Building a studio in a concrete basement - need some advices
Posted: Tue Sep 13, 2016 8:31 am
Dear all,
I will build a control room in my house’s basement in Switzerland. I would really appreciate your advices and experience here
I’m reading Philip Newell and Rod Gervais’ books and find a lot of inspiration here (thanks to J. Sayers and Soundman2020) and from J. H. Brandt studio designs.
Here are the room’s dimensions:
Length =499.0 cm - Width =472.0 cm - Height =400.0 cm
Concrete floor and walls, but not the ceiling.
The idea is to build a room within a room. I’m mostly concerned with the sound transmission to the ceiling as there’s a room up there.
In the current plan, the studs are made of 4x6cm lumber and will hold 5cm thick rock wool (60kg/m3).
The ceiling will “sit” on the inner leaf studs/wall.
I plan to use 2x15mm plasterboard sheets for the inner partition and the ceiling. There will be 15cm of air gap (including the 5cm rock wool) between the inner partition and the concrete walls.
I will then build a wooden structure that will hold 14cm thick rock wool (60kg/m3) leaving an air gap of 15cm from the plasterboard walls (for broadband absorption).
In the corners, there will be some superchunks bass traps.
A portion of the side walls and ceiling will be angled.
I have some doubts/questions:
1. Will the 4x6cm lumbers be strong enough to support the ceiling or should I use 6x8cm or 6x10?
2. For the insulation, should I use thicker rockwool? (10cm rockwool / 5cm air gap?)
3. Are 2x15mm plasterboard walls too thick?
4. Should I use some WIC Sway Braces to hold the inner structure? If yes how many and which type? (Should I consider the ceiling’s weight in my calculation?)
5. Do you see anything wrong or that could be enhanced? Please feel free to criticize
Here are some pics and the skp file (still work in progress) for more details about the project.
