ᐅ Drywall Installation and Vapor Barrier – A Different Approach

It is completely normal and acceptable that the vapor barrier ends on the wooden floor and is glued there with a bead of adhesive.

It would have been sufficient to glue the membrane to the floor only. Especially since, how would the membrane connect to the floor below? Usually, the ceiling rests on the masonry.

Gluing the membrane to the wooden battens in this ceiling construction does not ensure airtightness at all. Warm indoor air can infiltrate through gaps behind the glued membrane into the insulation. Therefore, I clearly see a construction error here. I would definitely not want such an installation. For example, the membrane could have been run from above to the main beam and on the underside of the main beam, it should be ensured that it is also sealed airtight to the wall structure.

This is exactly how it will be done once the rest of the drywall is removed.

The attic will have two radiators per half of the house, connected to the heat pump and equipped with fans. However, since the attic is initially planned only as a backup or storage space, it will not be heated for now. Question: Should there be a vapor barrier between the attic and the upper floor or not?

Somehow, it’s pointless! So I will stay away from this thread as well!

I revoke my statement. With a ceiling like this, where there is no closure from below, that approach doesn’t work.

The concrete ceilings in the basement are currently being skim-coated. However, they should have been primed beforehand. This step was somehow overlooked (due to communication issues with the contractor), so the skim coating was applied without priming. Although I was repeatedly assured that priming had been done. The problem is that the containers are still standing there unchanged for the entire 180 sqm (1937 sq ft) of ceiling area.
Should priming be done now afterward, or should the surface be sanded and then primed, or is it better to leave it as it is?

Pull the plug and let everyone go. Then find a reputable German specialist company with a well-known name and a location in your area.
