Reinforced cementitious panel
First Claim
1. A cementitious building wall covering system comprising a wall support structure, a layer of insulative material and a layer of matting overlying said insulative material, said insulative material and matting being applied to said wall support by spaced apart mechanical fasteners, said matting comprising a bulky layer of open construction formed by randomly directed interconnected flexible filaments randomly looped construction as defined by said interconnected flexible filaments, a continuous layer of hardened cementitious material filling and essentially covering said open construction of said matting, said open construction having approximately 90% or more of its volume normally void and thereby filled with said cementitious material, said matting having a nominal thickness defined by extremities of said loops, said nominal thickness being less than a thickness for said cementitious layer and a hardened finish coat adheres to said layer of cementitious material.

Abstract
A building wall covering system for application to a wall support comprises a layer of insulative material and an overlying layer of matting which is attached to the wall support structure. The matting is particularly adapted to provide structural strength in the cementitious material applied thereto. The matting is of a bulkly layer of open construction formed by randomly directed interconnected flexible filaments. The cement layer is applied to fill the voids in the matting and cover same. A finish coat is applied to the layer of hardened cement material to complete the covering. The system has considerably enhanced impact resistance compared to existing systems.
