This type of construction forms a true thermal barrier between front and back of door. 20 gauge steel backer plates are toggle locked to the inside of the back skin prior to assembly. Exterior skins are secured to a (EPS) polystyrene core with Urethane adhesive, a method of construction that is unparalleled in strength.
