As Massachusetts investigates the causes of three house fires that ignited while insulation contractors were installing spray polyurethane foam (SPF), observers ask if SPF is being demonized.
As an insulation product, spray polyurethane foam (SPF) has many great attributes that we’ve talked about on this website: easy installation in irregular locations, air barrier qualities, and moisture management potential. Our publications and blog have also been active in covering some of the downsides of this product, including toxic emissions for workers and occupants under investigation by the EPA and the high global-warming potential of SPF. We have also been publishing a series of reflections by a builder who strongly favors more natural, breathable materials like cellulose.
