Floor joists

[rutan1]

Hey! How thick should the studs be in a floor when installing underfloor heating? I have 45*200 that I was planning to use for this! Is that enough? I'm thinking about the insulation. Grateful for an answer/ J

Well... 40 skilled byggnissar have read but no one can answer? Or maybe can't be bothered? But at least now I know how to behave here on the forum! Just read everyone's posts, but to reply to something: uh-oh, dangerous, dangerous/ disappointed rutan1

Is it a crawl space or an upper floor? You want to be sure about what you're answering, and unfortunately, at least I can't quite get your question. So, you're planning to frame a floor and on that floor, you want to have underfloor heating?

Then it's usually 195*45 yes, but there are other aspects too, like load-bearing, span, etc. In such cases, there might be load-bearing walls that you can build to support the beams, for example, if the distance to the bearing points is too long. In the case I described now, it's usually a second floor. There are also different qualities of lumber.

Describe a bit better what you're after so you'll get much better answers, no hard feelings, it is Friday after all

Thank you Danne213.. Ok, my information might have been sparse, but it was just a measurement for studs I needed! I got that now from you! It's a crawl space and the ground floor.. The question was really about how much insulation it's reasonable to put when there will be underfloor heating there! No hard feelings I promise

45-195 alt. 45-220 is quite a normal thickness for a floor joist, yes.. The more, the better, of course.

what type of underfloor heating?
how thick pipes?
which system should you use to lay them?

such things also play a big role in how much insulation you need.

If you want help, a little politeness doesn't hurt either.
If you want quick help, call a constructor.

Yes, I went a bit hard, sorry.

Is it really necessary to have underfloor heating on the 2nd floor if you have underfloor heating on the 1st floor? Many say that underfloor heating on the ground floor is enough for it to rise to the upper floor and still be warm enough, especially in houses in central Sweden?

Correct me if I'm wrong, this is just what I've heard.
