About Stress Skins Panels

Stress skins panels normally consist of two exterior “skins” of surfaces surrounding a hard plastic foam core. Comprised of skins usually made of plywood and gypsum board with an expanded polystyrene core that varies in thickness from two to twelve inches and can be up to 8 feet by 24 feet in size, these stress skins are light and easily applied to timber frame homes and yet compare in strength with that of an I-beam.
