Added insulation on outer wall "hanging"
Hello everyone!
I have a small wooden house that has been additionally insulated from the outside with 45x95 studs outside the existing old studs in the frame. The new part thus "hangs" outside the foundation wall of the crawl space. All the studs are screwed into the old frame, but there is a lot of weight without any solid support.
How should one prevent the wall from sagging over time? Install some kind of angle bracket on the wall up to the horizontal stud? Reinforce with something like paving stones from the ground up to the stud with sill flashing in between?
Should the horizontal 45x95 stud at the bottom be clad with sill flashing or painted?
Best regards, Jonathan

It won't be as much weight as you imagine(!) screw with long screws into the existing load-bearing structure and that should be enough! The pressure created by the screws transfers the force to the structure.
Okay, but I think I can see a gap at the top by the window in the bathroom since the wall was put in place. Is it because the new wood has moved maybe?
The old frame was quite weak. Slightly different timber thicknesses but mostly around 45x50. I think the cabin was built in '62.
Thanks for the quick response😊

The question is not relevant. The added construction only needs to support its own weight, which is quite small in this context, amounting to a few tens of kilograms per square meter. A single sturdy screw or nail might handle 100 kg. The old framework, on the other hand, has to bear the loads from the floor and roof, which is something entirely different.
Okay. Thank you so much for the answers.
But the next question then, should it just be painted underneath or should some other kind of protection be used? The wind protection is stapled a bit onto the rule.

Brush away the debris and secure the tarp a bit better. You can leave the rule as it is. Wood that is not exposed to sun or precipitation does not require any treatment.
