Insulation industry news from Global Insulation

Germany: The Central German Architects' Day took place in Apolda, Thuringia, in October 2024. The event included in-depth discussions on possible uses of regionally available alternative raw materials in insulation production. Stern Online News has reported that avenues for exploration include a novel load-bearing straw-based insulation developed at the Bauhaus University Weimar in Thuringia.

UAE: A researcher team at the United Arab Emirates University (UAEU) has developed a novel bio-polyester insulation based on polyhydroxybutyrate derived from date pits. The material has a thermal conductivity of below 0.1W/mK, with 80MPa compressive strength and 6 – 14MPa tensile strength. EurekAlert News has reported that the materials is also below 6% water absorbant.

Team leaders Amal Mlhem and Thomas Teklebrhan said that the bio-polyester insulation can lower the CO₂ emissions of commercial insulation and offer a biodegradable alternative.

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."

UK: A team at the University of Exeter in Devon is investigating possible types of insulation for small-scale farms to produce using byproducts from crop harvests. The project, supported by construction engineering firm Local Works Studio, is part of the Ecological Citizens Network. It is intended to bolster rural economies, address industrial labour shortages and advance sustainable construction. Farmers Guide News has reported that an accompanying podcast and other publications will help to generate engagement.

Team leader Caroline Nye said "Participation and employment in a pioneering, environmentally sensitive new industry, centred in the countryside, could foster a closer engagement of deprived rural communities with the land and bring the benefits of a distributed local economy."

Germany: Bauder has launched BauderECO FF, an 80% biomass polyisocyanurate (PIR) insulation for flat roofs. Construction Management News has reported that the product offers 75% reduced CO₂ compared with conventional PIR insulation, and is compatible with the Bauder Total Roof System and Thermofol warm roof waterproofing products.

Germany: Researchers at the Fraunhofer Institute for Applied Polymer Research have developed a novel insulation from fungal mycelium. Professional Engineering News has reported that the materials are naturally woven by the mycelium filaments by which fungi spread. Researchers successfully varied fungus type, feed and environmental conditions to produce a range of performance characteristics comparable to conventional expanded polystyrene (EPS) and extruded polystyrene (XPS) insulation. Additionally, the materials offer high fire resistance and moisture regulation.

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.”

Finland: Stora Enso has launched NeoLigno, a bio-based binder for mineral and glass wool insulation, designed to replace formaldehyde and isocyanates. NeoLigno is produced from lignin, a byproduct from the pulp industry. Stora Enso says that it offers superior mechanical strength and performs better in humid conditions than classic binders.

Senior research and development specialist Sara Faldt said "We see no major modifications or redesigns needed in the production line for companies who wish to make the sustainable switch and implement NeoLigno."

Australia: Murray Industrial Hemp has announced plans for an upcoming hemp-based building materials plant in Barham, New South Wales. Its products will include alternative insulation panels. Local press has reported that all of the plant’s products will align with Australia's new 7-Star Building Standards for energy-efficient homes. Murray Industrial Hemp expects to commission the plant by early 2026.

Director Joe D'Alo said "We believe industrial hemp holds the key to transforming how Australia builds. Our goal is to assist mainstream builders, enabling them to seamlessly integrate hemp building products into their standard processes. The building process doesn’t change with hemp blocks and hemp panels."

France: Saint-Gobain subsidiary Isonat is investing Euro10m in a capacity expansion to its Mably insulation wood fibre insulating panels plant. French Collection News has reported that the expansion will double the plant’s capacity to 42,000t/yr. The company says that it aims to double its sales in two years. It noted growing demand for bio-sourced materials and the availability of favourable home renovations subsidies.
