New ceiling, material and advice?

[swetrixie]

I have a detached house from '55, with lightweight concrete walls, and originally had a stretched fabric ceiling. I'm now renovating a rectangular room about 330 x 310 cm with one window, one door, three concrete walls, and one plywood wall.

I've torn down the fabric, and there's tongue-and-groove boarding up to the cold attic, with 3/4" battens on the outer edge that the fabric was nailed to. I'm thinking of removing the existing battens but keeping the tongue-and-groove.

Initially, I thought about installing battens and drywall, but are there better alternatives?

Battens, 30 cc I've read?
28x70? (no spots planned)
Battens across the rafters?
Screw long screws where rafters are, the rest into the tongue-and-groove with shorter screws?
A "row" of battens along the walls as well?
Drywall, what width/thickness?
There's a ceiling outlet in the middle of the room, no box, just a metal pipe. Should it be replaced with plastic pipe/box? (Planning to bring in an electrician to replace the electricity and get it grounded.)

Thanks in advance!

Wood paneling would otherwise suit your house well. It comes pre-painted and is relatively easy to nail up against existing battens/studs.

Directly onto the råspont? There are only 3/4" studs along the walls now. How is the wood paneling installed, and what about joints and screw/nail holes?

This is what it looks like right now. The råspont is laid across the roof trusses.

It works well. Panel is nailed in 'nåten' = invisible nails.

Purchased 28*70 glespanel, and decided on gypsum. The ceiling is not entirely straight, but I don't think it will be noticeable, considering the door/window placement and the size.

Do I need to install a vapor barrier before attaching the glesen? Cold attic above, with sawdust, some form of paper, and then the tongue and groove boards.

In which direction should I install the glesen? The existing tongue and groove boards are perpendicular to the rafters.

If you haven't plastered before, get help from someone who has done it before, as it is difficult to make a ceiling look nice.
