Finding Structual Wood behind Drywall
I thought I had posted on a similar subject about a week ago, but I didn't receive any responses, and I can't find it. So, I hope this is not a duplicate.
I am planning to install a simple crown molding in a bedroom with 8' ceilings. The house is about 25 years old and has current wood framing, I believe.
I believe the (second floor in a two story home in this case) wall has a double 2" by 4" wood plate on top of the wall studs. Taking the real dimensions into account that would mean the top of the wall frame has a 3" wide wood backing where the ceiling joist rest. Given a half inch drywall ceiling that would mean the finished wall would have about 2 1/2" of wood below the finished ceiling. Thus, one could drive a nail into the wall anywhere from the ceiling to about 2" below the ceiling and be sure of hitting structural wood with the nail. Is this correct?
I may not have clicked on the post I think I made and that's why I didn't get any email notice of answers/inputs.
