Design of dry joints in cladding
Dry joints should be designed so precipitation does not pass through them, or the cladding should direct any entering precipitation outward; suitability depends on joint design, cladding design, and exposure severity.
Dry joints between cladding units should be designed so that precipitation will not pass through them, or the cladding should be designed so that precipitation which enters the joints will be directed towards the exposed face without it penetrating beyond the back of the cladding. Whether dry joints are suitable or not will depend on the design of the joint or the design of the cladding and the severity of the exposure to wind and rain.
