Carlisle Construction Materials Introduces Revolutionary Bio-Based Polyiso Eco Rigid Foam Insulation

Key Highlights of Carlisle’s Polyiso Eco:

• Sustainable Composition: The new rigid foam insulation comprises 5% bio-circular content derived from renewable raw materials. This innovative approach not only contributes to reducing reliance on fossil resources but also plays a crucial role in minimizing the carbon footprint of construction projects.
• Strategic Partnerships: By partnering with Covestro for MDI (methylene diphenyl diisocyanate) and Stepan for polyol components, Carlisle Construction Materials ensures that its bio-based Polyiso Eco is manufactured with the highest quality ingredients, designed to deliver superior thermal performance and longevity.
• Enhanced Performance: Carlisle’s Polyiso Eco maintains the same high standards of durability, thermal efficiency, and compressive strength that customers have come to expect from traditional ISO products.
• Industry-Leading Innovation: This pioneering move toward incorporating bio-circular content signifies Carlisle Construction Materials’ dedication to innovation and its proactive approach to integrating more sustainable practices within the construction industry.

“Carlisle Construction Materials has always been at the forefront of developing high-performance construction products that lead the way in sustainability,” said Steve Schwar, President of Carlisle Construction Materials. “With our new Polyiso Eco insulation, we are demonstrating our unwavering commitment to environmental responsibility while ensuring that our customers have access to the most advanced building materials available.”

The collaboration between Carlisle Construction Materials, Covestro, and Stepan represents a landmark in the adoption of renewable materials within the construction sector. Covestro, with its expertise in producing high-quality MDI, and Stepan, a leader in innovative polyol products, provide the essential components for creating Carlisle’s cutting-edge insulation.

“Our partners play a pivotal role in the realization of our bio-based ISO,” added Schwar. “Together, we’re not only pushing the boundaries of material science but also supporting the construction industry’s transition to a more sustainable future.”

Carlisle Construction Materials’ Polyiso Eco is ideal for a wide range of applications, providing architects, builders, and developers with an energy efficient solution that offers bio-based content.

“Covestro’s vision to become fully circular requires R&D advancements that directly support the scope 3 goals of our customers, like Carlisle” said Hermann Doerholt, Head of Performance Materials at Covestro. “Covestro has some of the most aggressive sustainability and climate targets in the chemical industry, and the further we progress in developing technologies to achieve them, the more the effects resonate along the supply chain.”

“Stepan is fully committed to its sustainability priorities of People, Planet, Products, and Practices,” said Scott Behrens, President and Chief Executive Officer of Stepan. “Delivering bio-based products is a critical piece of that commitment. We are thrilled to work alongside our industry partners such as Carlisle Construction Materials and Covestro to bring these important innovations to the market and end consumer.”
