Spray Polyurethane Foam, commonly referred to as Spray Foam, is a spray-applied, insulating, foam plastic that is installed in liquid form and then quickly expands into a permanent, solid, insulating material. As the foam solidifies, it expands at many times its original size. Spray Foam can be easily adjusted based on the requirements for the application, and has many different physical properties and uses. For more information regarding Spray Foam applications visit
