Framing & StructuralQuestion 313 of 700
When a pipe notch or bore in a wood stud leaves less than 1-1/4 inch of wood between the pipe and the exposed face, what protection does the code require?
a.A steel plate or shield of adequate thickness over the area to guard against fastener penetration
b.Nothing, provided the pipe is copper
c.Doubling the drywall thickness
d.Filling the notch with expanding foam
Explanation
Where less than 1-1/4 inch of wood remains between a pipe and the stud face, a steel nail plate (typically at least 16 gauge) must protect the pipe so later nails or screws cannot puncture it. Pipe material, extra drywall, and foam do not stop a driven fastener from reaching the pipe.
