I believe it is better to use thicker lighter stuff than thinner denser stuff.
You'll probably have more luck with rockwool in the UK.

Ahh I see, so I would probably be better going for the 100mm thick 45kg/m3 rockwool then?.

At that lower density, could I even double that up, two slabs making it 200mm thick for corner traps?

Am I right in also thinking that, being a bass trap and not so much for broadband use, that it doesn't matter if the material is a bit thicker than normal? (concerned about the health side of things, dont want fibres escaping).
