Insulation question

[Datagubben]

Hi,

we have bought a summer house that needs some fixing. Anyway, I have some questions about insulation.

The panel from the outside in seems to be as follows:
There is horizontal paneling, a small air gap, no wind barrier, insulation, then comes the inner paneling (looks like) directly against the load-bearing studs where the insulation is placed in between.

My question is should I do the following from outside in

Panel -> air gap -> wind barrier >insulation -> age-resistant plastic -> air gap -> panel.

I just want to add that I don't have much knowledge about insulation except that if done incorrectly, there is a risk of moisture/mold.

By the way, the cabin is at most 15 years old. I also see that they have used inner plastic for the ceiling.

Grateful for an answer.

Hello. If the building is heated year-round, it can be sealed with plastic, never otherwise. You don't build with an air gap on the inside before the inner panel. How thick is the insulation?

Hi,

There is municipal water, so I assume there should be some heat on during the winter.

But considering the roof is covered with plastic, should I also cover the inner walls with plastic?

The walls are built with 14.5 cm studs and packed with insulation. It looks like the horizontal paneling is screwed directly into the load-bearing studs.

Should I remove the paneling, put wind barrier paper, then some form of nail battens about 2 cm or something, and then put the paneling back?

If you're going to demolish using steam brakes in the walls, that's enough and then you can choose heated or not. I don't know if it makes a big difference, but the outer wall will probably hold better and last longer if you get a windbreak there externally.
