Sustainable Insulation Materials

Detailed overview of innovation with sample startups and prominent university research


What it is

Sustainable insulation materials are a new breed of insulation products designed to minimize environmental impact while providing excellent thermal performance. These materials are typically sourced from renewable resources, utilize recycled content, or are manufactured with lower embodied energy compared to traditional insulation options.

Impact on climate action

The development of Sustainable Insulation Materials under Low-Carbon Construction Materials significantly reduces carbon emissions in the building sector. By enhancing energy efficiency and minimizing environmental impact, it advances climate action by curbing greenhouse gas emissions and promoting sustainable building practices, crucial for combating climate change.
