Abstract
The present invention is directed to a door facing formed from a polymeric composite material. The door facing has a first major surface intended to be interiorly disposed and a second major surface intended to be exteriorly disposed. At least a portion of the first major surface is to be subjected to thermal and mechanical stresses during door assembly. The first major surface has a textured pattern in the portion to be subjected to thermal and mechanical stresses. The textured pattern includes a plurality of spaced grooves extending into the first major surface and minimizing thermal and mechanical stresses. A door formed with the disclosed polymeric door facing and a method of forming a door facing are also disclosed.
