any good on line retailers you could suggest? i know i cant test though
will look on the yellow pages for material retailer i suppose

Most of the manufacturers specify this so it's gotta work. I helped a friend do his home studio over the weekend and sent him off for cloth today and understand he ended up with muslin sheets. Havent checked them out yet but he assures me he can blow through them.

from what iv read all the suggested material allow fair amounts of air to flow but Guilford of Maine is described as

"Guilford of Maine Fabric is a 100% polyester fabric that are acoustically sound transparent. "

what it means im not quite sure?

[TrevCircleStudios]

It means it doesnt stop any frequency going through.

[sureno]

so may not actually be that relevant in covering an absorber, i would imagine if a material where to absorb sound, it would be the higher frequencies due to its structure and weight.

at the moment im finding it almost impossible to source any of this stuff in the UK, so may be left with no other option then to choose a similar material.

am i over thinking this all

this sort of material may be of some use:

http://cgi.ebay.co.uk/2m-BLACK-In-Ca...1%7C240%3A1318

the only example I can find at the moment so that exact material in the ebay listing may not be of any use??, but the material that is used to cover parcel shelves and boots ect is pretty good, I once had a car that had a straight through exhuast and the noise that came from it in to the boot was that loud it took over my back speakers!! (and no im not a boy racer..lol)
I had the boot and shelf covered with the car accoustic material and it made a HUGE difference, granted its a little expensive for material but it certainly absorbs a lot of frequencys and you can buy it in loads of different colours!

this thread should be a sticky its got some great info and the little how to frame pic will be useful to a lot of people!

In this particular instance, this is exactly the wrong sort of material. In the case of absorbers and bass traps, you want the rockwool filling to do the job of attenuating the sound waves. That being the case, the covering material must be as acoustically transparent as possible. Any material, such as this, that is designed to baffle any incoming soundwaves is therefor the opposite of what is required.
