Hi! We have bought a house from 1945 and are going to furnish the basement, it's concrete and we are going to put steel studs on the walls. Platonmat, flooring chipboard, and then a click floor on the floor. Now I'm wondering how to do it. They seem to have a lot of different ideas at the hardware store. It's important to have the right air gap. Does anyone know? Regards, Takida :-/
Decorating basement rooms often means trouble...
You should not start with the interior but rather look at the exterior wall (slab? Is there external insulation/moisture protection/drainage/ground conditions/moisture measurement of the basement wall/slab etc. Without knowing these conditions, it is not possible to provide a serious answer on how your particular house will function/react.

The only thing I know is that it was drained in 2002. The person who owned the house is sick, so we cannot ask? We have concluded that the best thing is to install steel studs and then gypsum on the wall, no insulation, and on the floor, platon mat, chipboard floor, and then the floor. My question is how much air gap is needed. Some place the platon mat behind the steel studs, but I have heard that it is better to fold the platon mat in front of the studs. Wouldn't that create a larger air gap?? Or is there something else to consider? It became complicated to explain...but I hope you understand! Regards, Takida :-?
I think ByggaNytt is looking to see if the basement wall is insulated/moisture-proofed. Check the external drainage, is there a Platon membrane? Drainage around the entire house, etc. Built in 1945, so you probably have no previous external insulation, but when the drainage was done in 2002, insulation might have been added. If nothing has been done with the basement, then you probably have just a poured floor on gravel (possibly with drainage pipes underneath), resulting in rising ground moisture. So the first step here is to find out how the drainage was done. Any other water pressure (from hillsides, stormwater, etc.) needs to be checked as well. (Is there moisture today in the walls/floor?)
Another factor affecting the moisture environment is the existing heating and if you plan to change it (e.g., by installing electric radiators/floor heating, etc.) and how the existing ventilation looks.
Adding a Platon membrane to the inside of the basement wall gives you a barrier against any moisture from the basement wall as well (since you wouldn't want moisture getting between the drywall and basement wall without a proper moisture barrier!). It's important to ensure the moisture has somewhere to go, so good/improved ventilation in the basement will be crucial to achieving a reasonable indoor climate, especially if you choose organic materials in the walls/floor.
If you feel uncertain in your evaluation, it's better to bring in a builder for help than to waste a lot of money and time and end up with moisture/mold problems after a few years.
