ᐅ Experience with Duotherm blocks, used by Kern-Haus

I’m reviving this thread again.

I’m new to the forum and expect to receive my quote from Kern-Haus tomorrow. So far, the impression of their houses has been very positive. We were able to visit a house in the shell stage and another nearly completed one.

Can anyone share real-life experiences? How is living in these houses, and how did the construction process go?

Best regards,
Frank

We are planning to request a quote from this company soon.
Is a "squeaky house" a building constructed by simply assembling prefabricated walls that are already cast?
Similar to Liapor precast walls?

@Bauexperte
You mentioned that one should ask for a Hilti tool.
I assume that was not necessarily a negative comment, as long as the walls are stable, right?

How does this type of block perform in terms of insulation and soundproofing?

Like with Liapor precast walls as well?

No – prefabricated walls are not part of this provider’s concept, although I have seen that they occasionally build in a conventional way.

You have to imagine it like a construction kit. The individual blocks are the shell, which is assembled per floor and then filled with concrete.

I assume that wasn’t necessarily a bad comment if the walls are solid, right?

It means you won’t be able to drill into the walls with regular drills.

I wouldn’t really call it a block. However, the structural engineer of the provider calculates the required specifications, just like with any other building project.

I wouldn’t exactly call it stone. However, the structural engineer of the provider calculates the requirements, as with any other construction project.

So it sounds like you’re not very enthusiastic about this "stone"?
What would you recommend? We are still open to all options.
Which solid construction builders can you recommend?

We once considered building with Kern-Haus. Although it was four years ago, the system probably hasn’t changed much. There are show homes in Ransbach-Baumbach, near us.
A colleague built with them three years ago because he found their building method interesting.
Today, he wouldn’t choose to build that way again. He struggles to keep the house warm during winter. He installed an air-to-water heat pump with an additional electric heating element, which runs continuously throughout the winter.
He lives in the Westerwald region, where it can get colder than in the Rhine Valley.

If choosing Kern-Haus, why not build yourself? With Euromac, you can also assemble your own building blocks.

I am here to advise and help as much as I can. My personal preferences have no place here and should not influence you or other users in their decisions.

Sorry, but you will have to determine the right wall construction and temporary building partner for yourself.

Are you sure he didn’t rather choose an exhaust air heat pump? With an air-to-water heat pump, the share of the electrical costs for the heating rods accounts for only about 2% of the total energy costs.
