Spray foam insulation is rated very highly, as being resistant to both smoke and heat. Most of the spray foam insulation used on the market today is rated class one against fire, which is one of the highest ratings a home and business insulation product can receive. While this doesn’t mean it can’t catch on fire or be damaged by heat, it means it isn’t very likely that it would occur. Plus, it also won’t cause heat itself or make something like an electrical overload occur. You can be sure that spray foam companies frequently test their products, to make sure they are safe for use. This makes spray foam insulation a very good choice for consumers.
