acoustic foam is this the right stuff ?

I'm looking to buy acoustic foam for my new vocal room, i've look at auralex but the price is a bit steep, so after some reserch i found a manufacturer who make acoustic foam to order at half the price i,m looking at 600mm x 600mm by 50mm deep wedge cut they have sent me a sample and some tech spec but i'm not 100% sure this right for studio use . if anyone can help me i have attched the spec from the foam manufacturer. i wolud be gratful for any feedback regards greeny :D

it seems to have ok specs. but... it might be wise to ask them for more information - such as "what type of foam is it?" Auralex uses a more expensive formulation than many cheaper types of products...

thanks glenn for taking the time to look over the spec i will ask more questions :D rgards greeny

Hello Greeny, As you live in the United Kingdom you might want to try Dunlop Foams or indeed Tontine, they come under the Company "United-Bonded" and apart from Polyester such as Acoustisorb (Like a Semi Rigid 703 Fibre Glass though better specs) or AA-29/AA30 Density-30Kg/m3 Convoluted Foam that is Fire retardent and they will sell through a Pro Forma Invoice direct; so be clever and buy enough that you need then sell the rest you don't want on Eslay! Or double the width of the foam you put up! I.E 2 Inch/4 Inch (They will sell Directly to you - though you need the "Full" gusto to call up and order the same amount as you would from Auralex, and the quality is the same from what I can remember) I once grabbed 14.8Sq metres plus for $280.00 $AUD (Yeah.... Our Dollar has hit the floor now .... Anyone for Coal?) Cheers - Thought I'd pipe up even though an old postjavascript:emoticon(':idea:')
