Embodiments of a system (50) and a method for manufacturing a cementitious panel (10) can be used to produce a cementitious panel (10) having a multi-layer air/water barrier membrane assembly (18). The layers (21, 22, 23) of the membrane (18) can be built up via a series of applicator stations (72, 75, 78) applying a fluid composition using roll coating, for example. Between applicator stations (72, 75, 78) 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 (10) can be conveyed through a cooling tunnel (93, 103, 113) after each drying section (92, 102, 112). Se pueden usar modalidades de un sistema (50) y un método para fabricar un panel cementoso (10) para producir un panel cementoso (10) que tiene un ensamblaje de membrana de barrera de aire/agua multicapa (18). Las capas (21, 22, 23) de la membrana (18) se pueden construir a través de una serie de estaciones de aplicación (72, 75, 78) que aplican una composición de fluido mediante recubrimiento con rodillo, por ejemplo. Entre estaciones de aplicación (72, 75, 78), la capa aplicada de composición de fluido puede someterse a condiciones de secado mediante calentamiento por infrarrojos. Para ayudar a proteger de los efectos nocivos del calentamiento por infrarrojos, el panel cementoso (10) puede transportarse a través de un túnel de enfriamiento (93, 103, 113) después de cada sección de secado (92, 102, 112).
