Walls & ceiling for storage?

[Tyresö]

Hmmm, I'm torn between these. I guess it's the simplicity that draws me to OSB, but maybe it's not such a big difference after all!
Do you install the raw tongue and groove directly on the rafters, or do you need to frame up cc60 for this as well?

It works with 22 mm raw tongue and groove directly on the rafters, but then you should have a rule that fixes the tongue and groove to each other (c/c 60) between/along the rafters. Without proper framing, there is a risk that it looks and wobbles as if Martin Timell built it.

Haha, you definitely don't want a Timell construction
Now it's decided... råsponten it will be!
An incredibly big THANK YOU for this valuable help! Now it will be correct and proper from the start!!!
