Insulation industry news from Global Insulation

Spain: Saint-Gobain has launched a €40m expansion and upgrade to reduce CO₂ emissions by 70% at its Azuqueca insulation plant in Castilla-La Mancha. The producer will replace the plant’s existing furnace with a new electric one. When operational in early 2026, the upgraded line will expand the Azuqueca plant’s capacity by 40%. The furnace will run on renewable electricity sourced under a power purchase agreement signed with utilities provider Endesa in 2022.

North America: Kingspan Insulated Panels North America has released its second annual sustainability report, detailing progress in the third year of the company’s Planet Passionate sustainability initiative. In 2023, Kingspan advanced its use of renewable energy, converting its DeLand, Florida, insulation plant to 100% on-site solar power. The producer reduced its total Scope 1 and 2 CO₂ emissions by 5% year-on-year and its water consumption by 2.17ML compared to 2022. It partnered with Belter Tech to divert 454,000kg of polyisocyanurate (PIR) foam from landfill.

Director of Sustainability Brent Trenga said "Planet Passionate is transforming the business on all levels, recognised by our leadership, employees and the building professionals we collaborate with. We are proud of our 2023 achievements and continue to strive for new milestones in 2024."

Sweden: Rockwool says that it plans to build a new 100,000t/yr stone wool insulation plant in Eskilstuna, Södermanland. When commissioned after June 2027, the plant will serve the Swedish and Finnish markets. It will run on low-carbon electricity from Sweden’s national grid.

Nordics regional managing director Frank Larsen said "Our customers are increasingly demanding low-carbon footprint building materials to achieve their own decarbonisation objectives as well as EU-wide targets in the Energy Efficiency and Energy Performance of Buildings directives. Rockwool's proprietary large-scale electrical melting technology, drawing on Sweden's abundant supply of low-carbon electricity, will help meet this need, which we expect to grow over time as the EU directives get implemented."

Italy: Saint-Gobain has entered into a 10-year power purchase agreement (PPA) with Switzerland-based utilities provider Axpo Holding. Under the agreement, Axpo Holding will supply 22GWh/yr of renewable electricity from a newly built wind farm in Puglia. The deal will fulfil 11% of Saint-Gobain's Italian energy needs across 10 sites.

The latest PPA with Axpo Italia is Saint-Gobain's fifth in Italy. Collectively, these will bring the group’s reliance on renewables in its Italian operations to 20%.

North America: Saint-Gobain has signed a 100MW solar power purchase agreement (PPA), called Danish Fields, with TotalEnergies. The Danish Fields PPA will supply Saint-Gobain North America with solar energy for 15 years, commencing in 2024. Saint-Gobain says that it expects the PPA to eliminate 90,000t/yr of CO₂ emissions across its operations. This is the group’s third deal of its kind.

Saint-Gobain North America CEO Mark Rayfield said “With this agreement, Saint-Gobain North America will further reduce its CO₂ emissions, demonstrating how fast the manufacturing industry can transform when long term solutions are at hand. This renewable energy project is a new milestone on the way to meeting Saint-Gobain’s commitment to reduce Scope 1 and 2 CO₂ emissions by 33% by 2030 compared to 2017, and to reach carbon neutrality by 2050.”

Germany: Grenzebach says that it has completed the construction of the Hütten wood fibre insulation plant in Bavaria's Neustadt an der Waldnaab District for Ziegler Group subsidiary Naturheld. The plant took a total of 12 months to build, and will run on 100% renewable energy. Naturheld will use waste wood from Ziegler Group's wood processing operations in the region. Grenzebach says that it developed a novel wood blending system for implementation at the plant. The supplier said that the plant has a wood fibre production capacity of 6t/hr, and is capable of expanding to 10t/hr. The plant gives Ziegler Group the capacity to produce 1.5Mm²/yr of its wood fibre insulation product.

Managing director Stefan Ziegler said "Building the wood fiber insulation board plant within such an extremely short period was possible only thanks to the close cooperation with a renowned automation partner of international standing like Grenzebach. As a solution provider, Grenzebach supplied both the necessary product and technical know-how and expertise and was able to make the required capacities available at all times."

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."

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.”

UK: Denmark-based Rockwool has announced plans to replace natural gas used in its Bridgend stone wool insulation plant's combustion systems and curing ovens with green hydrogen produced on-site. Engineering company Marubeni Europower and consultancy Mott MacDonald will also be involved in the project. H2 News has reported that the work will rely on US$462,000 in government funding.

Rockwool's managing director Rafael Rodriguez said “The group has set ambitious decarbonisation targets, verified and approved by the Science Based Target Initiative, and in line with this, we are looking forward to enhancing our own understanding about the potential for green hydrogen use in our business.”

US: In 2019 Owens Corning sourced 1.58GWh of energy renewably (49% of total consumption), down by 14% year-on-year from 1.84GWh (52% of consumption) in 2018. Direct CO₂ emissions were 2.78Mt, down by 2.0% from 2.83Mt in 2018 due a reduction in carbon intensity of insulation production, such as the use of electric rather than coke-fired furnaces.
