Furring can be made from metal or wood.

• A. Metal only
• B. Wood only
• C. Metal or wood
• D. Plastic

Answer: (C)

Furring is a framing method used to create a level, plumb surface for attaching finishes like drywall or paneling, even when the underlying substrate isn’t true. It can be made from either metal or wood, which is why this statement is correct. Wood furring strips are simple, inexpensive, and easy to cut on site, making them a common choice in many residential applications. Metal furring channels (such as hat channels or cold-formed steel) offer precise dimensions, reduced warping, and fast installation, which are advantageous in commercial drywall work. Plastic is not a standard option for typical furring in construction, so the usual materials are metal or wood.
