4x8 DIY treatments for Music Venue

My buddy just opened a music venue and he wants to treat the ceilings and above the music stage. He did professional treatments for the walls but given that it’s a large concrete venue and the out of site ceiling we are thinking about doing 4x8 treatments with large panels of OC 703 and hanging the frames via chain to hooks in the ceiling.

Any real risks with using 2x4’s if I use 6 or 8 chains to hold them up? What should I use to hold in the OC 703? I think we’ll wrap them in black burlap.

Thoughts?

Don't see a problem as long as they're anchored properly. This is what I did for my ceiling treatments. I also used Roxul Rockboard 60 because it's much nicer to work with than glass.


I used #8 eye hooks. They were 2.5" long, 1.5" of straight part. Straight into the studs.

Maybe use mounting wires instead of chains if you're going to suspend...

french cleat on top, thick layer of felt or something on the bottom for when the walls move Super easy to remove. Some of the treatments like the ones to the sides of the screen were made to fit exactly into the window frames

Given the cost and lack of OC 703 in my area I think I’m going to go win Denim. That’s what I used for my treatments at home and I really liked them!

Plus the cost differential is better given how many 4x8’s we’re constructing

what about roxul 60? You should be able to get either from a local supplier

First thought, commercial venue, burlap wrapped ceiling panels, what could go wrong? You need/should meet fire codes and I doubt that untreated burlap on the ceiling will be allowed. Even treated burlap is an issue since it must be re-treated every so often.

I have a large non commercial venue that does not need to meet strict fire codes and all of the fabric used for curtains, screen, panel coverings is IFR (inherently fire resistant) with NFPA 701 certificates. I am building 4x8 panels made with 4" OC703 wrapped in black IFR spandex (120" about $10/yd). I'm using 3/4 osb ripped to 4" for the outside frame along with edge and center retaining strips to hold it all in place. Corners and midpoints are blocked with 2x4s and used as anchor points.

I hate to be the party pooper, but does anyone remember the nighclub fire when Great White used pyrotechnics that ignited foam?

Rockwool is a good choice, though I'd suggest against using wood or flammable coverings in constructing something for a commercial venue.

Ask your doctor if DIY is right for you. Side effects of DIY may include anxiety, elevated blood pressure, lightheadedness, rapid heartbeat, skeletal muscle flaccidity, euphoria, psychological dependence, insomnia, confusion, blurred vision, implusivity, uncontrolled or repeated movements.

The best bet is to check with your building code department and fire inspector. Keep in mind that your insurance will also have issue with non approved items. Other gotchas include most any led light off of ebay. Most of the cheap led lights listed on ebay are not UL listed. Your insurance and fire code will insist on UL listed fixtures. What appear to be the very same lights can be found UL listed at a higher price. Basically, somebody paid to have them tested and is assuming some bit of liability in exchange for a higher price.

If it were me, and building code and the fire inspector agreed. I'd use Rockwool covered in an IFR fabric with either a wood or metal frame. In my case the whole building is sheathed in OSB so I'm not any worse off using OSB for the frames. For commercial I really don't know if wood frames are allowed.

Thanks for the advice! I’ll look into a metal frame. I think the denim insulation is fire rated.

i used 10' metal studs from lowes, instead of wood, because i didn't have a table saw... about 3.5" wide, use tin snips and rivets to put it together, and a commercial hot glue gun($50 or so) to attach the fabric to the metal... spray glue to attach thin butcher type paper to the front of the rockwool, if you want to attenuate just the bass frequencies, and reflect the higher frequencies back into the room.

maybe not as rigid as wood, but it won't burn.
