Hello everyone,

I am currently considering building a duplex and am looking for ideas on how it could or should be constructed to ensure a sustainable building in the long term. Of course, it also has to remain affordable.

On the internet and from building planners, you often hear that "this particular method" is the best, depending on the preferences of the contact person. Perhaps someone here can share how they built theirs or what could be done better or differently, so I can get a clearer picture for myself.

Thanks in advance to everyone who takes the time to help!

Best regards,
Dirk78

You need screed whether you have underfloor heating or not.

Take a look at Tecalor TCO 2.5 or Stiebel Eltron LWZ 604 air.

No. Not with a Swedish slab.

Is the insulation then sufficient?
We have insulation below and above the concrete slab.

Where will Katja be installed?

How will you handle different floor heights and thresholds?

How should the ventilation be installed if you plan to heat via the ventilation system?

Recessed floor outlets?

Impact sound insulation.

With a Swedish panel, there is apparently 20-22 cm (8-9 inches) beneath it.

How much do you have?

Do you have a passive house?

Katja, probably between the layers of insulation

I don’t really need many different thicknesses of floor coverings. But it would probably be possible if planned early enough.

Is your ventilation ductwork embedded in the screed? Apparently, it’s more common in walls and/or ceilings.

Floor outlets need to be planned early on, just like with screed.

Does anyone have experience with such a panel in a passive house?

I don’t remember exactly how much.

The insulation and the floor slab are 50 cm (20 inches).
Katja
8 cm (3 inches) of loose fill, 7 cm (3 inches) of floating screed for soundproofing.

Yes, we have a passive house.

Does the Katja splint between the insulation layers make a difference?

Tiles, laminate, parquet, etc., have different thicknesses. Is it possible to level that with the floor slab?

Since the heating system heats through the floor, the supply air is in the floor. Warm air rises and does not fall. The exhaust air is, as usual, located in the ceiling.

I don’t think floor sockets fit into the floor slab; the housings are quite deep.

Don’t fixate on one system. You are working with the floor slab that the builder is capable of or familiar with.
