Acoustic treatment

I just came across this old topic - http://www.bangingtunes.com/forum/topic/t29612/

I need to get some acoustic treatment for my room so this looks like it could be a good option

Does anyone know whats the best type of wool to use this mineral wool -

or this type of rockwool

and would this be a better option than say buying an auralex room kit or some foam tiles??

Anyone?????

Just want to know if this would be a better option than foam tiles and what type of wool to use

Cheers Ry

I take it i can get this from somewhere like b&q

Cheers for all the replies

Think ill go with this option
