Red Seal Lather (Interior Systems Mechanic) Practice Exam

What term is used to describe the framing behind drywall that provides edges for attachment?

1. Studs

2. Lathing

3. Blocking

4. Furring

The correct answer is: Lathing

The correct answer is lathing, which refers to the thin strips of wood or metal that are fixed to a framework before the drywall is applied. Lathing provides support and helps create a surface for the drywall to attach to, ensuring that it is properly secured and that there are no gaps that would compromise the integrity of the wall. Studs, while also essential in constructing walls, are the vertical framing members that support the structure as a whole. They do not specifically serve as edges for attachment like lathing does. Blocking refers to additional pieces of framing placed between studs to provide extra support for heavy fixtures or to create a solid surface for attaching drywall in certain areas. Furring is a method used to create a space between the drywall and an uneven surface or for insulation purposes, but it does not specifically describe the framing behind the drywall for attachment edges. Understanding these distinctions is crucial for effectively executing drywall installation and ensuring a sturdy, well-finished wall.
