intarnal walls concrete vs plaster

Hey guys. Im planning on building internal walls in a small factory dividing it into 6 rooms that I would like to be able to have bands rehearse in, obviously without too much spill between rooms. I was originally looking at building conventional plaster, wood frame walls with acoustic baffling but I have since come across the light wait concrete method of construction. As in the link below... http://www.formcraft.com.au/default.asp Has any one got first hand knowledge of this product or maybe some pro's \ con's that you could offer?? Any help would be great! Cheers.

There is an announcement at the top of the forum about what to do to assure getting as many responses as possible. The announcement leads to this post (click here). Actually, several people, who are experts on this forum, will not reply if you don't do what is written in that post. Many others who are very helpful, will not reply out of respect for the moderators' wishes.

Smells like three day old spam...
