Wall Calculators
Last updated .
These three pages are the wall and the attic finish. Drywall counts 4×8 or 4×12 sheets, screws, joint compound, and tape. Paint counts walls, a ceiling, openings, and trim, in gallons and quarts. Insulation turns an area and a target R into batt layers or a blown-in depth.
Plaster stays on the masonry hub. That page is a cement-and-sand coat, with cement bags and sand volume. It is not the drywall sheet count. The roof over the room is the roofing hub.
