Hello!
I was planning to replace the panel on the garage.
It will be ByggMax Baspanel (Tongued and Grooved) 21x120, which will be vertical.
The old panel was nailed with two nails per board and stud.
I have read in a thesis about "constructive wood protection" that you should only drive one nail per board and stud. The nail should be closest to the groove on the board.
Which is correct? One or two nails per stud/board?

I nailed with a spike/spikläkt - zig zag in other words. Then the covers pull towards the panel quite a bit and pinch.
I'll probably go with two just to be safe.

The reason for nailing with only one nail per "board" is to allow the panel some movement... With one nail, the board can move, just as wood naturally does. With two nails, the board is held too tightly and eventually cracks. A facade that is nailed with only one nail per board holds significantly better than one where two nails per board are used...
No, I don't think so. I've been slightly annoyed all day because I've used too many nails (4-5 per board). I really should have fastened the panel with 2 nails per board. For some reason, I've totally forgotten that.
It should be optimal to nail one in the batten just below the top and one in the batten just above the bottom.
I hope it doesn't crack too much (luckily, I've only done this on one side of the house. On the other sides, I've had help from carpenters (who fastened with two nails per board).

Isn't there a risk that it will become too loose with so few nails? Can't the panel become "wavy" when the wood moves if there are only two nails per board?
If I go with one nail per board/slat, then each board is held with a total of 4 nails since I have 4 nailing slats. I hope that will be sufficient...it's half of what was originally used.

Probably depends on where you live as well. Where I live, it would never work with so few nails, the moisture and wind would make it warp quickly and then the problems begin...
Two per board is what I vote for.
Because the boards warp (trying to straighten out the annual rings) to different extents, in different directions, and warp back and forth with variations in humidity.
That's what I believe in anyway...

Doesn't it depend on what kind of panel we're talking about?
From what I've heard, for lockläktspanel and lockpanel, the underboards are nailed with ONE nail per batten along ONE side of the board. The locks and lockläkt then hold the boards in place. Lockläkt is nailed with one nail per nail batten (yes, there's hardly room for more) and the nail should go in the gap between the underboards. I don't know how it's done with lockbrädor...
Spontad panel is probably different since there are no locks holding it in. I stick with 2 nails per board and batten there. But that's just what I think...any other opinions?

Hmm... have we changed the topic in the thread
