The developer writes this in his construction description, 17.5 cm sand-lime brick with approx. 12-16 cm thermal insulation composite system (WLG 035) is that sufficient or is it simply the cheapest solution?
The developer writes this in his building description,
17.5 cm lime sand brick with approx. 12-16 cm external thermal insulation composite system (WLG 035)
is that enough or is it simply the cheapest solution?
You have to free yourself from the idea that someone here in the forum can answer this question. You only know if it fits once the KfW certificate has been provided, if you want to build according to KfW 70. If not, you will have to reckon with additional costs due to deviations from the building description.
Basically, 17.5 cm plus 16 cm ETICS should be enough; although I would never build it that way ;)
Thank you for the information. I have no idea about construction, I'm just trying to get informed. But according to my initial research, it's not as easy as I thought. Yes, great if that's enough! What would you choose? I only have the choice between lime sandstones and perforated bricks there, at least according to the building description:rolleyes:.

It would also be strange if it were; then nobody would need to learn a profession anymore ;)
What would you choose? According to the building description, I only have the choice between sand-lime bricks and porous bricks there.
Me? I build exclusively monolithic :D
However, if your favorite option prescribes this structure according to the BD, you will hardly be able to do without ETICS; especially if you want to buy house and land from one source.
KS + WDVS is probably not the cheapest solution. In my personal opinion, however, the best. Good sound insulation, good heat protection (both naturally depending on the RDK), and solid walls. The 17.5 + 16 are, of course, at the lower end.
