Fraunhofer CSE Develops New PIR-based Aerogel Insulation with DOE Funding

A nanoporous aerogel sample synthesized using freeze-drying.

Buildings account for 40% of the energy consumption in the United States. The U.S. Department of Energy’s Building Technologies Office (BTO) announced that it is investing up to $15.8 million in 13 projects that will drive innovation in early-stage research and development for advanced building technologies and systems that will serve as a foundation for future technological developments and reductions in building energy consumption. Among the projects selected for funding is a Fraunhofer CSE project for a better, more affordable PIR-based insulation material for buildings.

Long-term thermal resistance measurements of plastic foams as per ASTM C1303.

In the project, Fraunhofer CSE and partner Virginia Commonwealth University (VCU) will develop a new polyisocyanurate (PIR)-based aerogel insulation that is better, more affordable, and more robust than a conventional PIR foam. The project team will use a new low-capital intensive freeze-drying method to remove pore-filling solvents in the foam. Due to its nanoporous and open-cell structure as well as the lack of a blowing agent, the improved PIR-based aerogel foam will age better than existing PIR foam. The target R-value is R-12 per inch, almost twice as high R-value as a conventional PIR foam.
