Insulation industry news from Global Insulation

US: The Reflective Insulation Manufacturers Association International (RIMA International) has elected three new members to its 2025 board of directors. Rodney Miller of Florida-based Fi-Foil, Philip Ramstack of Iowa-based MWI Components and Paul McIlwee of Pennsylvania-based Environmentally Safe Products will sit on the board for the rest of 2025.

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.

US: The Polyisocyanurate Insulation Manufacturers Association (PIMA) has opposed the Washington State government’s identification of all organohalogen flame retardants (OFRs) as a priority chemical for additional regulations, including a possible ban. PIMA, along with other industry associations, argues that a blanket treatment of OFRs ignores variations in their chemical structure and risk profiles, thereby complicating efforts to identify safer alternatives while continuing to ensure insulation’s performance and fire safety.

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."

US: The Center for the Polyurethanes Industry (CPI) has awarded construction, automotive and packaging products company Woodbridge the 2024 Polyurethane Innovation Award. The award acknowledges Woodbridge’s advancement of life-enhancing products and initiatives over the two-year period of June 2022 – June 2024.

Woodbridge vice president, advanced products and chemical technology, Mike Irwin said "We are pleased that Woodbridge has been honoured with the prestigious CPI Award. Our scientists have developed a proprietary process to seamlessly integrate biogenic carbon into our polyurethane foam. The result is TrimVisible BIO, a novel product that reduces CO₂."

CPI director Jason Sloan "CPI congratulates Woodbridge on this remarkable achievement. Sustainability is at the top of mind for manufacturers and the value chain. Woodbridge's TrimVisible BIO illustrates how polyurethanes are helping drive progress with durable solutions, and CPI is proud to recognise and honour Woodbridge on this cutting-edge innovation."

US: Holcim US has signed a deal to acquire advanced insulation systems producer Ox Engineered Products for US$136m. Switzerland-based Holcim says that the deal is scheduled for completion later in 2024. Ox Engineered Products’ product range includes IsoREDCi polyisocyanurate (PIR) insulation and Ox-IS and Strong-R insulated structural sheathing.

Holcim CEO Miljan Gutovic said "Ox Engineered Products is the ideal addition to Holcim’s business in North America, with its complementary range of proprietary technologies and trusted brands. Its premium solutions enable us to offer the full suite of building envelope systems to our North America customers, from residential to commercial applications. I warmly welcome all 210 employees of Ox Engineered Products to the Holcim family."

US: Carlisle Construction Materials has awarded a contract to Germany-based polymers producer Covestro to supply its 99%-reduced CO₂ bio-circular methylene diphenyl diisocyanate (MDI). Carlisle Construction Materials plans to use the materials in its polyisocyanurate (PIR) insulation boards. Covestro says that it will supply its Mondur CQ 489 product, which will be suitable for use across Carlisle Construction Materials’ Hunter Panels, SynTec, Versico and WeatherBond product ranges. The supplier says that switching to this MDI will save 2.4t of CO₂ emissions per tonne used.

Carlisle Construction Materials president Steve Schwar said "Carlisle Construction Materials has always been at the forefront of developing high-performance construction products that lead the way in sustainability. With our new bio-based rigid foam insulation, we are demonstrating our unwavering commitment to environmental responsibility, while ensuring that our customers have access to the most advanced building materials available. Our partners play a pivotal role in the realisation of our bio-based isolation."

Covestro’s head of performance materials Hermann-Josef Doerholt said "Covestro’s vision to become fully circular requires research and development advancements that directly support the Scope 3 goals of our customers like Carlisle. Covestro has some of the most aggressive sustainability and climate targets in the chemical industry, and the further we progress in developing solutions to achieve them, the more the effects resonate along the supply chain.”

US: Owens Corning’s sales were US$5.09bn in the first half of 2024, up by 4% year-on-year from US$4.89bn in the first half 2023. The company's adjusted earnings before interest, taxation, depreciation and amortisation (EBITDA) for the period was US$1.31bn, up by 14% from US$1.15bn one year previously.

Chair and CEO Brian Chambers said "Owens Corning delivered another outstanding quarter, generating strong margins and cash flow while completing the acquisition of Masonite and continuing our review of glass reinforcements. Through our talented people and highly valued customer partnerships, we continue to outperform the market as we transform and grow into an even stronger residential and commercial building products company for the future."

US: Knauf Insulation has secured US$3.28m in funding from the Environmental Protection Agency (EPA) to develop and verify Environmental Product Declarations (EPDs) for insulation. Knauf Insulation will produce the EPDs based on comprehensive Life Cycle Assessments of its products.

Knauf North America director of sustainability Gabriela Fleury said "Transparency is embedded in our core values and a key component of our business conduct. It is imperative that our product documentation provides accurate, reliable and updated information to our stakeholders. This grant will leverage the development and improvement of EPDs, which not only allows clients to make informed decisions about lower embodied carbon products, but also indicate areas of improvement to lower greenhouse gas emissions throughout our operations. This grant represents a significant sustainability leap for all of our stakeholders. It enables us to enhance our EPD portfolio, meeting increasing market demands for product transparency."

North America: The North American Insulation Manufacturers Association (NAIMA) has reported that its members recycled 1.36Mt of materials in their insulation products in 2023. Recycling Today News has reported that the main fraction used was glass, at 1.18Mt, 87% of the total. 1.15Mt of this (77%) was used in insulation production in the US, and 191,000t (23%) in Canada. NAIMA's industry-wide recycling programme has diverted 47Mt of recycled materials into insulation production since 1992.

NAIMA president and CEO Curt Rich said "Our industry continues to demonstrate its commitment to using recycled materials in the production of these essential products. With increased focus on whole building decarbonisation, insulation products will be a critical component of that activity. Sourcing recycled materials is one way we can decrease our environmental impact while producing essential insulation materials that ultimately lower building emissions."
