    Abstract

    Leaking in wall assemblies has been shown to be reduced if the air pressure difference across the cladding can be reduced. The EIF system described has been tested to demonstrate that mineral wool insulation can be used to allow the air pressure difference across the exterior coating of the system to be equalized. The mineral wool is vented at the bottom of the panel. Channels are introduced into the insulation to facilitate the speed of pressurization. Testing has also shown the system to be durable.
