Insulation industry news from Global Insulation

US: Owens Corning has published its 2022 Sustainability Report, detailing its progress towards its 2030 sustainability goals during 2022. During the year, the insulation producer reduced its CO₂ emissions by 22% compared with 2018 levels, against a 2030 reduction target of 50%. It sourced 56% of its electricity renewably. It achieved this with the help of multiple power purchase agreements (PPA), including for on-site generation. It concluded a new 81.9MW virtual PPA in Spain, which will come online in stages throughout the rest of 2023 and 2024.

Senior vice president and chief sustainability officer David Rabuano said "In 2023 and beyond, sustainability will remain at the heart of our business and a critical value creator for Owens Corning, our customers and other stakeholders. As we shift into the next chapter of our sustainability strategy, we will build on the foundational efforts that have been central to sustainability within our organisation - and with the engagement of our 19,000 employees worldwide, we will take the action needed to reach the next level."

Ireland: Kingspan's CO₂ emissions fell by 26% over the two years between 2020 and 2022. The group aims to achieve a 90% reduction in CO₂ emissions between 2020 and 2030. The Irish Times newspaper has reported that the company adopted a Euro70/t internal pricing mechanism in January 2023. Over the past three years, it increased its renewable energy share to 33% from 20%, increased its rainwater harvesting capacity by 26% and reduced its volume of waste sent to landfill by 42%.

Kingspan head of sustainability Bianca Wong said "It’s a testament to the enduring efforts of our colleagues that we completed over 100 projects in 2022. We will continue to build on our progress to date and aim to further accelerate our strategies in the coming years."

US: Hempitecture has inaugurated a hemp-based insulation plant in Jerome County, Idaho. The plant employs five people and produces insulation using hemp grown in Montana. The producer hopes to supply its flagship HempWool thermal insulation and other acoustic and continuous insulation products to major green building materials markets, including Denver, Los Angeles and San Francisco. It began developing hemp-based insulation in partnership with the University of Idaho with a US$207,000 grant from the Idaho state government in 2021.

Hempitecture CEO Mattie Mead said "We are ushering in the future of truly sustainable building materials."

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.

Belgium: Recticel’s Simfocor polyurethane board product has been certified a ‘Solar Impulse Efficient Solution’ by the Solar Impulse Foundation. The label is awarded to products, services or processes combining credible environmental and economic performance. It also means that Simfocor joins the Solar Impulse Foundation’s list of products selected for their contribution to clean economic growth.

Simfocor is part of the ‘Recticel Silence’ insulation range and is currently sold in France and Spain. It is a polyurethane insulation board that is marketed for both its acoustic and thermal insulation properties. The product is made of recycled polyurethane foams sourced from discarded mattresses.

Ireland/UK: Kingspan has launched a range of reduced-CO₂ insulation panels called QuadCore LEC. The producer says that a 100mm-thick QuadCore AWP panel has 40% lower embodied CO₂ than an EN15804-A2 standard insulation panel of the same thickness.

Kingspan’s head of innovation Mike Stenson said “As a business we are committed to developing high performing, energy efficient building envelope solutions that help minimise the carbon footprint of buildings over the whole life cycle.” He added “QuadCore is already one of the highest performing insulation technologies in terms of thermal efficiency (underpinned by a 25-year thermal warranty), which could enable higher energy and carbon savings through the operational life of the building. This is the first step on our journey to reducing the embodied carbon of our products, and we anticipate some major milestones by 2030 to drive that down even further.”

UK: State-owned Scottish National Investment Bank has granted Euro2.26m in funding to Industrial Nature for the development of its IndiTherm hemp-based insulation. Industrial Nature is based in Edinburgh, Scotland.

Türkiye: The Turkish government has introduced new rules on the minimum thickness of insulation used in urban construction. Buildings in Ankara must be fitted with 9cm-thick insulation, compared to 6cm previously, while those in Istanbul must be fitted with 8cm-thick insulation, compared to 5cm previously. Suar Energy News has reported that this accompanies new government regulations that require all new builds to source at least 5% of their electricity renewably, as part of a drive for Nearly Zero-Energy Buildings (NZEB).

US: Owens Corning has achieved inclusion on the Dow Jones Sustainability World Index 2022, topping the Building Materials category. The producer scored 88 out of 100 for sustainable performance across multiple indices. It recorded full marks for environmental reporting, materiality, recycling strategy, risk and crisis management and social reporting.

Owens Corning's senior vice president and chief sustainability officer David Rabuano said, "Earning placement on this index for the 13th consecutive year is a validation of the daily efforts of our colleagues across our operations globally. I am proud that their hard work and diligence in our sustainability efforts continues to be the driver of our leadership on the Dow Jones Sustainability Index - and an ongoing contributor to achieving our goals for 2030 and beyond."

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.”
