In the latest episode of the R-Value podcast, IDI's Ken Allison welcomes special guests Rick Duncan, Executive Director of the Spray Polyurethane Foam Alliance (SPFA) and John Stahl of the Metal Buildings Initiative to discuss and dispel the myths surrounding the use of spray foam insulation in metal buildings. The conversation focuses on debunking common misconceptions and providing factual information based on research and industry experiences. Duncan and Stahl have put together a task force to conduct studies and share information with contractors about the safe use of spray foam in metal building applications. They share their extensive background in the field, share insights on the compatibility of spray foam with various types of metal buildings, the effects of spray foam on building elements like paint and structure, and the evolving building codes and standards that impact the use of spray foam in the industry.
