Sorry, a bit click-baity headline.
But the question is whether I should reinforce the load-bearing parts of my walls?
You see the picture. The roof is supported by 2 nailed together 28x58 (type) at a distance of 1220. At least in the part I have opened. Then there are slats in between to form compartments that were filled with wood shavings. Or well, they probably were in the 50s. Now 1/3 of the compartments are just air.
I guess that the "slats" also help support the whole thing. Above the window, it can be seen that the beam has sagged in the middle.
The roof beams are thicker, but I don't know the measurements yet, and have a span of 4 meters. And it can be seen that it sags in the middle.
The plan is to insulate with wood fiber boards, between the studs, and then add 45 mm insulation internally. And eventually 2x45 mm externally.
But what do I do with all these slats? Insert a standing stud between the 2 standing ones and then remove the horizontal studs?
I’m going to replace the windows. How can I relieve the load above the window?
