ORNL Robotic Spray Foam System: 50% Labor Reduction, Now Available for Licensing
#1Oak Ridge National Laboratory's robotic spray foam system — developed under DOE's Building Technologies Office — has cleared the critical threshold from research prototype to commercial licensing. It was publicly demonstrated at HUD's Innovation in Housing Showcase in June 2024, with ORNL actively seeking manufacturing and commercialization partners to bring it to market. The system uses a robotic arm with cavity-sensing vision guidance to apply closed-cell foam at controlled rates, achieving 10% better material yield (by eliminating the human tendency to over-apply) and documented 50% reduction in labor hours for wall cavity application in new residential construction.
