Standard profiles for ATAS wall panels include ribbed, corrugated, tiled, and perforated. Panels can also be curved, or tapered, with fasteners exposed, or concealed. ATAS wall panels are available in over 30 standard colors, and textures for flat panels can be either smooth, or embossed to mimic a masonry stucco wall. ATAS also produces perforated solar air heating, and drying panels, which are mounted a few inches offset from exterior walls to reduce cooling load in the summer, and create heat in the winter. Insulated metal panels are also available, with optional fire resistance ratings of on, two, or three hours.
