Hello
I'm just starting to furnish the upper floor of the house.
Between some of the rafters, it's CC1200 and between others it's CC600.
Now that I'm going to add to the rafters and posts, maybe I should also put in a couple of additional vertical studs along the long side so I get CC600 between all the posts? Or is it enough with CC1200 between rafters/posts and then screw in 45x45 horizontal studs with CC300, and attach boards/gypsum to these for, e.g., wet rooms etc.? Or does it need to be CC300 between the vertical studs since the horizontal ones might be too weak if they have too few attachment points?
