Experience with Duotherm stone, used by Kern-Haus

[Kern-Haus] doesn’t seem to come off particularly well. Too bad, I also had them on the list. Would [Weberhaus] be preferable then?

We only wanted to get an offer from Kern-Haus. Unfortunately, this turned out to be like a marathon.

Four very long conversations with a saleswoman who hardly knew anything about construction.

Our floor plan was already fixed, we only wanted a total price for the construction.

First, we had a kind of initial interview, everything was neatly recorded in a booklet, then there was a conversation with a financial advisor to see if we could even afford it (if it would be worth Kern-Haus investing more time and money in us).

We NEVER took plans home to check if everything was correct. And the final sum was also just roughly estimated for us.

We NATURALLY HAD to look at a finished house before the conversations continued. There was no way around it.

The homeowners were also quite satisfied with everything (just moved in). The check for the viewing was signed right in front of us. That could be handled differently.

Better choose a regional general contractor before going to large house-building companies. My recommendation.

Year of construction: 2014
Construction method: Duotherm (styrofoam block system with concrete core) by and with Kern-Haus

Moisture in the house and intense sound transmission - construction problem of Duotherm!

Unfortunately, we regularly have moisture in the house.
Specifically, it appears at a window element next to the front door and flows inside in a trickle along the window. Corresponding consequential damages to wallpaper, possibly floor etc., are preprogrammed.
Unfortunately, this seems to be a construction problem of Duotherm.
Our site manager says: "Well, the water flows through the tubes that connect the Duotherm stones. It flows in somewhere and comes out somewhere else."
Consequently, Kern-Haus has so far not been able to get the problem under control.

Furthermore, the construction method is unusually loud. Presumably, the interior plaster is more intensely stimulated to structure-borne sound by the styrofoam substructure. And this is partly transmitted across several rooms. In our case, even across one floor and from one end of the house to the other.

Based on current experiences, I can unfortunately only advise against this construction principle!

Please also add when you wrote what and what response you have received so far. This way, someone else can better assess the behavior of the home builder. Perhaps you only sent the email 24 hours ago and still have not received a reply.
