We have a 65sqm (700 sq ft) living room including the kitchen. This can be a single continuous screed as long as there are separate heating circuits, which are evenly heated, right?
Our construction company still wants to put joints between the screeds despite using liquid screed and even heating. So, multiple heating circuits in the living area would mean multiple screeds with expansion joints in between? That shouldn’t be necessary, should it?

Hello,
With liquid screed, it is possible to completely omit expansion joints (not edge joints). The deformation is so minimal that no damage is expected.
If a wall receives a lot of direct sunlight and large-format tiles are installed, an accommodation joint should be included.

We do not know what type of screed is involved.
Regardless, the technical guidelines require movement joints to be installed between different heating circuits and also between different rooms (of a residential property) in the screed. This applies whether it is a flowable screed or a conventional screed!
Omitting movement joints can sometimes "work out."
Damage to the screed is therefore not necessarily to be expected.
With a tiled floor covering, different technical rules apply anyway, as field boundary joints must be installed.
One does not directly relate to the other!
However, the absence of movement joints is a violation of professional standards. This is usually addressed by extending the warranty period.
