Light Weight Stone Veneer Curtain Wall using elastic adhesive and mechanical ties to attach stone to a deck plate frame was developed. Prior to tral manufacturing, elastic adhesive durability, silicone infiltration from elastic adhesive to stone (causing contamination) and mechanical tie fatigue properties were thoroughly tested. Trial manufacturing of spandrel curtain wall panels revealed good productivity and economical merit. Wind resistance test showed these panels to satisfy external wall performance requirements. There are many applications for this curtain wall system.
