Hello,

I've been browsing the forum since we became homeowners a little over a year ago and have been helped countless times. Now it's time to ask some questions of my own that I hope your wisdom can answer.

I'm going to furnish our insulated upper floor. I'll start by making an installation wall on the long side to be able to run the prepared radiator pipes so they come under the skylights (instead of the interior walls of the bedrooms...). I'm thinking of doing this with 45x45 studs and then applying single plasterboard. My question is how I should stud. Can I do it with horizontal studs (what spacing in that case?) or do they need to be vertical (do I need top and bottom plates there as well?).
Attached is a picture of the wall, which is 1m high.

Attic under construction with wooden beams, a plywood floor, and tools including a shovel and broom. Slanted ceiling with skylight in background.

I will also create a joist over the two bedrooms to be built to make some storage space. The trusses are on cc1200 (hastily measured with a moderately amused daughter on my hip) and it feels most natural to attach the joist to these. Is 45x170 on cc1200 with noggings between sufficient, or should it be dimensioned differently?
Can it be open at the top of the storage space between the bedrooms, or does the interior wall need to be studded all the way up to the roof? I imagine it should be possible to screw up a beam between the load-bearing column (115x180) and the outer wall that the joists can rest on and attach the studs to?
If it can be open, the width of the space will be 3.7m and the depth 3.9m.
Attached is a picture of how it currently looks if that makes any of what I wrote clearer.

Interior of an unfinished attic with narrow windows, wooden beams, a tripod, and construction materials on one side, with slanted ceiling insulation.

Have a nice weekend!

Why not install underfloor heating and get rid of the radiators?

I'm going to furnish our insulated upper floor. I will start by making an installation wall on the long side to draw the prepared element pipes so they come under the skylights (instead of the inner walls to the bedrooms...). I plan to do this with 45x45 studs and then cover with single plasterboard. My question is how I should frame. Can I do it with horizontal studs (what distance in that case?) or does it need to be vertical (top and bottom plates too then?).

Is 45x170 at cc1200 with noggins in between sufficient or should it be dimensioned differently?
Can it be open up on the storage space between the bedrooms or does the inner wall need to be framed all the way up to the ceiling? I'm thinking that it should be possible to screw an anchor line between the load-bearing post (115x180) and the exterior wall for the joists to rest on and attach the studs to?
If it can be open, the width of the space will be 3.7m and the depth 3.9m.

Installation wall use plywood and plasterboard so everything can be screwed and hung easily
 
The installation wall is no longer a problem.
No ideas for the joists for the loft? The trusses are not dimensioned to bear the load of a storage loft, so I cannot use them. Should I dimension the interior walls so they become load-bearing instead? And can I then place them directly on the floor chipboard?
