Basement spray polyurethane foam applications are one of the main and most preferred application details. The unheated basement & garage ceiling also uses the advantage of the spray polyurethane to have no joints and makes a monolithic application and does not allow the formation of thermal bridges at the column-beam junctions. Spray polyurethane can be left after the application on the ceiling details that are not exposed to the sun, or it can be covered with gypsum plaster or painted directly in the desired color.
