Insulation industry news from Global Insulation

US: Knauf Insulation has secured US$3.28m in funding from the Environmental Protection Agency (EPA) to develop and verify Environmental Product Declarations (EPDs) for insulation. Knauf Insulation will produce the EPDs based on comprehensive Life Cycle Assessments of its products.

Knauf North America director of sustainability Gabriela Fleury said "Transparency is embedded in our core values and a key component of our business conduct. It is imperative that our product documentation provides accurate, reliable and updated information to our stakeholders. This grant will leverage the development and improvement of EPDs, which not only allows clients to make informed decisions about lower embodied carbon products, but also indicate areas of improvement to lower greenhouse gas emissions throughout our operations. This grant represents a significant sustainability leap for all of our stakeholders. It enables us to enhance our EPD portfolio, meeting increasing market demands for product transparency."

Belgium: Etex says that it ‘considerably’ progressed its Road to Sustainability 2030 plan during 2023. That year, safety intensity increased by 7%, and Etex established a global diversity, equity and inclusion ambassador community of 110 volunteers across 26 countries. In Europe, the company achieved 70% Environmental Product Declaration coverage as a percentage of its turnover, up from 58% in 2022. Etex raised its total use of recycled materials to 7.6%, and achieved a 23% reduction in Scopes 1 and 2 CO₂ compared to 2018 levels, in line with its 2030 target of 35%.

CEO Bernard Delvaux said “In the EU, more than 40% of energy consumed is used in buildings and more than 30% of energy-related greenhouse gasses emissions come from buildings. Next to new building activities, and according to current high energy standards, renovating old building stock should hence be a top priority. With our portfolio of building materials such as glass wool and extruded polystyrene insulation, gypsum wallboard, fibre cement boards and fire protection materials, Etex has the solutions to reach the ambitious targets. But in view of the huge challenge, a holistic and effective plan to boost renovation is needed, to finance and simplify the renovation process, in each of the EU countries.”

Germany: Knauf Insulation has compiled its sustainability targets, progress and related information on its products online. The so-called ‘sustainability chapter’ is intended to highlight how Knauf Insulation products can make buildings more sustainable and also charts the company’s progress to reduce its own environmental impact as part of its ‘For A Better World’ initiative.

Jure Šumi, Knauf Insulation’s Group Digital and Brand Manager, said “The new chapter on sustainability is a showcase of valuable information for anyone who wants to create better buildings while taking care of the environment and society.” He added, “It offers valuable insight into how our solutions can lower the environmental impact of buildings with news and case histories in every section highlighting what Knauf Insulation is doing For A Better World.”

The newly organised section on Knauf Insulation’s website lets interested parties download Environmental Product Declarations (EPD) for its products. In addition, the site offers downloadable documents showing how Knauf Insulation products can contribute points to the world’s green building rating systems such as BREEAM, LEED, DGNB and WELL.

The company’s also explains online how it is reducing the environmental impact of its operations in line with its ‘For A Better World’ sustainability strategy. It has set targets for 2025 including sending zero waste to landfill, cutting its accident rate by 55% and reducing the embodied carbon of products by 15%. Knauf Insulation promises regular updates on its progress and initiatives to achieve these targets.

US: Owens Corning has announced a new line of extruded polystyrene (XPS) foam insulation products called Foamular NGX. It is set to go on sale in the US and Canada in January 2021. It says that the proprietary blowing agent in the products deliver a 90% reduction in global warming potential (GWP) without sacrificing product performance. It is Underwriters Laboratory (UL) listed, Factory Mutual (FM) approved and compliant with regulations set to take effect in Canada and some US states in January 2021. The environmental benefits of the products will be reflected in a new Environmental Product Declaration (EPD). The new product line will retain the signature Owens Corning pink colour.

US: DuPont plans to launch new extruded polystyrene foam insulation products in its Styrofoam brand with reduced global warming potential (GWP) from the start of 2021 to meet its 2030 Sustainability Goals and comply with adopted and upcoming state and provincial hydrofluorocarbon (HFC) regulations throughout the US and Canada. The company also expects a reduction in embodied carbon to be reflected in an updated Environmental Product Declaration (EPD), which will be available with the new products.

"We are taking a thoughtful, phased approach to launching this latest Styrofoam innovation to ensure we are providing a sustainable, code-approved solution that does not sacrifice the performance our customers have come to trust," said Tim Lacey, Global Vice President & General Manager, DuPont Performance Building Solution.

Germany: Evonik’s Calostat insulation product has received an environmental product declaration (EPD) from the Institut für Bauen und Umwelt (IBU). The EPD takes into account the entire production process, from manufacture of precursors, their transport, production of Calostat and the option of recycling the material.

Calostat is a non-combustible thermal insulation material based on silicon dioxide.

It is a class A (non-combustible) building material with a thermal conductivity λ of 0.019 W/(mK). It does not absorb liquid water but is permeable to water vapour. Other distinguishing features are its compressive strength of ≥ 90 kPa and gross density of 165kg/m³. It contains no fungicides, algicides, pesticides, binding agents, or flame-retardants. Notably, the manufacturer also says that the product can be recycled.

Brazil/Finland: Saint-Gobain Isover has obtained Environmental Product Declarations (EPD) for its products in Brazil and Finland. It has obtained five EPDs in Brazil where it has become the first insulation company in the country to obtain EPDs registered with Environdec. In Finland it has published three new verified EPDs through the Norwegian EPD platform EPD Norge.

Singapore: Insulation foams producer Armacell has been recognised for its pioneering initiative on environmental certification in the Asia Pacific (APAC) region. The recognition came from UL Environment, which presented Armacell with an Environmental Product Declaration (EPD) Certification during a workshop on Indoor Air Quality and Environmental Product Declarations.

Lisa Meier, UL Environment vice president and global general manager, acknowledged Armacell as the first company to receive EPDs from UL Environment in the Association of Southeast Asian Nations (ASEAN) region. Stephen Hodson, general manager of marketing APAC, said that, "The EPDs are highly important for providing product information to designers of green buildings in Asia."

Armacell's latest EPDs cover seven premium products that are sold across the Asia Pacific region. The initiative, said Armacell's technical manager for APAC Peter Cheng, makes Armacell the first insulation company to receive EPDs from UL Environment in APAC.

Demand for EPDs is growing in response to a change in green building guidelines and design practices. The US Green Building Council's LEED green building programme is now placing emphasis on life cycle assessment (LCA) based environmental reporting and transparency, rewarding points for the use of products with EPDs and LCAs as part of the Material and Resources (MR) Credits. Outside of the US, four of the top ten countries for LEED-certified buildings are in the APAC region: India, China, Korea and Taiwan.

Luxembourg: Armacell is now the first manufacturer of flexible technical insulation materials to present environmental product declarations (EPDs), which are based on an independent life cycle assessment (LCA).

EPDs are becoming more important in the construction industry as they provide a transparent, independent and reproducible analysis of the environmental impacts of construction products and give detailed information with sound data and figures. As a 'sustainability passport,' EPDs form the basis for designing green buildings in accordance with certification schemes such as LEED, BREEAM or DGNB.

Comparing the primary energy input identified in the Armacell LCA with the energy saving achieved shows that using Armaflex insulation materials saves 140 times more energy than is needed for their manufacturing, transport and disposal. The energy input needed to manufacture Armaflex is paid off after just 50 days.

"With the EPDs we create a unique degree of transparency for our Armaflex products. We provide architects, specifiers and those inviting tenders with reliable information for designing sustainable building projects. At the same time we commit ourselves to continuing to improve the environmental friendliness of our products and thus sharpening our competitive edge," said Patrick Mathieu, CEO of the Armacell Group.
