XENERGY™ Extruded Polystyrene (XPS) Insulation boards

DOW technologies

Dow strives to create value through its diversified, market-driven portfolio of specialty chemical, advanced materials, agro sciences and plastics businesses. Leveraging cost advantage, scale and geographic presence – together with close customer collaboration and industry-leading R&D expertise – Dow is delivering differentiated solutions, including XENERGY™, which address current market needs in the Construction segment as well as in other industries. At the intersection of chemistry, biology and physics, Dow’s team of scientists and experts are addressing the world’s most pressing challenges – enhancing the quality of life for current and future generations, all while creating long-term sustainable value for the company, its customers and its shareholders.
Dow is renowned for its ability to respond to market needs and legislative demands through advances made in the technical capabilities of its STYROFOAM™ extruded polystyrene (XPS) insulation. These advances include the launch of a new generation of thermal insulating boards, XENERGY™, which have better insulation performance thanks to the addition of infra-red blocking particles to scatter and reflect heat radiation within the foam board. XENERGY™ sets a new standard for the market. The result is reduced heat transfer during winter to keep a building warm, as well as in summer to keep it cool.

We’re proud of our innovative track record and our proven ability to satisfy ever more demanding building project specifications. In line with this, we continue to listen to customers, and also those who specify our products, to determine where product innovation is required.

We know that there has long been a desire for improved lambda values, that’s to say an improved insulating capacity of a product designed for thermal performance. Customers, such as Architects and investors, want more effective insulation performance that uses reduced thickness of materials and offers greater design possibilities.

Solution description

Research and development at Dow is at the forefront of delivering innovative solutions to some of the world’s toughest challenges, and the company attracts some of the finest researchers from around the world to its state-of-the-art facilities. We rethink what is possible at the molecular level to create breakthrough products and processes that impact the world around us. Researchers collaborate on cutting-edge technology to develop sustainable market-driven scientific and technical innovations.

The development of XENERGY™ is a direct response to the market requirement. The addition of infra-red blocking particles within the extruded cell structure of the product is an innovation in the marketplace worldwide and places Dow Building Solutions on a trajectory to gain better competitive positioning. To achieve this, Dow scientists had to overcome the challenge of incorporating IR-blocking particles into the cellular structure without destroying it. The result of an extensive R&D project was a material which has a perfect close cell structure with the lowest water pick up for an insulating material, improved mechanical properties and most importantly, a significant improvement in thermal insulation.

XENERGY™ products use carbon dioxide as the main blowing agent - the Ozone Depletion Potential (ODP) is zero and the Global Warming Potential (GWP) is less than five. Concern about ozone depletion in the stratosphere has led to international agreements to phase out the use of ozone depleting chemicals. All XENERGY™ products are hydro chlorofluorocarbon (HCFC) free and comply with the requirements of EC Regulation No 2037/2000 (1 October 2000) on substances which deplete the ozone layer.

XENERGY™ is an example of all that Dow strives to achieve. Through understanding the requirements of society and of its own customers, and then investing heavily in research and development, the company is able to bring to market a range of innovative products that satisfy a present need.

Energy efficiency through better insulation is a worldwide issue. While at one level, building regulations are ever more demanding, the needs of consumers in reducing heating or cooling costs are of paramount concern. Through reducing energy usage, XENERGY™ is helping reduce the amount of power that is required to be generated.

Dow’s launch of XENERGY™ insulation is an example of its commitment to research and development and its mission to remain at the forefront of delivering innovative solutions. XENERGY™ is a sustainable market-driven scientific and technical innovation which, as well as keeping homes warmer, will ultimately benefit society through reducing climate change.
