Corporation for the Development of the Far East and the Arctic (KRDV) have agreed to build a new US$29.3m, 400,000m³/yr stone wool insulation plant in Khabarovsk Krai. When commissioned in late 2026 or early 2027, the plant will be TechnoNICOL’s third in the krai and will employ 140 people. Russian-owned AK&M News has reported that surveys and design documentation for the plant are scheduled for submission in June 2025.

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."

Russia: TechnoNICOL has installed a new glass furnace and polymerisation chamber at its Serpukhov glass wool plant in Moscow Oblast. AK&M News has reported that that the upgrade will expand the plant’s glass wool capacity to just under 2Mm³/yr and enable it to produce a total of 300 different types of insulation. TechnoNICOL is investing US$18m in the project, which uses equipment from Russian suppliers and is intended to reduce the sanctioned nation’s reliance on imports.

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.

India: Saint-Gobain India plans to double its production capacities of glass and stone wool insulation as part of a new investment phase, targeting revenues of US$4.3bn across its businesses by 2032. The Hindu newspaper has reported that this represents growth by a factor of three from 2023 levels. Saint-Gobain India noted the presence of ‘medium-sized companies in the insulation space’ as suitable targets for acquisitions. The investment phase will include total capex of US$719 – 959m from 2021 to 2025. The company had invested US$1.58bn up to the end of 2023.

Asia-Pacific and India regional CEO B Santhanam said "We have made huge investments in India, and quite a lot of them were in new plants."
