Is there any material suitable for creating an air gap behind a plasterboard if you are going to plaster a wooden house? I would like to create the air gap with a strip of more moisture-resistant material than wood and preferably a material that can act as a moisture barrier.
One idea is to place a strip of aging-resistant plastic outside the strip, i.e., between the air gap strip and the plasterboard.
 
Test cable channel. Available in aala dimensions.

The cable trays I've seen are meant for hiding cables in but not strong enough for me to screw plasterboards onto them. Is there any particular cable tray you're thinking of?
 
Are there not special strips for air gaps behind panels? If I remember correctly, I've seen several such in aluminum.

Edit: I’ll browse a bit and see if I can find one again...

Do you want to avoid wooden lath on a wooden house? Are you under the illusion that you can get a completely soaked plaster and plaster-bearing board or what are you after?

If that's the case, the simplest solution is probably just to use standard wooden lath but screw it up with a suitable plastic washer against the structure.

Yep, I thought I wanted the plaster wall to last long, and the spacer batten is the weakest link. But I might be wrong.
If I use a plastic washer, it should probably be placed between the wood batten and the plaster-bearing board, or I could just use a narrow strip of age-resistant plastic on the wood batten to maybe make it last a little longer.

Theoretically, I think you have a point about where the washer should be placed. Practically, I think it's much simpler to put it under the strip during installation, and then when the board goes on, you just need to hit the strip as usual.

However, I imagine that in a scenario where you have such incredibly saturated plaster that you risk moisture being drawn from the plaster-supporting board to the frame, it is probably the extreme relative humidity of the air circulating in the air gap that will increase the moisture load on your frame rather than what can be drawn in by capillary action through the strips. Plaster-supporting boards are usually quite capillary-breaking with

However, I'm thinking that in a scenario where you have such incredibly saturated plaster that you risk moisture being drawn in from the plaster carrier board to the frame, it is more likely the extremely high relative humidity in the air circulating in the air gap that will increase the moisture load on your frame, rather than what can be drawn in with capillary action via the moldings. Plaster carrier boards are usually quite capillary-breaking as well.
yes, thoughts have gone in the direction that it's humid.
And hitting the plate when the plaster is screwed on is unlikely.
But I believe if the plaster is 75, then the wood will be 75, and that's a bit high, but if I have plastic between the wood and plaster, the wood will last a little longer.
The risk that moisture would get trapped inside the plastic is also a possibility, but I think it can move sideways.
