Panelization has been shown to reduce construction time for production builders. It also can easily utilize advanced framing techniques which reduce lumber costs providing further benefits. The consulting team worked with builders, panelizers, and manufacturers to develop specifications for factory-built wall panel systems with an integral air barrier and exterior insulating sheathing that could meet the needs of production builders. The team worked to verify and develop factory specific assemblies and onsite construction procedures to ensure the quality and market potential for an exterior insulation and air barrier panelization system.
