Hello everyone,
We have just started renovating our future new home and are planning to install underfloor heating. Since the building dates back to the 1950s, it has a wooden beam ceiling, which is common for that period. When researching the topic, it becomes apparent that using the "standard" liquid screed might cause issues with the structural load (weight) and/or door frame heights (floor buildup height).
Of course, we will consult with qualified professionals about this, but I would be interested to hear how you have approached similar challenges or if you have alternative solution suggestions.
Thank you!
Best regards

Hello "ShawN46".
In principle, such a construction is possible, but you don’t have any height to spare! 10mm (0.4 inches) is 10mm (0.4 inches), and the insulation effect of a 10mm (0.4 inches) thick wood fiberboard is negligible, so the available height should be used more effectively.
The insulation for an unheated basement should definitely be installed on the underside of the ceiling!!
What you have uncovered in the meantime is known as a "Prussian flat ceiling," which was a common ceiling type in the 1930s. Quite load-bearing, but the iron beams create a significant thermal bridge from a construction perspective. I had the impression that underfloor heating was supposed to be installed?
To cut to the chase here:
I am currently responsible for planning the floor structure of two large projects with areas up to 6,700 sqm (72,153 sqft), each with limited load-bearing capacity of the ceiling structures in Frankfurt and Berlin.
Perhaps I can give you some tips if you tell me the requirements for your floor. Here, besides the load capacity (kg/m²) of the ceiling, the total available height and type of floor covering are also essential.
