Additional insulation - how to properly attach the framework for the windows?
I am in the process of adding insulation to one side of the house externally, which means I need to frame around the windows to move them out. Craftsmen put up frames and installed new windows on the other side last year, but now it's time to do at least the framing part myself.
Now to the question. I am doing it the same way as the craftsmen, building "boxes" (rectangles) of 45x145 that extend 145mm from the old wall studs. But... what is a good way to attach my boxes (that will carry the weight of the windows)? The wall consists of 45x145 so I am thinking that wood screws, e.g., 8x240 in an appropriate quantity might be suitable? If so, how many would be appropriate?
Attached is a picture of what it looked like on the first side when I had torn off the old panel, etc., it is built out with studs that were protected over the winter with wind protection fabric. The windows are located entirely outside the original wall construction.

Below and above you mean? For example, https://www.jula.se/catalog/bygg-och-farg/beslag/byggbeslag/vinkel-skarvjarn/vinkeljarn-340039/ ?G gusvo085 said:
What the craftsmen did is just screwed directly into the frame, but I didn't see how long the screws and how many, but they said they used many. It seems to hold like a rock anyway.
Now I have the studs in place and it turned out as shown in the picture. A stud underneath is screwed into the frame with 140mm screws. The "frame" where the window will sit is on the stud, and there are some reinforced angle brackets between the stud and the frame.
The frame is also screwed into the frame with 240mm screws (the frame is 145 deep) in at least 8 places (there were a few more on the other frames, there were three frames put in place).
I think this will hold, it feels stable at least.
The old windows remain inside the frames until it's time to install the new ones.

Bless you! How did it turn out then? Were you satisfied with this construction?
Did you consider so-called construction screws (for example https://www.essve.se/essvese/sv/pro...-87501-46/konstruktionsskruv-et-t-corrseal-46)??

I did three things:D danne_i_huset said:
• a beam under my new frame where the window will sit, the frame stands on the beam
• angle iron between the frame and the beam underneath
• the longest possible screw through the frame into what the windows previously sat in
It felt stable at least...
Attached is a picture of how it looked when I had made a window's frame. The old window is still inside until it's time to put the new one in place.
I now realize that I answered the same thing I wrote earlier, but the truth is that the new windows are not in place yet.
Insulation and new paneling are in place, but I don't want to install the windows myself, so I left it over the winter (covered with wind protection fabric), and some time ago when I had contacted the builder I used before, this corona thing came up, so right now the window installation is postponed for the future.
