Insulate directly on log wall without air gap indoors?

[Rohdin]

Hello

An old holiday home looked like this from the outside:
outer panel
building paper
logs
some mortar
tretex

Now it will be converted into a year-round residence, and all the interior walls have been stripped down to the logs, and we plan to do it like this directly on the logs:
building paper
45 studs
45 insulation
plastic
17*95 or 20*120 raw board as the surface layer

The question now is whether we need an air gap between the logs and the building paper? Or are the "channels" that naturally form between the logs sufficient?

There is no reason to have an air gap (nor wind barrier as it already exists).

Why should you have plastic? That's where you usually have the wind paper. Check out some log house manufacturers, they usually have good pictures on their websites showing how they do the insulation.

Ah, I thought you were going to insulate the outside, in that case, you apply the wind barrier before the facade. But check out some manufacturers anyway, they have good pictures/drawings.

Ok thanks
How is it really with the plastic?
Does it seem okay to apply it?

Plastic is sensible but only if you can get the whole house wrapped; if any external wall or roof remains unwrapped after your renovation, it's better to skip the plastic altogether.

Remember to install ventilation as well so that you achieve a negative pressure in the house.
