Insulation industry news from Global Insulation

UK: The six-year public inquiry into the Grenfell Tower fire, which claimed 72 lives in 2017, has issued its final report, finding fault with ‘dishonest’ companies, as well as former governments and a disorganised response from the fire service. The inquiry criticised the role of cladding manufacturers, notably US-based Arconic, for its ‘systematic dishonesty’ in concealing the true fire hazards of its products. Arconic, which produced the Reynobond 55 polyethylene cladding used on Grenfell Tower, was accused of having hidden ‘very poor’ fire safety test results from the public and certification bodies. In the report, the cladding is described as ‘extremely dangerous’ when used in folded cassette form, and was ‘by far the largest contributor’ to the Grenfell fire.

The inquiry also named both Celotex and Kingspan as contributors to the incident. Celotex was accused of making ‘false and misleading claims’ by presenting its product to cladding contractor Harley Facades as being safe and suitable for Grenfell, even though ‘it knew that was not the case.’ Insulation producer Kingspan reportedly ‘misled the market’ by not revealing the limitations of its product, which was used on a small section of the building. In response to these findings, the inquiry has called for a revision in testing materials and designs for fire safety, advocating for transparency by making these test results publicly accessible. The findings of this inquiry lay the groundwork for potential criminal charges, with police and prosecutors indicating that investigations will continue until the end of 2025, and decisions on criminal charges expected by the end of 2026, according to a report by the BBC.

Kingspan said in a statement “We welcome the publication of today’s report which is crucial to a public understanding of what went wrong and why. It explains clearly and unambiguously that the type of insulation (whether combustible or non-combustible) was immaterial, and that the principal reason for the fire spread was the PE ACM cladding, which was not made by Kingspan. Kingspan has long acknowledged the wholly unacceptable historical failings that occurred in part of our UK insulation business. These were in no way reflective of how we conduct ourselves as a Group, then or now. While deeply regrettable, they were not found to be causative of the tragedy and Kingspan has already emphatically addressed these issues.”

A spokesperson for Celotex said “The publication of the Grenfell Tower Inquiry report marks the conclusion of the inquiry’s work and we are considering its contents with care. This review was a significant and thorough undertaking, and the results of that work were disclosed promptly and proactively to relevant stakeholders, including the Grenfell Tower Inquiry. Independent testing commissioned following the review demonstrated that the cladding system described in the Celotex RS5000 marketing literature met the relevant safety criteria. That system was substantially different to that used at Grenfell Tower. Decisions about design, construction and the selection of materials for the Tower were made by construction industry professionals.”

A spokesperson for Arconic subsidiary Arconic Architectural Products (AAP), which Building News reports supplied aluminium composite material used for the rainscreen at Grenfell Tower, said “The company respects the Inquiry process. AAP cooperated fully with the work of the Inquiry and will continue to engage with further legal processes. Together with other parties, AAP has made financial contributions to settlements for those affected, as well as to the restorative justice fund. Throughout the Inquiry, AAP has maintained a number of points: AAP sold sheets of aluminium composite material as specified in the design process. This product was safe to use as a building material, and legal to sell in the UK as well as the more than 30 other countries in which AAP customers purchased the product. We reject any claim that AAP sold an unsafe product. AAP regularly conducted tests of its materials using third-party testing bodies. Reports on these results were all publicly available, and AAP made these reports available to its customers. AAP did not conceal information from or mislead any certification body, customer, or the public.”

Belgium: Knauf Insulation has released its ‘Sustainability Journey: 2023 Highlights’ report. It reveals the company’s sustainability strategy achievements focusing on safety, employee engagement, decarbonisation and the circular economy.

The company reduced its absolute full-scope emissions for its mineral wool production by 8.2% year-on-year to 1.34Mt of CO₂e in 2022 from 1.46Mt in 2021, mainly due to a significant fall in Scope 2 emissions. it currently has a target to reduce its specific embodied carbon emissions by 15% from 2021 to 2025. The recycled content of its glass mineral wool products fell to 55% in 2022 from 64%, despite the company having a target of 65% by 2025. It explained that sourcing large volumes of recycled materials of sufficient quality had proved challenging in some markets. However, it did increase the recycled content of its rock mineral wool products to 13% from 11%, with a target of 25% set for 2024. It also reduced its total recordable incident rate by 8% to 5.9 from 6.4 against a target of below 5 for 2025.

Dominique Bossan, the chief executive officer for Europe, Middle East and Asia at Knauf Group, said “The report documents our progress towards achieving our 2025 sustainability targets. It shows the areas where we need to improve, celebrates where we have made positive progress and pays tribute to the hard work of our teams."

Ireland: Kingspan’s consolidated net sales increased by 24% year-on-year in the first quarter of 2021 to Euro1.28bn. Insulated panels sales grew by 25% having started the year with a strong order backlog and insulation boards grew 12%. Communications company Edison Group said that growth was most pronounced in Germany, France and Benelux and Latin America, with a strong order intake in North America and the UK. Net debt at 31 March 2021 was Euro352m.

The company noted increasing inflationary pressure and challenges regarding availability despite strong demand and a strong backlog. As such, it has given no guidance for the year.

Kingspan highlighted its inaugural Planet Passionate sustainability report. The report details the company’s achievements in the first year of its 2019 10-year sustainability strategy. In 2020, the producer achieved net-zero energy and cut CO2 emissions by 5% year-on-year. It issued a Euro750m green private placement in September 2020. The company called the major achievements the ‘first leg’ of its decarbonisation journey. In its latest report, it set the target of net-zero CO2 emissions by 2030. Additionally, it is aiming to halve CO2 intensity over the same period. Altogether, Planet Passionate covers 12 sustainability targets across the key areas of energy, circularity, CO2 and water.

Chief executive officer Gene Murtagh said “Our Planet Passionate targets demand radical thinking and action. Our aim is to get as close to zero emissions in our manufacturing as technically possible by transforming our processes. Industry has a vital role to play in addressing the threat of climate change.” He added that the group target of 50% primary raw materials CO2 intensity reduction “will also lower the embodied carbon in our products, and consequently the whole life carbon of buildings.”

Denmark: Rockwool has detailed its sustainability achievements for 2020 in its Sustainability Reports 2020. During the year, assessment agency S&P Trucost certified all of Rockwool’s products as ‘positively impactful’ in line with the United Nations Sustainable Development Goals (SDGs). The company said that its insulation sold in 2020 saved 874,000GWh of heating energy. It said that the lifetime CO₂ emissions savings of its products are more than 100 times greater than their production emissions. It halved its production waste going to landfill compared to 2019, against reduction targets of 40% by 2022 and 85%. It achieved another of its interim sustainability goals early by increasing water efficiency by 10%, against a targeted 10% by 2022 and 20% by 2030.

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.

US: Johns Manville has released its sixth sustainability report covering 2016 – 2017. The insulation and building materials producer says that it reduced its greenhouse gas emission intensity by 2.5%. It added that it has attained its goal to implement environmental management systems in all of its of North American and European plants three years early and had developed product category Environmental Product Declarations for its heating, ventilation, and air conditioning (HVAC), original equipment manufacturer (OEM) and mechanical insulation materials. It also decreased its lost time incident rate by more than 50% in the reporting period.

US: Johns Manville (JM), the global manufacturer of energy-efficient building products, has announced the publication of its 2012 Sustainability Report, 'We Build Environments.'

"We intend to capitalise on our commitment to sustainability to ensure that we are better prepared to meet both the opportunities and challenges of our dynamic world and that we continue to deliver safe products that delight our customers," said Mary Rhinehart, JM president and CEO. The 2012 report includes 18 fully reported performance indicators applying the Global Reporting Initiative 3.1 guidelines.

Key indicators from JM's 2012 performance summary for the insulation market include a 19% increase of average fibreglass insulation compared to 2011. Total energy use for the company rose by 0.9% and total production fell by 0.4%.

Finland: Paroc Group, a major supplier of insulation to the baltic market, has published its first sustainability report, which covers 2009 to 2011. The indicators presented in the report are tools for measuring and following Paroc's sustainable progress in all its production facilities in Finland, Sweden, Poland and Lithuania.

"Sustainability is a factor which strongly influences the development and renewal of our business because our products play a significant role in improving the energy efficiency of buildings," said Paroc Group's CEO, Kari Lehtinen. "We operate in an energy-intensive industry so the ecological efficiency and waste recyclability provide additional savings while minimising the burden on the environment and thus contributing to our common wellbeing."

Paroc considers its most important goals for the coming years to involve increasing the energy efficiency of its production facilities and reaching the occupational safety target of zero accidents by 2020.

At all of Paroc's production plants, processes operate according to the current regulations and standards. Beatrice Rantanen, Paroc Group's Sustainability Manager, emphasised that its production facilities in Finland and Sweden depend almost solely on green energy and that 75% of Paroc's waste is recycled.

"High-quality heat insulation is the most effective and inexpensive way to affect the energy efficiency of new buildings. The benefits will be emphasised even more when Europe shifts to zero-energy building by the year 2020," added Lehtinen.

Global Insulation recognised Paroc's attention to environmental effects in 2012, awarding the company the Global Insulation Company of the Year award at the Global Insulation Conference & Exhibition in Riga, Latvia in September 2012.

UK: A report has revealed that the UK's insulation market experienced growth in 2010 after declining in 2009. Research and Markets' 'Building Insulation Market - UK 2011-2015' also reveals that insulation is expected to reach an estimated market size of Euro1.16m by 2015.

The report also says that the UK insulation market will continue to be underpinned by the Carbon Emissions Reduction Target, the Green Deal and new building regulations. The largest market sector in 2010 was mineral wool insulation.

The report comes at the same time as figures were released by the Department of Energy and Climate Change, which show that just 57% of Britain's roofs are fitted with proper loft insulation and only 58% of buildings have cavity insulation.

The UK energy and climate change secretary Chris Huhne said, "At a time when money is tight and with energy prices predicted to rise, householders are missing out on over Euro110 of savings every single year by not getting their lofts lagged and cavity walls filled." The government hopes that an additional three million homes will be fitted with insulation by the end of 2012.

US: Owens Corning has released its 5th annual Sustainability Report, outlining the company's environmental footprint reduction performance. "Our 2010 Sustainability Report demonstrates Owens Corning's continued focus on and progress towards improvements in greening our operations and products and accelerating energy efficiency and renewables penetration in the built environment," said Vice President and Chief Sustainability Officer Frank O'Brien-Bernini. "We have met three of our seven goals already and are confident that six of the seven goals will be achieved by 2012."

Among the key accomplishments highlighted in the report is a 24% intensity reduction in greenhouse gas (GHG) emissions compared to 2009 levels. The company removed 950,000t of CO2 from its operations in 2010, which is equivalent to eliminating the CO2 impact of more than 170,000 passenger cars. The report also detailed progress towards intensity reductions in energy usage, and reductions in nitrogen oxides, volatile organic compounds, particulate matter, waste-to-landfill contributions and water usage.

The company took the opportunity to launch a new set of 2020 goals designed to raise the bar on its commitment to sustainability. The announced 2020 goals will target reductions in energy, greenhouse gas, water, toxic air emissions, particulate matter and waste-to-landfill measures, as well as supplier sustainability and life cycle assessments.

"These new goals raise the bar on our commitment to sustainability and reflect an increasingly holistic approach that encompasses how our company operates, the attributes of our products and our desire to affect change by partnering with our customers and suppliers to deliver sustainable solutions," added O'Brien-Bernini.

The disagreement comes at the same time as the publication of an article in the journal Respirology that warns of massive rises in deaths from asbestos-related lung diseases in Asia in the coming decades. Dr Ken Takahashi, Acting Director of the World Health Organisation Collaborating Centre for Occupational Health (WHOCCOH) and his team put together data on asbestos use in 47 Asian countries for the report.

Asian countries accounted for 64% of the global consumption of asbestos in 2001-2007, a striking increase from 14% between 1920 and 1970. This is the result of unregulated asbestos import and use in many Asian countries.
