Insulation industry news from Global Insulation

France: Revibat has announced the launch of a new 1.5t/hr glasswool recycling line, featuring recycling equipment supplier Andritz’s NeXline AirLay system. The line, situated near Paris, will receive post-consumer glasswool from around the French capital. Revibat says that it plans to roll out the NeXline AirLay system in order to supply its recycled insulation production operations across France.

Ireland: Ecological Building Systems has launched its new Gramitherm 90% grass and jute-based insulation. Ecological Building Systems uses biogas from grass fermentation to dry the finished product. The insulation, which features a polyester binder, sequesters 1.5kg CO₂/kg, Specification Online News has reported.

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.

Sweden: Owens Corning subsidiary Paroc has applied to expand its Hällekis insulation plant to 115,000t/yr of stone wool production capacity as part of an on-going upgrade. Nordic Daily News has reported that the company is also electrifying the plant and implementing recycled raw materials use. When commissioned, the upgraded plant will process 100,000t/yr of recycled minerals.

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.

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.”

Brazil: A study has successfully enhanced the insulation properties of styrene-butadiene rubber (SBR) composites by incorporating micronised leather shavings. In a report published in the Journal of Materials Research and Technology, Gabriel Deltrejo Ribeiro and his team concluded that the new SBR-leather composite insulation had a thermal conductivity of 0.073W/mK and achieved a temperature attenuation of about 15°C.

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."

Sweden: BEWI has expanded its expanded polystyrene (EPS) recycling capacities through the inauguration of its new Norrköping circularity hub in Östergötland. The hub occupies the site of BEWI’s former Norrköping insulation plant. The company says that it is equipped with an extruder to produce raw materials for the production of EPS for use in its product offering. Meanwhile, the site’s strategic location maximises the efficiency with which recyclable materials are obtained, for example local construction debris and fish boxes.
