Interior renovation of cottage roof

[Lars Ryden1]

Hello,
I have a cabin, inherited from my parents, from the 50s.

Now the renovation project has reached the upstairs, and my question concerns making wise decisions regarding the ceiling itself.

The ceiling currently consists of raw wood panels, about 22 mm, and a "Treetex board" (soft fiberboard) directly underneath.
(On the outside, not surprisingly, there is a couple of layers of roofing felt, battens, and roof tiles)

I am considering an interior wood panel on the ceiling, but how do you proceed between the panel and the raw wood to avoid trouble? Avoiding problems is more important than achieving high thermal insulation.

Hello,
Does anyone know how to build a ceiling on the raw tongue-and-groove boards in a summer cottage??

Is there an air gap between the raw spruce and the board? Lay insulation against the board, then vapor barrier, and then ceiling panel.

Hello,
I'm thinking of removing the Treetex board and putting up paneling.
Should there be an air gap and should the paneling be mounted on "battens"?

Should one have an air gap and mount the panel on battens?

It is not necessary, but quite practical if you plan to run concealed electricity.

But no moisture barrier if the house is unheated during winter, as I understand it??
