I'm going to hang a lamp in my wife's office, weight 2 kg. Our house is from 1967 and the ceiling (see picture) in this room is original (as far as I can tell). It feels sort of like treetex and I know from other rooms that it can hold almost nothing. I previously managed to drill and anchor two feather-light smoke detectors but don't dare to do more than that. Therefore, I had planned to find a stud but my stud finder which normally works like a charm (on walls) either indicates nothing or indicates inconsistently on the ceiling. There is an old-style box in the ceiling (i.e., the hook holds the cover and is screwed into the box) and it should hold up to 15 kg thus it must be screwed into some kind of stud/wood beam, i.e., somewhere there is something sturdy to screw into. The lamp itself has a bracket fastened with a total of four screws, so if I just find a suitable place to attach it, the weight shouldn't be an issue.
TL;DR: where can I drill so that I'm screwing into the framework holding up the ceiling panels? In the seams between the panels?
Above the seams (on the long side), there is a sparse panel to which the plates are attached, probably with so-called clips. The Tretex plates themselves do not hold much. Regarding the box, it is likely attached to a piece of sparse and lies across the other sparse in the ceiling. It seems to be between two sparse, as it would otherwise be difficult to fit the pipes into it.
Above the joints (on the long side), there is a sparse panel to which the boards are attached, probably with so-called clips. The Tretex boards themselves do not hold much. Regarding the box, it's probably attached to a piece of sparse and lies across the other spars in the ceiling. It looks to be between two spars, otherwise, it's difficult to fit the pipes into it.
So do the beams/sparse panel run inwards/outwards in the picture (i.e., along the boards) or left/right (i.e., across the boards)? Maybe a dumb question, but I want to be sure before I start drilling.
Why drill, you only do that if something heavy needs to be mounted. The Glesen is probably 28 mm and it's fine to drive a screw into it without it cracking. The plate is probably 12 -13 mm thick, a 25 mm screw will do fine.
Why drill, you only do that if you are putting up something heavy. The Glesen is probably 28 mm and it's fine to drive a screw in without it cracking. The board is probably 12-13 mm thick, a 25 mm screw will do just fine.
Ah, yes, no, it was probably just an old habit maybe. And of course, even if the wood in the glesen cracks, you won't see it. Didn't think of that.
