ABSTRACT:
A fibrous building element such as a panel which can be used for roofs, soffits and walls. The fibrous element is coated on the side which will be positioned on the exterior of a building structure with a material which forms a crackled surface. The crackled surface permits water vapor or steam from the interior of the structure to pass through the panel. The crackled surface presents a surface-active hydrophobic agent to prevent rain, snow and moisture from penetrating the panel. The surface-active hydrophobic agent may be applied to the outer face of the crackled surface coating or may be mixed in the crackled surface coating.
