I'm checking out different companies... Have reached the roof (starting from the top)
Fiskarhedenvillan has 22 mm tongue and groove boards in the underroof as standard.
What I've heard is that most others have 18 mm or 20 mm. FH is one of the few companies that have 22 mm.
I've also heard that 22 mm was the minimum requirement in the past.
Is that correct??
How much difference do these extra millimeters make??

That probably also depends on the snow zone, roof pitch, and c/C-measurement of the rafters.
It probably works just fine with both 18, 20, and 22 mm - even though 22 mm breathes the most quality
