Abstract
A laminated curtain wall panel is prepared by continuously disposing foam boards onto adhesively coated gypsum sheathing followed by a third layer consisting of a reinforcing mesh and a cementitious binder, as the product progresses on a conveyor. The laminated product is erected by screws which are forced through the panel by a screw gun which disposes the screw head firmly against the gypsum sheathing.
