Ceiling question

[aggerospigg]

Hello
I am planning to decorate my upper floor and was thinking of installing groove panels on the ceiling. The rafters are cc120.

- Can the panels be installed directly on cc120, or is the distance too large?
- Is it possible to install it floating, meaning the joints fall between the rafters? It should hold since the panels are tongue-and-groove, right?
- Above the panel, there's a vapor barrier and then 435mm of insulation. Is it enough for the groove panel to support the insulation, or do I need to install battens?
- Can groove panels be used in a bathroom, or should the new rules for wall cladding also apply to the ceiling there?

Thanks in advance/ Niklas

run with sparse panel 22x95 cc 30 over the roof trusses, I did, by the way, are you having the panel lying down or standing up?
in the bathroom, I have sparse panel cc 30 and huntonit boards.

hello
thanks for the reply!
the problem is that I need to have the track panel across the trusses, so the spacing will be two layers if I have to space... is that common or are there other solutions?

I don't know that.

You can kortla between the rafters, 28 mm up from the bottom edge, and then attach glespanel to the kortlingar. 60 cc will surely suffice, meaning one gles between each pair of rafters.

I wouldn't install the ceiling panel continuously (or floating as you write). It simply looks much nicer to install the seams in straight lines.

I installed my ceiling in most of the house continuously since it was already end-matched, but I bitterly regret it now. The seams have dried apart by a millimeter, and since the ceiling is whitewashed, it's hard to conceal them afterward.

The entire childhood home was built with continuous paneling with cc120. I believe it was about 20 mm thick. I would guess it was 22X120 which was then planed and profiled.
