Tontine ACOUSTI-PANEL - HP? New Tontine product?

Hey chaps! I have done a search but couldn't find any answers. I've been chasing some Acoustisorb3 for the start of a new year project, but along the way I discovered Tontine Acousti-Panel -HP. It appears to be a semi-rigid polyester panel. Is it comparable to acoustisorb 3 for constructing acoustic wall hanging panels at points of first reflection? There is no info about the density of it. http://www.tontineinsulation.com.au/fil ... %20'10.pdf http://www.soundblock.com.au/pdf/tontin ... sorb_3.pdf

Acoustipanel is slightly better than acoustisorb_3. Both in the 50mm version will serve you well. cheers john
