Outdoor gypsum placement, life with foundation?

[JOW]

Short and simple question. I need to make a basic floor plan that will be further developed. I want to achieve a certain interior measurement after the wall is finished.

Slab on the ground. Should the sill be placed edge to edge with the outer edge of the foundation? Or should the exterior gypsum sit edge to edge with the outer edge of the foundation, i.e., should the sill be set back 10mm to account for the exterior gypsum?

No one who knows?

maybe it could be something?

It is not the same core solution for that wall as my walls will be.
Wall from inside out;
- Gypsum
- Wood fiber board
- 45mm installation space
- Vapor barrier
- 170mm load-bearing
- 70mm crossed framework
- Exterior gypsum
- Nail battens
- Wood panel

Or should the exterior gypsum be edge to edge with the outer edge of the foundation, i.e. should you set back the sill 10mm for the exterior gypsum?

To my knowledge, it doesn't matter much on the mm. When I install the sill, I go by the finished interior dimension on the plan, and the slabs are never that exact so the sill can end up 20-30 mm outside sometimes, as much as moving inward. But calculate so that it ends up outside, it doesn't hurt.

To my knowledge, it doesn't matter much in millimeters; when I'm laying the sill, I follow the finished inner dimensions on the drawing, and the slabs are never that exact, so the sill can end up 20-30 mm outside sometimes, just as much inside. But calculating so it ends up outside doesn't hurt.

Is it often the case that the slabs are so inexact that you can't build directly off of them? Should one expect it to be like that?

To my knowledge, it doesn't matter much in mm; when I align, I follow the finished inner measurement on the drawing, and the slabs are never that exact, so the alignment can sometimes end up 20-30 mm outside, or even the same amount inward. But calculate so it ends up outside, it doesn't hurt.

THE EXTERNAL DRYWALL SHOULD NEVER REST ON THE SLAB, IT MUST ALWAYS BE OUTSIDE!!!!!

WHY?
Well, condensation water and any potential leaks through the facade should run outside the slab, which is why it's important that the external drywall is at least 1 cm below the alignment.

If you set the wall and these condensations, etc., occur, then the water will run under the alignment and into the house, which can result in major damage if you're unlucky....

Thanks for the info!

That was not a stupid principle at all. It will be immediately incorporated into my next project.

THE EXTERIOR DRYWALL SHOULD NEVER REST ON THE SLAB, IT SHOULD ALWAYS BE OUTSIDE!!!!!

WHY?
Well, condensation water and any leakages through the facade should run outside the slab, which is why it's important that the exterior drywall is at least 1 cm below the sill.

If you place the wall on the condensation, etc., and if it occurs, then this water would run under the sill and into the house, which could result in major damage if you're unlucky....

Of course, you're right, I got sidetracked on the issue when I thought about the places where it ends up on the inside, :blushing: for example, apartment buildings where you have to follow the life of the entire wall, you then have to place it where it must be. I usually chip away the edge a bit to create an outward slope.

But as I wrote, calculate so that it ends up on the outside. not explaining was weak. Sorry.
