This paper deals with experimental results on evaluation methods of flexural behaviors out of plane concerning about 2 types of stone facing composite panels with supports of truss structuring plate, truss structuring plate and metal for dry renewals of external walls. The stone facing composite panel with supports of truss structuring plate examined in flexural strength and evaluated by a criterion of more than 7 MPa in effective first cracked flexural strength. And the stone facing composite panel with supports of truss structuring plate and metal satisfied the various kinds of performances such as deformation, durability and waterproofness.
