Which type of screed do you prefer?

Hello, our independent construction supervisor at the time urgently recommended cement screed to us (in case a water damage should ever occur). What can I say, we had the water damage and at least regarding the screed, we were relaxed. Water damage in the utility room due to a broken heating circuit pump (?)... after three years, you just don't know what will happen.

Hello, our then independent construction supervisor urgently advised us to use cement screed (in case of water damage).

Yes, that is a major disadvantage of calcium sulfate screed. Such risks can never be completely ruled out but can be reduced through planning measures. On the ground floor, we have a niche for a vacuum/mopping robot with a fixed water connection and a drain. The calcium sulfate screed was omitted there and replaced with cement screed. In my opinion, calcium sulfate screed generally has no place in the utility room because the risk of damage clearly outweighs the advantages. At the end of the day, however, the water damage in the calcium sulfate screed is covered by the building insurance, only the remediation is simply more extensive.

In the end, the type of screed does not matter - at least in operation. All variants have advantages and disadvantages: - different thicknesses required - different prices - different water sensitivity - different further processing (grinding or not) - different processing (flowing screed or not) - different drying times

For example, I had a classic cement screed with aggregates. It was a) ready for parquet covering in a few days and b) luckily laid so perfectly that no work for the parquet was necessary.

P.S. I have never seen [Zementsulfatestrich] in processing.

Maxit 450 Hasit 465 are the types... I don't care about the screed prices since it's a flat rate. Do I need more energy because Hasit is slower due to being less heat conductive? Thank you

What is supposed to happen with the heat in the screed then? Where should it go? It can only get into the room.

It just requires a higher supply temperature to achieve the same room temperature if the screed/floor covering transports heat worse/slower. Whether you can actually notice this in consumption is hard for me to estimate.
