Offer(s) for a new building

You are building - somehow - in the commercial area, right next to a carpentry? This brick is useless in terms of soundproofing, even with ETICS, with its ridiculous 750 kg/m³ bulk density, and is basically on par with a similarly inferior Ytong block.

Did the building authority approve the wall thickness in the commercial area without complaint? That would crown all absurdities even more...

Next to me is the warehouse, you can hardly hear the production (which is on the other side of the warehouse).

But you’re not going to have 17.5 cm exterior walls now, are you?

ööööö, ist bisher so geplant .....wie sollte denn diese sonst sein ?

Are you getting clinker? Then I'm out on how that will be implemented. But an exterior wall is basically made of bricks no less than 36.5.
