Generated explanation

Two cutaway wall assemblies compare gypsum lath with drywall on wood stud framing. The upper assembly shows small 16-inch by 32-inch gypsum lath panels fastened to studs and covered with two or three coats of plaster, with peeled-back layers exposing the construction. The lower assembly shows larger drywall sheets fastened directly to studs, with a taped joint between adjacent sheets. Annotations identify typical drywall sheet sizes and a typical thickness of 1/2 inch, with a range from 1/4 inch to 5/8 inch. No defects are depicted.
