Which is better 2×4 or 2×6 studs?
There is a school of thought that the larger 2×6 studs will conduct less heat outside than 2×4 members, both because there are fewer of them and because they are thicker, front to back.

Which is better 16 ” or 24 ” stud walls?
I agree that 16″ o.c. stud walls don’t use a significant amount of material more than 24″ o.c. walls, in most cases, but they do use more material, and the extra studs don’t contribute greatly to the building’s ability to withstand design loads, so again it comes down to builder preference, at least for one- and two-story buildings.
What’s the difference between 2×4 and 2×6 stud walls?
He said that whether you frame with wood or steel the wall should be 2×4 with extra insulation on the exterior because of the dew point. With a 2×6 wall the dew point is at the middle of the wall whereas with 2×4 and insulation it would be much closer to the outside of the wall cavity. We require R20 in walls in this area.
Why are off setting studs better than 2×4 framing?
Off-setting studs of any width decouples the two sides of the wall, so for sound to pass through, it must vibrate the wall on one side, be transferred to the air gap between the two and then cause the wall on the other side to vibrate and in turn to cause vibrations in the air in the other room.
What kind of insulation do I need for 2×4 stud walls?

Comparing apples to pomegranates, the double-stud wall can be made as thick as you’d like, with incrementally greater resource and energy savings. Splitting the plates and setting band joinst on the interior wall will dramatically increase the thermal efficiency of the envelope.
