Air gap nail battens

[Fredrik Lindahl]

Hi!
I'm setting up battens for mounting the exterior cladding on my house and realize that I might have bought battens that are too thin (22mm). Is this air gap sufficient, or do I need to redo it?

Sufficient enough, as long as you have wood behind the battens because it is too weak to support the panel when nailed...

More than enough, as long as you have wood behind the battens because they are too weak to support the panel when nailed..

Thanks for the quick response I have attached the battens horizontally on vertical studs 220x45 with 60 cc but guess this will be too weak when it needs to be nailed? @Rejäl

Yes, a 22x45 will crack when you nail the panel, the smallest dimension usually used is 28x70..

Okay, then I probably need to redo it.

...and it doesn't help to screw on the outer panel? It will still crack? @Rejäl

…and it doesn't help to screw on the outer panel? It will crack anyway? @Rejäl

Doesn't matter as far as I can tell, unfortunately...

Another problem in such cases with 22mm spikläkt is that the nail/screw is likely to go through the läkten and puncture the wind barrier (if one is used).

Yes, I realize that too. When I now take off the old battens, can I use the same nail holes when I attach the new ones? I don't need to install new wind paper as well? @Gabbe1

You can tape holes and cracks with windproof tape.
