What’s Inside a Stud-Framed Wall
The only time you may ever concern yourself with a wall stud is when hanging a mirror or painting. Remember most studs are 16 to 24 inches apart on center. So when you find one stud you can always locate the adjacent one. But what is really inside a wall?
Tear back the drywall and you’ve got the studs, insulation, wiring and possibly venting. No real mysteries.
