Hello everyone,
I learned about the topic of screed reinforcement during the customization process for our prefabricated house:
(Excerpt from the document we have to/will sign)
As part of our duty to inform, we point out that cement screed must be reinforced to support tile installation. Suitable options are AKS mesh or fiberglass additives; these must be ordered separately. If this additional service is not agreed upon, warranty claims for any possible cracks in the tiled surface are excluded from the outset.
The surcharge for fiberglass reinforcement is 8€/sqm (8€/sq ft).
What do you think about this?
THANK YOU for your feedback.

@ immermehr: A so-called "screed reinforcement" is no longer required according to any screed standards, and for tiles and slabs it is currently optional.
From the practical perspective of an expert: In the past, there were quite a few screed failures caused specifically by the installation of alkali-resistant glass fiber (AKS) mesh. The term "fear rebar" was indeed justified, and for several reasons.
So-called screed reinforcement made of alkali-resistant fiberglass mesh still makes no practical sense today! They cannot be installed where they would actually be useful, that is, in the lower tension zone of the screed mortar. In the middle of the screed, they make no sense at all, and on top of the screed surface is the compression zone with the least bending — so: they really do not make sense there either.
Short answer to your question: No, it is not specified anywhere in the standards and practically speaking, it is pointless!
