Insulation industry news from Global Insulation

US: Saint-Gobain plans to spend US$32m towards to upgrade to CertainTeed’s Chowchilla glasswool plant in California. The investment is part of a US$400m expansion package planned for four US plants previously announced in November 2021. The upgrade work at Chowchilla will include the addition of a new furnace and other equipment that will use less natural gas and electricity. It is the largest investment in the site since its creation in 1978. Saint-Gobain Group estimates that these improvements will reduce CO₂ emissions by 4000t/yr at the site.

Belgium: Knauf Insulation has officially opened a new Euro15m glass mineral wool recycling plant in Visé. It will recycle the glass mineral wool as part of its ‘Resulation’ service. The site will also recycle production off-cuts from Knauf Insulation’s Visé glass mineral wool production plant using a dedicated production line and furnace. The inauguration event was attended by Olivier de Wasseige, managing director of the Walloon Enterprise Network.

Dominique Bossan, member of Knauf Group’s management committee and head of Knauf Insulation Europe, Middle East and Asia, said, “The new facility is an important step towards achieving Knauf Insulation’s commitment to generate zero waste to landfill by 2025 as part of the company’s ‘For A Better World’ sustainability strategy.

Knauf Insulation says that around 85,000t/yr of glass mineral wool waste are generated in France, while in Belgium and the Netherlands the figure is around 30,000t/yr with 26,000t of that total coming from demolition.

Russia: Denmark-based Rockwool has cancelled plans for a Euro200m expansion to its Vyborg stone wool insulation plant in Russia. In a statement, the company said that it would continue its operations in the country, while also respecting international sanctions. Rockwool employs 1200 people in Russia, 10% of its total employees.

In defending its decision to maintain ordinary operations, the producer said “For Rockwool, there is no contradiction in standing side by side with the Ukrainian people and at the same time standing side by side with our Russian colleagues.” It added that it has donated to the Danish Red Cross to support Ukrainian victims of the Russian invasion of Ukraine.

France: Isover plans to spend Euro120m on increasing the production capacity of its existing production lines and building a new line by 2025. The subsidiary of Saint-Gobain says the move will add over 70,000t/yr to its glass wool production capacity. The move is in response to “very strong demand driven by energy renovation.”

Euro20m of the planned investment will be targeted at decarbonising production and developing the circular economy. Isover intends to install a treatment unit for deconstruction waste to be reincorporated into the production process as a substitute for virgin raw materials. It also wants to increase in the proportion of recycled glass used in the production process to 80% by 2025.

Isover operates three glass wool plants in France, at Chalonsur-Saône, Chemillé and Orange respectively.

US: CertainTeed plans to invest US$32m in a capacity-expanding upgrade to its Chowchilla, California, glass wool insulation plant. The producer will install a new furnace, kiln and oxygen generation unit at the facility. It says that the upgrade will increase the plant’s capacity by 13% and reduce its carbon footprint by 4000t/yr.

Germany: Knauf Insulation plans to increase the production capacity of its Bernburg, Saxony-Anhalt, glasswool insulation plant. The project will also modernise all of the plant’s equipment. The upgraded plant is scheduled for commissioning in 2023.

Central Europe regional managing director Michael Huesmann said "The market hunger for insulating materials necessitates the use all production resources as efficiently as possible. Operational safety has gained additional importance as we maximise capacity utilisation – a process which will likely continue in the future."

Russia: TechnoNicol plans to invest around Euro350m towards building two stone wool plants as well as other expanded production in other business areas including agricultural applications. A 1.5Mm³/yr stone wool plant will be built in the Novgorod special economic zone, according to the AK&M Information Agency. Construction of a new 1.4Mm³/yr stone wool plant near Almaty in Kazakhstan is scheduled to start in the first quarter of 2022. Both project have a combined an investment of Euro127m. Additionally, the insulation producer is reportedly looking for a site to build an additional stone wool plant in the far east of Russia.

The company also plans in 2022 to launch a new production line for stone wool substrates for use in greenhouse farming at a plant in the Rostov region. Around Euro6m will be spent on the upgrade. Once complete the line will be able to supply the Southern Federal and South Caucasus districts. It will be TechnoNicol’s third production line for mineral wool substrates, joining plants at Ryazan and Tatarstan.

Romania: Belgium-based Knauf Insulation has agreed to acquire the Târnăveni glass wool plant from Gecsat for an undisclosed sum.

Dominique Bossan, the group chief executive officer of Knauf Insulation, said “The Romanian acquisition will support Knauf Insulation’s growth ambitions and add extra capacity to meet increasing demand for our solutions across the Eastern European and Commonwealth of Independent States (CIS) regions.” He added that the company plans to upgrade the plant after the acquisition has been completed.

Slovakia: Knauf Insulation’s plant at Nová Bana produced 104,000t of mineral wool in 2021. Plant director Marián Tkáč told the News Agency of the Slovak Republic (TASR) that the unit reached this record volume despite Covid-19 restrictions, rising input costs and maintenance on the production lines. The plant also installed a flue-gas desulfurisation unit as part of an environmental upgrade in 2021. Despite the high production volume in 2021, Tkáč said that demand for insulation remained high and delivery times were growing.

Russia: TechnoNicol plans to carry out an upgrade at its Khabarovsk basalt mineral wool insulation plant. The planned project will fully automate production at the plant and double its capacity. The producer expects the upgrade to improve safety, sustainability and product quality.
