Thermal bridge or ?

Would like to place a 110 mm drainage pipe in the floor. (for ventilation)
The floor is 170 mm.
This means only 60 mm iso!
The pipe must run when the outer wall and the torpa foundation have no wall in this area.
You can look under the house right here,
This should mean it will be extra cold in this area.
The pipe is about 1.5 m in the exposed area.

Is this a problem?

Now I might be missing something, but if you have it clean under the house, then why not lay the pipe further down?

Well... it goes up a bergsklack which makes this impossible.. (difficult to describe) Only works if you put it in the bjälklagret Anders

Aha, that caused a bit of trouble, yes.
