Paul Duffy, the vice president of engineering for Icynene, advises anyone considering the use of spray foam in an existing house to hire a home-performance specialist. “For a retrofit job, we recommend that you have a HERS rater involved, or a BPI-trained professional — someone who understands the house as a system,” said Duffy. “A spray foam contractor doe’t necessarily have all of those understandings on the same level. … It goes beyond the skill set of insulators generally; it goes into the skill set of a building science professional.”
