Hello,

I am in the process of starting to build my garage/carport, which will have flat dimensions of 700x700 cm. I'm contemplating what type of studs should be used, as the plan is for it to be insulated. At the same time, you don't want to sacrifice floor space for walls ???

I've been considering whether 45x95 with exterior gypsum board as wind protection would suffice, or if one could manage with wind barrier even with these dimensions. Can someone offer some advice...

Since the slab is poured over the entire area, the wall that separates the carport and garage will stand directly on the slab. How do you protect this wall from moisture damage at the bottom?
 
Use asfaboar instead of outdoor plasterboard. Much better in the long run.

Why then?
 
Yes hmmmm why then ???
 
Personally, I've got the feeling that gypsum is what is used nowadays, but if there are arguments for something else, I'm listening....... ::)

You want to build in the smoothest way possible ;)

Can you get by with 45x95 studs? :-/

Yes, it holds, but if you want more insulation, you can place 45x45 studs horizontally as well.

Instead of gypsum, you can use Windy as a wind barrier. It is very easy to handle and convenient.

The wall that will stand directly on the slab can be placed on a layer of Leca blocks. Place tar paper between the Leca and the sill, and it will manage ;).
 
Why Leca? It works directly on the slab, right? (With tar paper in between, of course ...)

I thought, if there was a back slope on the slab, the sole plate would end up a little higher ;).
 
Thinking if it might be easier to cast a plinth that's about 20 mm high, the reason I want to raise the wall a bit is because of potential water that can run off from the car when parked in the carport, not so good for the wall to stand directly on the floor then, I think. :-/
 
I suspected that was what you meant. 20 mm sounds too little, go for 50 mm instead so you can add some rebar as well ;).
 
Do the rebar need to be drilled into the slab at all, or is it enough to lay them along the ledge? ......Right now I'm anxious about whether to choose 95 or 120 mm studs, but I think I'll go with 120 and the windy that immobil recommended, as this seems to be a smooth solution with windpaper.
 
If you do not want standard Lecablock, there is a plethora of smaller dimensions available. You can also use brick, for example. Instead of tar paper, double-folded construction plastic can also be used.
 
The advantage of Leca is that it insulates.
I am going to lay a course with 19*19-leca.
It's quite foolish not to raise the sill.
Moisture goes under the wall and then it rots.
20mm is probably not enough.
Then it's an advantage to get the panel up on the outside.
You want the ground to be at the same height as where the doors are, i.e., at the same height as the slab. If you don't have an extra row of leca, the panel will end up on the ground.

Hello o Hopp,

After many cheerful suggestions, I think it will be a layer with 120mm wide lecablocks against the slab. How do you attach the blocks to the slab, is the mortar enough to keep them in place. :-/
I've seen that there are grooves for reinforcement in the lecablocks, is it something that should be used even if it's just one layer....... ???

How do you then attach the sill to the lecablocks, I was thinking of using an expander directly in the slab but assume it will be a little different when using lecablocks at the bottom. ???

Lots of questions, but maybe I'll learn something in the process.... ::)

120 mm Leca sounds a bit thin :-/
There will be a bit of a thermal bridge at the bottom of the wall, how much insulation did you plan to have?
190 mm Leca shouldn't be wrong, there should be 45 mm horizontal studs on one side or the other, right?

The mortar should be good enough to attach with, I simply smoothed out the recess for reinforcement with the same mortar, I attached the sill with long nail plugs and had tar paper under the sill as well......
