5.5 hours of conversation. Diffusion open or closed?

To get a comparison between timber frame construction and monolithic construction, I recommend having the preferred house calculated by a developer or general contractor. These can be found in model home centers just like those companies you have visited so far. Contact is also possible online. Just try using search engines to find the big companies. Smaller, local companies are usually even cheaper.

Hi, so I read through the whole topic many days ago, yesterday only the one page where your yield is shown.

It sounded like it wouldn’t be worth it.

Who did you build with Wrobel?
As far as I can see, the installation level at Hanse Haus is timber frame, right?

So I believe at our prefabricated house center they only build timber frames.
I contacted many companies, especially architects, maybe got a 5% response rate.
And the local one wants an architect commissioned by me beforehand.

Hello again

At the installation level in the stud, you penetrate the airtightness layer with every cable, every water pipe, and every socket.
I am building my house mostly by myself. I have contracted the shell construction on the floor slab to a local carpentry company.

Note for laypersons:
As far as I know, the airtightness (against outside air) is ensured outside the insulation layer, e.g. by panel materials. The vapor barrier should mainly slow down diffusion to prevent condensation.

Attention layman's knowledge:

Then the airtight layer on the inside of the main insulation layer would not have to be sealed so carefully. Unfortunately, that is not the case - see attached picture (our kitchen - it still looked like that 16 months ago). After that, some wood wool mats were applied on the inside, followed by drywall. On the other side of the OSB board: cellulose / timber frame, then 60mm wood fiberboards (definitely not airtight), then plaster...

Morning Morning

that's exactly right.
Inside airtight Outside windproof
Inside more airtight than Outside
and always with the installation level.
