What kind of wood is used for framing studs?

Why is pressure treated wood cheaper than framing lumber?

Is pressure treated wood structural?
It’s because the chemicals used to pressure treat wood aren’t safe for humans. This is why non-pressure treated wood is still required for use indoors, and why builders recommended that you only use pressure treated lumber for the support structure of a deck and switch to untreated wood for the surface.
Which grade of common lumber is used most frequently for framing?
No. 2 lumber is the most common grade for framing. Lumber of this grade contains few defects, but knots are allowed of any quality as long as they are well spaced and do not exceed the size regulations.
Does cedar lumber rot?

Can you build a house with cedar lumber?
Answer: Cedar is one of the most attractive and durable types of wood for house construction. It naturally resists damage from insects, moisture and temperature extremes. Others use cedar post-and-beam construction with insulated walls.
