Re: 2x4 stud walls in High Wind areas

[Subject Prev][Subject Next][Thread Prev][Thread Next]
What grade lumber are you using for the 2x4 studs when checking the stresses?
The framer is going to use "stud" grade no matter what you specify and I doubt
you will get the studs to calc out using those stresses. Stick with the 2x6
studs in a high wind/Exposure "C" area.
