Floor or wall first?

[Hejm]

Hello,

I am planning to build a home theater room in my basement and I'm wondering about the best way to do it...

For the floor, I'm thinking of laying a Platon mat + chipboard + wall-to-wall carpet.

The walls will be air gap against the concrete wall + metal stud + insulation + plywood + gypsum.

Now I'm wondering if I should finish the floor first and set the studs (tracks) on top of the chipboard and thereby have the Platon mat over the entire floor, or should I erect the walls first and lay the Platon + chipboard out to the new interior walls?

I don't have any moisture problems in the basement today and would like to keep it that way...

I hope I’ve explained this in a sensible way...

Thank you in advance!

I would probably have done the walls first... but I would have replaced the plasterboard with fiberglass gypsum, or aquaboard... Alternatively, no framework, but built with thin leca blocks on the inside, then plastered and skim-coated for a good bond with paint or wallpaper...

I will look into fiberglass gypsum and aquaboard, thanks for the suggestions!

I suspect I will need a framework if I'm going to come up with something for the acoustics...

Why build with bathroom boards?? Then the wall can't "breathe" anymore.

Why build with bathroom panels?? Then the wall can no longer "breathe."

Aquapanels' big selling point is the absence of cardboard, meaning nothing that can mold. However, the panels are not diffusion-tight and should be moisture-proofed if installed on a wooden frame in a bathroom environment. Though, I agree it's a bit overkill with expensive Aquapanels in a cinema room.

Okay, then we'll skip aquaboards

Anyone else have any thoughts on floor or wall first in this construction?

I would place the govlet first... it's simpler and more stable. The wall studs will be made of metal and are not load-bearing, so there will be no weight that the 22mm chipboard floor cannot handle.

However, I would use chipboard instead of plywood = cheaper.

Then I would consider where to put "the stuff," like the TV, projector, etc., and maybe reinforce the walls there with wooden studs.

Lastly, work with studs and insulation; otherwise, you won't like the sound in the room.

Hope this helps a bit

Thank you very much for your input Danneå, feels like I'm on the right track then...what do you think about this picture I'm attaching?

Best regards,
Hejm

Would love to help but can't see what's on your image, the text is too small... Can you write with larger letters?

 

[byggare henke]

do the floor.
but maybe just have hanging fabric as walls?

 

[Hejm]

Danneå:

Oh, didn't think it would be so small

Yellow = insulation
Gray = metal studs
Blue = platon sheet
Brown = chipboard
Red = carpet
Black = acoustic ceiling

Thanks again!


Builder Henke:

Okay, another vote for that, feels like that part is solved

I'm planning to hang black fabric on the framed walls...

Thanks!

 

[Danneå]

Ok, then I'm with you.. Yes, I like it!

Just a small thing, the rug is sexy, but it gets very dirty.. just keep that in mind

Question about the walls: aren't you going to use any panels like particle board or gypsum, just hang black fabric there? If so, are you going to stretch it or just hang it up?

 

[Hejm]

Sounds good! I just can't go without wall-to-wall carpet, it's too comfortable

I'll be putting up chipboard + drywall on the walls, then black molton stage fabric...

Is there anything I still haven't thought of?

 

[Danneå]

I understand the carpet is nice
Where do you run the electricity in the walls? In the metal studs with the insulation? I think it looks best to run as much electricity as possible inside the walls

 

[Hejm]

Yeah, I was planning to run them through the steel studs, that would probably be best, right? Then I also have the option to run whatever I want above the acoustic ceiling, where there's about a 10cm air gap...there will be two speakers in the ceiling anyway...
