So 500 Styrofoam discs (dowels) including matching Styrofoam cutters cost about 25 euros in specialist shops. The builder really shouldn’t worry about that.
And as I said, especially in the area of ETICS, rip-offs are very often observed. What is supposed to cost 136 per sqm?
I would like to see the calculation in detail. Exactly the same crap as with photovoltaic systems.
But don’t worry, the construction is currently collapsing. And really so. In 6 months at the latest, you will be able to build for half the price.
And please write me the exact material costs for 1 sqm of ETICS and the labor costs.
A realistic price would maybe be 50 euros per sqm. And that is already a lot of money for it.
