ᐅ Insulating plastic fittings/water pipes and underfloor heating under the screed?

Hello,
as shown in the two photos, the hot and cold water pipes are insulated. The plumber says the fittings (connectors) do not need to be insulated because they are made of plastic. Is this correct, or could this cause problems regarding thermal insulation, condensation, or noise?
The pipes are located under the screed, meaning there will be polystyrene insulation and a self-leveling screed on top.
The plumber suggests he could wrap fleece over them, but says it is not necessary. What is your opinion?
Best regards, Andreas

Also, PU foam does not expand when dry if water is added... by the way, there are different types of foam available.

There are fastening guidelines, and I must have overlooked the line about the PU foam.
What do you do if the pipe detaches from the PU foam while pouring the screed?
Doesn't the PU foam even deform the surface of the wastewater pipe?
Please never advise users on house building.

Regarding the PU foam: From the pictures, I see it more as a base layer for the slope rather than as a fixing. As the sole method of attachment, it wouldn’t be acceptable to me either...
