Spray Polyurethane Foam (SPF) Insulation
A two component mixture comes together at the tip of a gun, and forms an expanding foam that is sprayed onto concrete slabs, into wall cavities of an unfinished wall, against the interior side of sheathing, or through holes drilled in sheathing or drywall into the wall cavity of a finished wall.
Sometimes also called Foamed-In-Place Insulation
