Questions about trusses at an angle, and construction of a floor level?

[patriklarsson]

Found a house on hemnet now at 113 sqm, heated with a heat pump and electric radiators, electricity consumption/heating 23000 SEK/year and another one at about 120 sqm with a heat pump and wood boiler with heating 14500 SEK/year. I think that if I can keep 12 sqm heated +10 degrees when it's -10 outside (coldest month this winter) and that space has half as much insulation in the walls and ceiling as the house would have, and you also have a heat pump in the house instead of direct electric heating, then it shouldn't take 15000 kWh/year but maybe it does. Does anyone know if there are figures on how much you save with different thicknesses of insulation in walls and ceilings, for example?

If you are building with a vapor barrier/plastic, how should you handle the wall studs if you are building according to the previous drawing, at the red marking on the following sketch?

I had a similar problem with my garage around the roof trusses, but there I am not using a vapor barrier, instead, I am using windbreak fabric and it doesn't cover in the same way.
For example, when building with an elevated wall line or whatever it's called, would it be easy to seal the entire space with plastic, maybe an easier solution?

I don't know how the construction usually looks when you have two skillion roofs back to back. But one way is to lay the lower roof's beams on a wall plate, build up a new wall with a new wall plate for the higher skillion roof. Then you should be able to pass with plastic between the lower roof's beams and the wall plate before building up to the next wall plate.

So, this new wall is placed on the top plate, and it won't be very high, just up to the next roof...

Ok, would it look something like this then you mean?

and if so suitably the plastic like this: (if you build the first standing wall on the slab).

However, I don't know how it will be out at the ends of the left part, if it should end inside the right one on both sides?
Then you probably need to have a wall all the way up to the highest "ridge" at the end.
I have been thinking a little more about other types of constructions though, elevated wall life, etc., but haven't drawn anything yet..

Yes, that's what I meant, but I didn't think of a new "syll", you should be able to place the posts next to the roof beams...

But as I said, I don't know how those houses are usually built... I was just trying to convey my spontaneous thought construction. You should hope that more people respond, or ask a specific question in a new thread, then you'll probably get more people reading/responding.

Ok, yes, that sounds like a smooth solution Sometimes it's a bit difficult to imagine all the angles and corners in 2D, might actually need a 3D program to learn to draw in order to rotate and see, probably a requirement if you want to do it well, with the garage I didn't really have any plans at all, but it turned out the way it did too, not perfect but actually good enough so you have to be satisfied with that, I had a much more serious drawing for my "friggebod", in 2D though..
Unfortunately, I don't have time to sit and learn a new program or to draw for that matter
