Insulation industry news from Global Insulation

UK: The Peatland Progress bog restoration project in Cambridgeshire will plant and harvest bulrushes for use as a raw material in alternative insulation production. The Evening Standard newspaper has reported that trials have successfully produced insulation from bulrushes in Germany and the Netherlands. Peatland Progress holds Euro9.08m in National Lottery funding. The project will rewet peat and restore wetland habitats over 120 hectares of the historic Fens.

Europe: Dow has announced the European launch of V PLUS Perform Next, a polyurethane (PU) insulation product for use in insulated metal panels. V PLUS Perform Next insulation contains alternative raw materials from circular feedstocks, including bio-based feedstocks. Dow allocates the feedstocks based on a mass balance chain of custody, validated by International Sustainability and Carbon Certification (ISCC). It produces V PLUS Perform Next using over 25% renewable energy.

Dow PU construction insulation marketing fellow Alberto Mercati said “The new EU Energy Performance of Buildings directive adds urgency for buildings that require energy efficient insulation with decreased embodied carbon. For the last five years, V PLUS Perform has enabled insulated metal panel manufacturers to deliver building envelopes that couple energy efficiency and fire safety. V PLUS Perform Next supports insulated panel manufacturers to select lower carbon and circular construction ingredients from the design phase to the delivery of a novel class of products for more sustainable buildings.”

Germany: Knauf Insulation has launched new overwraps on its global insulation product portfolio. The new packaging reduces ink consumption by 70% through its design, featuring a white or off-white base hue and no more than one additional colour. The wraps are designed to maximise ease and efficiency and reduce cost of recycling. This is in line with Knauf Insulation's commitment to recycle over 25% of packaging by 2025. Within the same timeframe, it also aims to reduce its packaging's virgin plastic consumption by 25% and collect over 35% of delivery pallets for repair and reuse or recycling.

Germany: Ireland-based Kingspan has concluded a deal to acquire mineral wool-based sandwich panels producer Calostat from speciality chemicals company Evonik. Calostat's boards have Cradle to Cradle Gold certification for sustainability and employ a unique moisture management concept.

Kingspan said that the acquisition complements its portfolio and enhances its ability to offer the right type of insulation for every application.

France: Saint-Gobain subsidiary Isover has begun construction of a prototype glass wool recycling plant in Chemillé-en-Anjou. Contractor Eiffage Génie Civil is executing the project, which is scheduled for commissioning in 2023.

Isover France and Switzerland technical director Jérôme Saulnier saud "The realisation of this revolutionary industrial prototype with fusion by immersed burners will make it possible to recycle glass wool in industrial quantities, transforming it into cullet. This cullet will be used in the manufacturing process of our insulating products and will also reduce our energy consumption, our carbon emissions and improve the life cycle of our products."

Kazakhstan: KazFeltec and Italy-based Cormatex plan to build a Euro10m natural wool insulation plant in Aktobe Region. Kazakhstan General Newsline has reported that the plant will use local coarse sheep’s wool, a waste product of which 3500t/yr is generated currently in Aktobe. The plant is scheduled for commissioning in mid-late 2023.

US: Knauf Insulation is celebrating the 20th anniversary of the beginning of operations at its Shasta Lake glass wool insulation plant in California. Local press has reported that the company increased its capacity by 70% over the past two decades. Today, the Shasta Lake plant employs 156 people. It has implemented sustainable practices in its production, including the use of ECOSE Technology plant-based binders in the place of petrochemical alternatives. It also recycles 600,000 glass bottles daily, constituting 50% of its glass consumption. This presented the plant with difficulties when Covid-19 lockdowns reduced local waste glass generation.

US: Owens Corning’s 16th Sustainability Report has detailed the producer’s progress towards achieving its 2030 sustainability goals. The report covers indicators under 16 topics to demonstrate its environnmental footprint reduction. These included lowering greenhouse gas emissions, increasing recycled content and circularity, improving energy and process efficiency, increasing renewable energy use and fuel switching from on-site fossil fuel use to lower or zero-carbon alternatives. Between 2007 and 2021, Owens Corning reduced its CO₂ emissions by 60%. In 2021, it recycled 635,000t of glass in its glass wool insulation production.

CEO Brian Chambers and senior vice president and chief sustainability officer (CSO) Frank O'Brien-Bernini said "We have established roadmaps to help our teams understand what’s needed to meet our environmental footprint reduction goals. These roadmaps guide our short, mid and long-term strategies, and help ensure that sustainability remains our priority as we innovate to serve our customers, while addressing both the challenges and the opportunities within the relevant secular trends." They continued "Beyond environmental footprint reduction 'within' our plants, we are working to refine our understanding and set measurable goals for our impact on biodiversity and the circular economy, as well as continually seeking better ways to measure our progress on social impact priorities like inclusion and diversity.”

Germany: BASF has launched Neopor Mcycled expandable polystyrene (EPS) granulate, an EPS insulation raw material containing 10% recycled EPS waste. Building materials producer Karl Bachl collaborated in the product’s development.

Karl Bachl Managing Director Michael Küblbeck said “Today’s EPS insulation materials from the construction and packaging sectors can be fully recycled. At present, the high-quality recycled material is mainly sourced from waste streams from the packaging sector. That means we can already ensure that the recycled material is of the necessary high quality.”

France/Denmark: Ireland-based Kingspan has signed deals for two diversifying acquisitions. On 18 February 2022, it agreed to buy France-based roofing and building waterproofing company Ondura from France-based Naxicap Partners for Euro550m. Meanwhile, in Denmark, the group has also agreed to acquire wood-based acoustic board producer Troldtekt. Troldtekt produces its boards from ordinary Portland cement (OPC) and shredded Norway spruce wood.

Speaking of the latter deal, Kingspan Insulation managing director Alan Lawlor said "I am delighted to welcome Troldtekt to the Kingspan family. As the global leader in high-performance insulation and building envelope solutions, we have the capacity to help them expand beyond their core markets, whilst bringing acoustic and decorative boards and natural insulation materials into our portfolio. Troldtekt has been able to continuously innovate and it sets the bar impressively high in the field of the circular economy.” He concluded "We will invest significantly in the company's production facilities to set them up for geographic growth."
