Lower the ceiling with steel profiles, what material is needed?

[toker78]

We are going to install LED spotlights in the ceilings throughout the apartment and therefore need to lower the interior ceilings. But we want to lower it as little as possible. This is partly because of vents that are located high up on the wall. If we lower the ceiling so that it comes below the vents, the ceiling will be too low.

What different components are needed to lower the ceiling, joists, fittings, etc.?

Are steel studs needed? Otherwise, 28 spacing panel and gypsum. Building only 28+13, there are also spotlights that can handle this depth.

Hat profiles come in different dimensions, or secondary profile as it is also known. The most common is 25mm.

A tip is to check Gyproc's website; there are videos there on how to do it. Then you can buy cheaper materials than the original Gyproc.

Are steel studs needed? Otherwise 28 glespanel and gypsum. It only builds 28+13 and there are also spotlights that can handle this depth.

Borrowing the thread. Do you mean that you can screw the glespanel directly into the ceiling? Or should there be a gap between the ceiling and the glespanel?

Borrowing the thread. You mean you can screw the sparse panel directly to the ceiling? Or should there be space between the ceiling and the sparse panel?

It depends on what space the fixtures need and what the ceiling consists of.

If it is sufficient for the fixture in terms of space, then can it be screwed directly into the ceiling? That is, without any air between the sparse paneling and the ceiling. How does it work with the cables then? You would need to drill holes in the paneling for the cabling so that you can access the outlet since there is no space between the paneling and the ceiling? I hope you understand what I mean.

If that is enough for the fixture in terms of space. Then can one screw directly into the ceiling? That is, without any air between the furring strip and the ceiling. What about the cables then? You would have to drill holes in the panel for the cabling so you can reach the outlet since there's no space between the panel and the ceiling? I hope you understand what I mean.

You can refrain from having entire lengths of furring strip, leave a gap of 5cm so you can run all conduit/cable in that space. As long as you don't join a board within 10cm from the gap, it won't be noticeable.

It is recommended to use CC60 for 120 boards, and cc45 for 90 boards.
and use 13mm gypsum, not 6mm renovation gypsum which will just hang down.

I understand then. Thank you.
