Hole saw in sparse for spotlights?

[MackanM]

Hello

Since we will have spotlights across the entire first floor and I'm the one doing it, I'm wondering:

When I drill with a hole saw for the spotlight and hit a strip, and then continue drilling the hole to place the spotlight there.
-Is this normal?
-Will this make the ceiling sag?
-Should the spotlight always be outside the strip in the cavity?

I can't find any guide on how to install spotlights.

I've attached a picture to show what I mean.

Red is the strip
White is the ceiling joist

Looking at row 3 from the top, all the spotlights end up in the middle of a strip.
The spotlights are fine with 3 mm when the plasterboard is up.

I would say without being 100% sure that you should relate to the cavities and not drill in the glesen.

Agree 100%!

Looking at row 3 from above, all the spots end up in the middle of a gles
the spots manage with 3 mm when the plasterboard is up.

But is this just one room, living room?
The glespanel is usually set with c-c 300 mm. And rafters/floor joists with c-c 1200/600 mm.
Then the sketch corresponds to a room about 10 x 6 m, 60 square meters.
And the number of spotlights is 110.
Is it just a theoretical consideration, or does it have any real-life connection?

But as said, do not drill/saw through the glespanelen!

Hello

It's a rough sketch of the entire house.
The living room incl. kitchen and dining area is

b4.6xL12.6 m

Which is more correct?
1. Install sparse paneling and set spotlights
2. Cc300 and where the spotlights should be, place sparse paneling next to it. The drywall will, however, hang in the air where they meet
3. Move the spotlights to the empty space

How is it done correctly? Or how does the carpenter do it?

If you use plaster in the ceiling, c/c 400 is sufficient with 1200mm panels and 450c/c with 900 mm panels.

Place an extra gles on the side where the spotlights will be, it's not that tricky.

I put a full, 3 rows of gles closest to the outer wall so I had something to screw the curtain rails into.

Will use 1200 to reduce joints.

If I place the studs on each side of the spotlight BUT! The drywall sheets meet in the middle between the glass panels where the spotlight is. Won't it crack or get different height differences due to movement from the second floor?
This will be a new build so hopefully, I can show you the result later.

400 cc will fluctuate over time, they say?

But how large are the holes? If they're like 28-30, it probably won't matter if you drill into the glesen, except that it's disgusting to deal with.

 

[MackanM]

The hole is 83 mm.

If you use plasterboard in the ceiling, c/c 400 is sufficient with 1200mm panels and 450c/c with 900mm panels

This is wrong. c/c 400Mm max is the standard, so for 900mm plaster, c/c 300mm is customary.

Will be using 1200 to reduce seams.

If I place the battens on each side of the spotlight BUT! The plasterboards meet in the middle between the glass plates where the spotlight is. Won't this crack or get different height differences due to movement from the second floor?
This will be a new build so hope to be able to show you the results later

I just did this in our den/our new bedroom. I don’t know how a carpenter would do it but I placed a batten on each side of the spotlight on top of both battens on the sides of where I wanted the spotlight and then I cut off the little piece where the spotlight would be.

In some places, I couldn't do that, but since our spotlights only built like plaster and half a batten, I took and placed a piece of batten on top of the one that was in the way and secured it properly on both sides, then cut away a piece where the spotlight ended up so it held the battens together above so they wouldn't flex.

That still sounds good! What size discs did you use and what was the spacing?

I just did this in our den/our new bedroom. I don't know how a carpenter would do it, but I placed a strip on each side of the spot on top of both strips on the sides where I wanted the spot and then I cut off the small piece where the spot would be.

In some places I couldn't do that but since our spots only extended as much as plaster and half a strip, I placed a piece of strip on top of the one that was in the way and secured it properly on both sides, then I cut away a bit where the spot landed, so it held the strips above together to prevent sagging.

That still sounds good! What size did you use for the boards and spacing cc?

I used short planks with dimensions of 600x1200mm and beveled edges.
I ran the spacing at cc300.

You'll need pots for the spots, then place them in the right spot first. Besides, I don't recommend having spots everywhere in straight patterns; it gives too much of an office feel. I placed spots 2 by 2 a little in front of the walls around the rooms. This way, the walls are illuminated, which gives the most sense of light. Spots in the middle of the rooms might only shine on the floors.
