Abstract
When sprayed polyurethane foams are fabricated under field conditions, they usually form a continuous layer that controls the flow of heat, air and moisture through the building component they cover. However, the replacement of blowing agents such as chlorofluorocarbons (CFCs) with partially halogenated hydrochlorofluorocarbons (HCFCs), which have thermal insulating performance inherently lower than that of CFCs, has raised the question of the long-term thermal performance of such foams.
