I am going to fill the void between my 2"x6" ceiling joists with rockwool, which is 5 1/2" deep.
I would like to cover the ceiling with an acoustic type fabric, that is as non-reflective/cost efficient as possible.

What are my options?


Thanks,


Rick

Check out ATS Acoustics (www.atsacoustics.com) There prices seem really good and there shipping is decent too. I just orderd there fabric color sample thing from them. This is where Im looking to get my stuff from. They also carry and ship OC703 and a house brand. Check out the DIY section on there site for the fabric.

fabricmate.com, GIKacoustics.com

You can order free samples of GOM fabrics at the Guiford of Maine web site, look for the sample center.

If fire rating is not a concern then you could go to your local fabric store and buy just about any fabric you can blow through.

rich121 I would be really interested in seeing a building thread for your theatre. Looking at the pic you have a older house. Crazy amount of sistering on you joist also. I bet that was a fun one.

The joist sistering was the easy part.
Previous to that, there was a wall/archway where the LVL beam is. I had to build a temporary wall on either side, the length of the room, remove the origional wall/archway, then cut the existing joists exactly where the new LVL beam was going to fit (only allowed 1/8" gap in joist hanger).
The origional joists are only 2"x6"x12' so they needed sistering to support the second floor. There were stress cracks in the old plaster from previous roof snow load.
After everything was cut, then, I had to rent 2 material lifts, one for each end of the 19' beam and install...lots of work!

But, the end result gave me one room instead of a livingroom and dining room joined by an archway.
Now, the hardest trick...make the $$ stretch enough to finish :)

Hello....

Anyone else have suggestions?

I would really appreciate any help can get, so let your knowledge flow.

Some good inexpensive acoustically non-reflective fabric suggestions would greatly be appreciated!

:)

Best way to go cheap is to look for a sale at a fabric store or on-line.

As a reference point the GOM is going to run about $1 sq ft. It comes 66 inches wide.

another site to check out is dazian

You also might want to consider landscabe weed block if you care for that look.

i am using black felt. $4 a yard.

and
i think that main beam is racist :D

Rich, this may not be a concern for you, but aren't you worried about sound traveling to the floor above you? If you don't drywall this floor, it will be very noisy above your theater. While everything is exposed and unfinished like this, you have an opportunity to really do a great job with a decoupled ceiling, etc. Then you could put acoustic treatments on the ceiling after you're done, but most people don't put treatments on the ceiling anyway, only on the side walls. Trust me as I am someone considering tearing out my existing dry wall ceiling just to properly decouple the ceiling. You can read about it on the threads on this forum and start at:

The only thing above my room is my daughters bedroom..which is thickly carpeted and she is quite quite there, other than when she is practicing her Viola...
Do I need to worry about dampening, isolation etc. if there is not a problem with sound coming from upstairs?

I am trying to learn this, and anything that members can tell me certainly will help.
I am doing this slowly, as I want to do it as best I can the 1st time, I don't have the funds to fix it later.

Again, I really appreciate all the great suggestions and tips.. keep them coming!

This one is on clearance. It comes 40 inches wide, so it would span 2 joist bays. 27 cents a square foot. One choice of color, natural canvas.

Will she be bothered by what music you play? Will she be able to sleep, to study etc. If you are only going to be playing light classical music while you read then your plan for open joists with insulation and fabric may be just fine.

In this forum we usually plan for an action drama sound tracks with explosions etc.

Yes, after talking to some others I think I will need to cover the ceiling, or just leave partial openings.
Others have concerns about making the room to "dead" sounding, which does makes sense.

I just want to do the best I can afford, I greatly appreciate your comments and help!
