ᐅ Can you glue drywall directly onto concrete?

Hello,
Can I directly glue drywall panels onto the interior walls of a basement that is about 1 meter (3 feet) underground and made entirely of poured concrete?
Later, bedrooms and a children's room will be located there.
Could there be problems with condensation?
The rooms have windows.
I might also install a ventilation system.

Best regards

will be insulated from the outside


You mentioned 5-10cm (2-4 inches), which is not sufficient. Does the building permit / planning permission classify the basement rooms as living spaces?!

The house is being built in Croatia, where temperatures do not drop below 0°C (32°F), and then only at night.
The basement I am currently using, but only as an office, has no insulation at all, just a 25cm (10 inch) concrete shell and a V3 waterproof membrane against moisture.
It is always 18-20°C (64-68°F) without heating.
Here, it is not common to insulate as thickly as in Germany.

Air trapped behind drywall (gypsum board) has almost no insulating effect because the air must be still to provide insulation. As soon as it can move freely, its function is lost. In drywall installations, the air is not stationary. That is why external insulation systems (ETICS, also known as EIFS) are applied using the point-and-bead method, not just the point method.

The question is different.
The insulation doesn't matter to me; I would only be interested to know if there could be any issues with condensation.

Leave a small gap at the top and bottom to allow air circulation. This way, there won’t be any problems.

I still recommend plastering...
try it on one wall first, and if it doesn’t work out, you’ll hardly lose anything. Okay, maybe a few centimeters (inches) because you would then be attaching the drywall to the plaster.
But what does that matter?
If you can come to terms with that, all the issues drywall might cause are solved at once.
Be brave, it will work out.
