How is foamed-in-place insulation made?
The installer fabricates the foam on-site according to the manufacturer’s instructions. The application equipment and the foam’s chemical components are brought to the home-building site, where framing, electrical, and plumbing are complete, and exterior siding encloses the home. A controlled reaction among the number of mixed chemicals, a blowing agent, and some other additives produces a wet foam mass. Using a specially designed sprayer, the installer sprays or injects the mass unto or between wall surfaces. This mass forms into a hardened cellular plastic material. The exposed surfaces of the rigid foam resemble a hard, tan colored shaving cream.
