Abstract
This invention relates generally to a pre-finished, moisture resistant and durable building material that is able to diffuse stress caused by variations in temperature and climate. One preferred embodiment of the building material includes a fiber cement substrate, at least one resin impregnated paper, and a stress-relieving elastomeric film between the fiber cement substrate and the resin impregnated paper, wherein the elastomeric film acts as a stress relaxer between the fiber cement substrate and the one resin impregnated paper.
