#703 fiberglass board in the UK?

I'm looking at putting together some bass traps and it seems that the thing to use is Owens Corning 703 fiberglass board stuff.

I've been trying to get my hands on some but it doesn't seem to exist anywere in the UK.

Apparently there is a soemthing called a Crown Universal Slab CS48 (same density) but it's not rigid.

Does anyone know where I can get my hands on that magic 703 sound (or lack of), or am I better off going with Rockwool? (If so anyone got any good designs for Rockwall based broadband 60-300Hz Bass traps)

Cheers,

Port,

Look for rigid rock wool and rigid mineral wool. Those are equivalent to Owens-Corning rigid fiberglass. Some brands to look for are Knauf and Roxul.

Also see the Acoustics FAQ, second in the list on my Articles page:

Superb, thanks Ethan

- it's your design that I'm planning to use. That link is really useful, definitely fills in a load of gaps.


As you can probably guess I'm a muso who's a newcomer to the home studio fraternirty and I'm mostly in bewildered awe of the jargon/complexity of acoustics. Your help is massively appreciated.

Hi Ethan
Just wanted to say nice site and thanks for the effort.

Indeed -

Sorry to labour the point but after some further research it seems my choices are limited to Rockwool RW3 (50mm 60 Kg/cu.m) or Rockwool RWA45 (30mm 45 Kg/cu.m)

Could I get your opinion on which would be the best product to use in Ethans Better Bass Traps???

Much effusive thanks again, only this time presumptiously in advance...

Port,

Either will work fine. I've used 703 which is 45 Kg per cubic meter. So I know that will work, and it's probably a little cheaper than the denser type too.

thats pretty much what I figured - thanks Ethan, the construction begins this weekend!
