Home Studio construction advise needed

[qwerty12]

Hi,
I have a basement 44 x 14 ft with 2 x 10 joists and subfloor above it. One half of the space has a 7 ft ceiling, the other half is crawl space with 6ft
ceiling. I would like to convert the 7ft ceiling half into a recording studio.

It has a 4 inch cement slab floor.

I would like advise please on what I should do about the cement slab floor. It is a radient heated cement floor. I have been thinking about two options;
1. Staining the cement and put an epoxy over top
2. Putting a wood floor overtop. Not sure how to do this and keep the radient heat floor so it will still efficiently heat the basement.

The walls are currently cement poured with wooden studs, pink insulation and vapour barrier over top. I have been thinking of two options for finishing the walls:
1. drywall
2. Wood panelling with tonge and groove pine.

What to do with the ceiling. Between the joists I have safe and sound insulation 12". I was thinking of strapping the joists with 1/2 wood strapping and drywall over it.

Do these options sound ok. I would like to prevent sound from getting through the ceiling. As the walls are cement poured and there are no windows in the basement and the basement is completely underground, I think my main consideration in keeping noise from getting out is properly insulating the ceiling and wall I will be putting up to the crawl space.

Some advise would be much appreciated. Thanks.

Tim

Tim,

Whatever you put on the ceiling will reduce your ceiling height. You have two options;
1. put 2 layers of fire-stop gypsum board between the floor joists up against the sub floor to add mass. Then fill the remaining space with fluffy insulation and cover the entire ceiling with fabric.
or
2. install resilient channel to the bottom of the floor joists, fill the cavity with fluffy insulation & drywall with 2 layers of fire-stop gypsum board.

The second option will give you more transmission loss (isolation) but with a lower ceiling. Without details on your current construction, I can not give you an isolation figure (STC). Green glue between the drywall layers will increase transmission loss up to 10db.

Drywall is more massive than paneling and therefore has better value for isolation. - just be sure to treat the walls acoustically, ie; traps, diffusion, etc... I would recommend the wood on the floor for aesthetic reasons. -Check the data on the flooring for use with under-floor heating.

Cheers,
John

Thanks for your response. A few questions.

What is fluffy insulation. What model, type is good.

What type of cloth are you referring to in option 1, should be placed over top of the joice. What procedure do you use to install the fluffy insulation. Put the cloth first and blow the insulation above it?

Thanks.
Tim

R13 is fine. The pink stuff is also fine.

Anything breathable. Guilford of Maine is nice, but expensive. Anything with a thread count under 200 will be fine.
