ᐅ Which type of screed do you prefer?

I just noticed the compressive strength today:

Maxit: compressive strength after 28 days ≥ 30 N/mm² (megapascals)
Hasit: compressive strength after 28 days ≥ 25 N/mm² (megapascals)

At some point, we want to have a stove built in the living room...

Where a heavy stove is going to be placed, you should avoid using EPS insulation or similar materials there. If insulation is necessary, partial use of XPS insulation (thickness/height depending on the surrounding floor construction) combined with a cement screed is recommended. Naturally, the heating pipes of the underfloor heating should also be omitted in that area. This advice was given to us by the specialist trade consultant. However, this obviously depends on the stove and its weight. A 150kg (330 lbs) freestanding fireplace can stand on a conventional floor structure, but a handmade stove weighing over 500kg (1100 lbs) places higher demands on the load-bearing capacity of the subfloor. When is your screed scheduled? Have you discussed the fireplace issue with your builder so they can plan and execute accordingly?

In two weeks. We said we want to have a stove built once everything is finished and we have saved up a bit again... That’s why the construction company installed an Erlus chimney in the middle of the living room... I assume this has been taken into account, or should I ask again?

Yes, I would definitely discuss how the area around the fireplace will be constructed. We decided on a compromise: a conventional floor structure but without underfloor heating in this area. This means heavy stoves are not possible, but a freestanding fireplace is still feasible.

Well, we definitely want a built-in fireplace, not a freestanding one.

This is roughly how we imagine it...

Just came to mind...

There is a 1000 liter (264 gallon) storage tank in the utility room... Should the underfloor heating be omitted there as well? The underfloor heating plan doesn’t mention anything about this, at least.
