An acoustical ceiling roof panel assembly including a plurality of roof deck panels assembled in side-by-side relationship and secured to roof supports with each panel including a plurality of parallel and spaced apart perforated flat sections. Each flat section is separated from its adjacent flat section by a rib section, and has a width at least three times and preferably five times greater than the width of the rib section as measured in the plane of the flat section. Lengths of insulation are positioned between adjacent ribs so as to substantially fill the space formed by the adjacent ribs and the flat section. A wire mesh spacer is positioned within the space between each perforated flat section and the insulation to maintain the insulation in spaced relationship to the flat section.
