Hi,
Our "Danosa" product arrived today
http://portal.danosa.com/danosa/CMSServ ... g=1&site=1
- it is actually Rockwool with a Danosa label on!
As can be seen from Rockwool Spain site:

You can't seem to get RW3 here, so compared specs. They may be useful to someone?

The "Danosa" (Spanish rockwool) product is definitely flexible and leaves us wondering if it will actually stay on the wall...
By the way it's €7.84 m2 plus IVA
