1/4" thick Cork Panels on the walls/ceiling??

[illacov]

I have an opportunity to get my hands on either some 1/4" or 1/2" thick cork panels for cheap.

I have a pretty decent sized room, its a finished attic, its about 15 feet wide, 24 feet long and about 12 feet tall with an angled ceiling (like a roof).

I already have 12 panels of 2" OC703 wrapped in burlap in various places (mainly where instruments and vocals with gobos are tracked) which so far has worked to great effect in reducing reflections.

I wanted to use the cork panels, since I have read from various sources that using different kinds of absorption materials together in various places can offer better results rather than plastering the walls and ceiling with 2" or 4" thick OC703 panels.

I remember going to an attic party a few years back and the attic was finished with thick cork tiles (looked ready made, they had holes punched in them like some industrial ceiling tiles) on the ceiling. It was indeed a rather large attic space about twice and wide as mine and longer but the room was dead as a doornail. Like next to zero ambience.

I can get 288 square feet for under 200 bucks shipped.

if I go with the 1/2" thick cork I can get 144 square feet for under 230 shipped.

Any opinions on this??

By the same gesture for arguments sake, 2" OC703 costs 6 dollars for an 8 sq ft panel vs 1/4" cork costs $4.20 for a 6 sq foot or 1/2" cork costs $9 for 6 square ft.

Obviously the cork doesn't need covering since its fine "naked," so it costs less to treat regarding fabrics etc...It does need to sit out for a few days to settle to the room humidity etc but you can definitely cover alot of square footage with the 1/4" or 1/2" derivatives.

Any opinions? Expert or amateur?

People are always going with OC703 but I've wanted to try some cork for a few years now but Ive not seen much about it on GS, even multiple searches don't turn up much about cork on the walls except in old school studios.

So fire away!!

Short answer: cork is not an effective absorber for reflection points or most other places in a small room.

So does cork not work at all Ethan?

Why was it used so much to treat studios in the past??

I'm not trying to get a "dead" room by any means but Ive been to the attic in question when it was empty and still very very dead.

Please fill me in here. Thanks for chiming in.

Cork absorbs some, at some frequencies. But it's not a good broadband absorber. Most of the studios I've seen with cork are much larger than the typical home studio. Treatment strategies depend a lot on the size of the room!

Just do it, anything's better than having huge 703 slabs all over the place
