Spray-polyurethane foam (SPF) insulation, growing in popularity, is under scrutiny from EPA.
This is a situation we face with some regularity in green building. We are racing to make our buildings safer, healthier for occupants, less-polluting, and lower carbon. But we are behind in that race. Although we have been paying serious attention to the health effects of building materials on indoor air quality for about 20 years, we have been inventing new chemicals that affect our indoor air quality for well over 100 years.
So, the issue of the day? SPF safety. Some products, such as adhesives,coatings, and spray foam, react while being applied by builders or homeowners doing insulation retrofits, and continue to react for some hours afterwards, and may contain "uncured" isocyanates to which people may be exposed.
So the real question is, is the problem here with SPFs or with untrained DIYers?
