From when can one hang pictures in a newly built house?

you can also measure the humidity and temperature.

HKV=heating circuit distributor for underfloor heating.

I only know it as such that in old buildings you should keep some distance from the exterior wall. In new buildings, it should not be a problem if cabinets stand right up to the wall. I have never given any thought to pictures... ops:

Our pictures initially curled. They then always had to hang down for a day and then be rehung. After the summer was over, the problem resolved itself. So it is not made up.
