ABSTRACT:
A modular anti-warping door panel for use in the construction of a door or door panels. The door panel comprises a rigid reinforcing frame constructed of material resistant to warping. The reinforcing frame is defined by two spaced apart elongated rigid members and one or more transverse spaced members. The reinforcing frame is retained in an elongated butte stile and a lock stile and a top and bottom rail. The stiles and rails are formed as hollow members of rectangular cross-section forming a peripheral panel frame. The two elongated rigid members are retained along an inner peripheral channel of the rectangular door frame. Panels are retained in an opening defined by the inner peripheral channel. A rigid post is secured in the butte and lock stiles along an outer edge portion thereof and concealed within the hollow stiles. A connecting element is disposed along an outer edge of the top and bottom rails and interconnected at opposed ends thereof with a top portion of the rigid post of the butte and lock stiles. The two elongated rigid members are received captive at opposed free ends thereof in the connecting element. An insulating rigid core material is disposed in inner spaces of the hollow stiles and rails.
