Underfloor heating - no heating loop over thermal insulation stone

Hello everyone,

from your point of view, is it normal that no loop of the underfloor heating is installed over an insulation brick?

On the ground floor, at the doors to the terrace, the substrate directly in front of the doors is an insulation brick (aerated concrete). Exactly there (so it only affects 20 cm) no underfloor heating is to be installed because the area is insulated.

Is that understandable and even sensible?

Hmm, at my construction site the underfloor heating is laid particularly densely exactly at this spot... because what does it matter to the stone, there are 10cm of insulation and impact sound insulation on top anyway... so the explanation is not really convincing...

Is that comprehensible and even sensible?

For me, hard to understand. Downwards ("above a stone"), the underfloor heating is insulated. Is the stone within the insulation layer? When the heating pipes are laid, the subfloor is level. I don’t understand your planning.

Hello,

I found something on the internet on this topic



Have a look and read a bit.

Best regards

Hello "Krusty".
There are no specific regulations in relevant standards for the installation distances of heating elements in front of floor-to-ceiling facade parts.
However, it is correct that the heating elements are usually laid more densely in front of such facade parts in order to intercept convection of cold air at window surfaces in these areas.
But at an installation distance of about 20 cm, there is no reason to "rub your eyes"! Nothing happens there.
It is also correct that in these areas, from a construction point of view, the thermal insulation used in the floor should increase in thickness in a wedge shape, as thermal bridges from the exterior are intercepted by this.
And aerated concrete has good thermal insulation properties.
The notes along with the sketches, which the "readers" presented, were apparently not understood by the person themselves.
Because it has nothing to do with the "problematic" you described and was taken from some literature source, which in turn clearly refers to DIN 18560 Part 2 (the screed standard for floating screeds and heated screeds).
I think you will most likely be able to "live" with my explanations, right?
