In addition to the price increase and delivery delay of our wood-aluminum windows, we are now also confronted with price increases / supply shortages in other areas.
The roofer mentioned price increases for parapet covers, downpipes, etc. of up to 18.5% starting from 1.7. That adds up per running meter as well. He is now trying to buy everything we need by then. According to him, he currently could not build a roof like ours with the sloped insulation, etc., because the materials are missing. No idea if there is any truth to that.
Regarding ETICS and EPS, I am currently waiting for valid statements. That will become clear in the coming days. So far, we have only dealt with price increases for EPS (20-25%).
However, the electrician has indicated to me that copper cables are now in short supply. He is missing 23,000 m of various types, regardless of cross-sections. It was planned that he would start the electrical installation in week 28. Let's see if that remains the case. Since his company is rather one of the larger ones, for which single-family houses represent a side business, this now worries me.
