Abstract: Embodiments of a system and a method for manufacturing a cementitious panel can be used to produce a cementitious panel having a multi-layer air/water barrier membrane assembly. The layers of the membrane can be built up via a series of applicator stations applying a fluid composition using roll coating, for example. Between applicator stations the applied layer of fluid composition can be subjected to drying conditions via infrared heating. To help protect from the deleterious effects of infrared heating, the cementitious panel can be conveyed through a cooling tunnel after each drying section.
