P, Yes, use material that has a density of at least 2 lbs / cu. ft. Make sure you wear a mask when working with this material. It is toxic.  

Dennis Foley said
M, You can use 200 kg / m3. Metal boards will work. make sure perforations are min. 6 mm on 25 mm centers.  

Hi Dennis, can you please clarify what density to use? The specified densities are not the same, 2 lb/ft3 to kg/m3 = 32.03693 kg/m3.

Hi Dennis – I just wanted to check if you have any other shipping options for your acoustic foam . I’m in Australia and the distance and our weak dollar isn’t helping! Thanks ~ Mark

I was looking the the 25 x 18.5 x 2 [USD $97]… but I just realised that I am in the process of making 2 BDA‘s, so I would need 2 packs… which may not be feasible…
