ABSTRACT:
A cementitious panel is provided with spaced inner and outer surfaces connected by edge surfaces. A waterproof film forms longitudinally extending cavities within the panel, with the cavities being laterally spaced from each other and spaced from the inner, outer and edge surfaces of the panel. Expanded lightweight, inert granular material substantially fills the cavities, and a suitable film closes off the ends of the cavities.
When necessary or desirable, the panels are temporarily secured in position adjacent a member and in end to end relation to enclose it and provide fire protection. Holes are drilled through the panels at predetermined locations, and metal studs are inserted through the panel to contact the enclosed metal member and the stud is the welded to the member so that the end of the stud projects outwardly beyond the panel surface. The panels are then secured to the stud end projecting therethrough to enclose and provide fire protection to the member within the positioned panels.
