Water and Moisture related failures are the greatest cause of call-backs and litigation. In addition, new energy efficient construction requirements are creating wall systems that have much slower drying potential and reduced capacity for inward and outward drying. The result is a greater potential for expensive moisture related wall defects and failures. Steve Easley uses pictures from his forensic experience to examine field failures of cladding systems used in commercial buildings. Steve provides simple, cost effective solutions to prevent water related damage and how to reduce costly defects. This class will also site current research that supports the value for ventilated cladding systems.
