Final answer:
The correct minimum size for nail-on application of wood furring strips over wood framing is 1" x 2".
Step-by-step explanation:
The correct minimum size for nail-on application of wood furring strips over wood framing is 1" x 2". The dimensions of furring strips are typically specified as the width by the thickness. In this case, the furring strips should be 1 inch wide and 2 inches thick.
Using a larger size, such as 1" x 3" or 2" x 2", would be unnecessary and may result in additional weight and cost without providing any significant benefits for the application.
