Wall construction new (vacation) house

[dogpox]

Hello!

I'm thinking of trying out a question here and see what thoughts come in. I'm planning a new build where the idea is to do some of the steps myself. I am in the phase of designing the house and have realized that I need to know details about the wall construction to be able to submit building permit documents.

Originally, I was thinking of plaster + 45 stud + moisture barrier + 195 stud + 45 stud + plaster + panel, perhaps mostly because the house I live in today is built that way.

I wanted to ask for your experiences regarding this, I want the equivalent thickness (or at least sound/insulation value), but I have realized that it might be complicated to have the extra 45 stud on the outside when building with loose timber yourself?

Suggestions? Links? Thanks in advance!

Hello, use Träguiden and you will get good and tested examples of wooden constructions. There are many examples for input to your planning, not just walls.

Replace outer 45 with läkt type 22mm

Thanks for the reply, I have looked at the wood guide for many hours! So the outer 45-rule is replaced with something like this:?

It seems to be more expensive, but perhaps easier?, thinking that this board replaces insulation/frame/gypsum?

How do you think such a board dampens sound compared to frame+insulation+gypsum?

Otherwise, I can't really find any more examples. On YouTube, Fiskarhedenvillan has a series called "så gör snickaren", where it seems they have the load-bearing frames on the outside, and two layers of 45-frames inward. Any comments on that? You can probably set the windows a bit further out towards the wall then, which might be nice? (A slightly deeper window niche). Does it matter structurally?

I don't quite understand your answer Jonatan79, do you mean that I skip the outer insulation layer entirely and nail battens/panel directly onto the wind barrier/gypsum?

Place OSB behind the drywall

 

[dogpox]

Put OSB behind the plasterboard

That's probably how it will be, or wood paneling as a surface layer.

 

[wildeside]

That might be the case, or wooden paneling as the surface layer.

Then you have something to attach the panel to

Now, I intended the thread to focus more on the wall's construction regarding insulation layers, windproofing, and the position of these layers in relation to the load-bearing part, but by all means, I'm interested in this too I spontaneously think that OSB is a bit unnecessary if you have wall paneling, and that you attach the paneling to the studs belonging to the installation layer?

 

[Jonatan79]

YES!

 

[dogpox]

Can you elaborate on this?

 

[Jonatan79]

From the inside: gypsum + 45 rule + vapor brake/vapor barrier + 195 rule + exterior gypsum + 22 batten facade panel

 

[dogpox]

From inside: plaster + 45 stud + vapor barrier/vapor brake + 195 stud + exterior plaster + 22 batten facade panel

But it's nice to have a warm house too, isn't it? Should be a bit warmer with an extra layer of insulation?

 

[Jonatan79]

It is perfectly fine with 45 + 195. You won't notice the difference. Utegips does a little too. The most important things are heating and ventilation. You can ask about that in another thread ;=)

Replace outer 45 with battens type 22mm

No, TS absolutely should not do that. Nailing panel to 22 mm battens is reckless. Should TS use 40 mm nails then?

 

[dogpox]

No, TS should definitely not do that. Nailing panel against 22 mm battens is foolhardy. Should TS use 40 mm nails then?

How do you think the wall should look?
