KFW 70 as a goal - which stone?

Hello everyone,

I need your advice.

We have now decided to build more or less "on our own." The financing is secured, and we have the draft of the notary contract for the plot of land... so everything is moving forward.

Yesterday we were at a building fair, and among other things, we visited the booth of a major building materials supplier here in the region.

Since the staff there didn’t really have time for consultation, we contented ourselves with taking some brochures.

So far, we planned to have KS walls built and apply appropriate insulation.

Now we have a brochure from the company Wienerberger, presenting a filled Poroton brick that is plastered only with a thin layer of mineral lightweight plaster.

Unfortunately, there are so many different bricks and designations (T9-P/MW, T8, etc.) that I can’t figure out which brick we can use. Can someone recommend an informative site where I can read exactly which brick is suitable for our house?

Or should I not worry about it and just leave everything to my architect?

Regards Frank

Hello Frank,

Or should I not drive myself crazy about this and just leave the whole thing to my architect?

The question about the "right" stone – which btw. doesn’t exist – has been asked here so often that it makes sense for you to first use the search function here. After that, you will already know a lot more and see things more clearly :-)

Btw. I have personally answered this question probably 100 times already :-)

Rhenish greetings
