Abstract
The specification discloses a fire resistant foam insulated building panel comprised of two skins having a cellular plastic core between them and a fire resistant coating on the interior face of at least one skin. The fire resistant coating is comprised of a film-forming organic polymer having solid, reactive ingredients distributed therethrough which will react when exposed to heat to release nonflammable gases. The gases are entrapped in the film causing it to expand into an insulating barrier up to one hundred times thicker than the original coating.
