Hi,

I've read a lot of threads about home theaters in basements.

Now, I'm an amateur when it comes to home theaters and would need advice on the interior walls in the basement.

Right now, there is framed drywall on the concrete walls, and I want to make new walls but will have big problems if I have to tear down the existing drywall with pipes, etc.

I have no issues with moisture.

Can I frame the existing drywall in some way and insulate in between to get a decent result?

Frame and insulate between the drywall sheets?

The reason I want to make new interior walls is that I need to install new electrical wiring in the whole room and want everything embedded.

The floor will be a carpet over the existing tiles, and the ceiling will be an acoustic ceiling (sombra).

The walls are what I need to solve before I can start...
 
It's probably not a good idea to lay carpet directly on tiles in a basement. I think you need to use some kind of ventilated underlayer. Moisture is always present in basements, even if you don't have problems with it.
 
Is the main purpose to achieve built-in electricity, or to get better sound absorption (I assume so since you refer to a home theater room)? If you don't care about the sound aspect, you can just put up furring strips and drywall again. No problems with radiators or other fixed installations on existing walls? Furring strips complicate things around windows and doors. If the main purpose is indeed the sound aspect, the best and simplest solution is to place some acoustic panels directly on the existing wall.
 
A breathable carpet should work on existing tiles, right?

The purpose is to embed all the electrical wiring and a wall to enclose all the cables to the media center.

I have a fixed radiator on the wall that I plan to frame around so it becomes "embedded" in the wall and possibly put something that conceals it a bit but still allows heat to pass through.

Thanks for the response
 
Carpet works excellently on tiles in the basement.

Why is there a problem with pipes if you are going to tear down existing drywall?
 
The main reason is because I want to build in pipes and radiators that are on that plasterboard wall, but of course it would be possible to tear it down and reroute the pipes.
 
Are you going to have a projector? In that case, paint dark (black), and aim for 100% blackout.
Then pipes and radiators won't be a problem, as they won't be visible. :)
 
Yes, exactly!
But I won't be able to tear down that wall without tearing down a bunch of pipes.
I'll have to try and see where it leads, I don't want to tear down when it gets cold as I need to empty the entire house's heating system and have old pipes, and you never know how it ends when you start with them :)
 
Are the pipes exposed today?
What prevents you from cutting just enough into the plaster so you can access and run the electrical wiring behind it, then plaster, spackle, and repaint it?
 
Yes, that is an option, but since the walls are just studded and drywalled (no insulation), I was wondering how the sound would be in that room...
 
Unscrew the drywall, insulate, and go with double layers of drywall is my thought.
 
Torn down the walls now. Planning to frame with metal studs since it's a basement.
But insulation shouldn't be against the exterior wall in a basement?
Smartest way to solve it?

Regards
 
Hello!
Are you looking to control sound insulation or room acoustics, or both?

If it’s only room acoustics you're concerned with, you shouldn't use gypsum boards at all. In a small room, you'll need plenty of bass absorption, so you need to build acoustic walls (as deep as possible, especially the front wall) either fully fabric-covered or with slat panels if you don't want a completely dead room and want to retain the energy in the higher frequencies. Regardless of the design, you build these walls with wooden studs. In a basement, you can advantageously use metal studs.
 
Hello and thank you for the response!

I just want to make the room a decent home theater for an average person. I'm not an audio expert but I don't want the room to sound boxy since it's a basement.

The ceiling will be sombra.
So a budget-friendly suggestion for the design of the interior walls.
It doesn't need to be soundproofed for the sake of other rooms.
 
Is there a Wall panel in black from the same manufacturer as sombran. It is a wall panel in equivalent material as the sombra ceiling. However, it costs a bit, but it will be so quiet that you will hear your own heartbeat if you put it on all the walls. Then you can cut out for electricity and pipes behind. It will become pitch black.
