Hello, during our new build in 2017, I only just noticed in the photos that the insulation boards in the floor structure were not bonded (sealed) together. The edge insulation strip was also not sealed to the insulation boards. The underfloor heating pipes were seemingly “stapled” directly in place, and then the liquid screed was poured.
Now we possibly have hidden mold within the floor construction.
Who is responsible for inspections and any further necessary actions?
Thank you

We didn't glue anything there, but the entire underfloor heating system was installed differently. However, only Styrofoam boards are underneath.Wow, those are really large spacing distances. Someone must have based the heat load calculation on standards from the 1980s.Alessandro schrieb:
Why would the floor mold? With underfloor heating, everything is dried out. Mold doesn’t stand a chance there. Silverfish have a different origin. Because water runs from the screed under the insulation boards and cannot dry properly there, even if the screed is dry. But I am not an expert. I have just read several times that this can cause major problems and is not that uncommon.

District heating—they have already complained that we require below-average energy consumption.
The pipes were installed according to the manufacturer’s calculation. In the bathroom, the circuits are close together due to the higher room temperature.I actually believe you, but it is still not ideal because, as I mentioned before, this will cause you to heat unnecessarily with a higher supply temperature. As a result, your heating costs will be higher than needed.It’s okay if you don’t understand what I mean. You will understand once you want to optimize your heating system and wonder why some operate with a supply temperature of 25°C (77°F), while yours runs at 30°C (86°F) or higher.
