In these localized applications, several panels may be stacked. In this type of system, the stone is applied directly against and attached to solid masonry backup such as concrete masonry units (CMU) or concrete. A drainage cavity is typically located behind the stone panels to collect and divert to the exterior water that penetrates through the joints.įor certain applications, such as at building entrances and near grade level installations of limited extent, the stone system may not incorporate a drainage cavity but instead be a barrier system. ![]() Joints at the perimeter of each panel are usually 3/8 inch in width and are filled with sealant. ![]() Typically each panel is independently supported to the building structure or back up system using an assemblage of metal components and anchors. However, maximum panel dimensions are usually approximately 3 to 4 feet and usually not more than approximately 6 feet. Overall panel dimensions can vary significantly for different buildings, depending on the strength of the stone used and architectural affect desired. A common panel thickness is 1-3/16 inch (3 cm). Most panels are fabricated from granite, while marble limestone, travertine, and sandstone are also used to a lesser extent. Thin stone wall systems used for exterior building envelopes typically consist of stone panels ranging in thickness from 3/4 inches to 2 inches. ![]()
