Can't find the studs in the wall

[Mhenk]

Hi,

I need your help. I'm currently renovating one of the bedrooms and installing drywall, but when I got to the wall that is against the outer wall, I can't find any studs. The house is from '81 with a wooden facade.

The interior wall has a layer of drywall, then some harder foam, and then insulation. I've tried screwing all the way from one corner to the window and only found two studs, one about 5 cm from the window and one stud in the corner. Between the corner and the window, it's about 133 cm, and between the stud in the corner and the stud by the window, it's about 125 cm. But no stud between these. I've tried screwing all the way between the window and corner without finding any stud.

The walls I've screwed which are interior walls have been on 60 cm centers, and I could mount 120 cm boards without problem there.

Do you have any tips? Why can't I find any studs in the outer wall with 60 cm or 45 cm centers?

The joints on the panels should be visible down by the floor or up by the ceiling.

the seams of the boards should be visible near the floor or at the ceiling

have checked and found where the boards have been joined but when I test screw there, the screw doesn't hold. The screw is 41 mm long and holds if I test screw in the corner or by the window.

if it is a house made in a factory, it could be pre-made wall sections that have been assembled, and then some of them had both vertical and horizontal studs in the wall sections

if it is a house made in a factory, it might be pre-made wall pieces that have been assembled, and then some parts would have both vertical and horizontal studs in the wall sections.

I guess you have to search with a stud finder to locate the studs in this case? I made a small hole in the drywall seam and it's completely hollow right there.

Neodymium magnets are awesome. Easily find all the drywall screws with these.
