Rockwool - RWA45 VS Sound Insulation Slab

[marty3]

I have just insulated a stud wall with Rockwool Sound Insulation Slab

Now I need smore more for the rest of the walls I have noticed that Rockwool RWA45 is about half the price and looks to be the same product.

I have been trough the datasheets for both products but haven't been able to work out if there is a significant difference between the m.

Does anybody know?

Those two links show two very similar products but the pack sizes are different hence the price difference

The pack which is £20 still works out a little cheaper but not half the price
