Please don't use bare Rockwool. There are other options! I personally started using Akotherm D40 (80mm), which is a really dense sort of polyesterwool.
Is this Basotect with best €/m2 price?

What makes Basotect special? I don't see polyester wool products differing much either. Of course density might vary by model.This is not Basotect, just regular melamin foam. Unless it says it's basotect it's not basotect.
polyester wool
I'm asking what makes melamin foam products different from each other? "Basotect" vs "T.akustik". There's not much difference on the polyester side either that I see.it's not wool it's foam, and it does the same job while having lower density than wool.
basically weight for absorption and better material to work with without protection.

Well.. yeah.. seems we are going in circles. There's also 40kg/m3 polyester wool too. And it's really more about the Air flow resistance and the correct density depends on how deep you are making it.density for absorption mostly. regular polyester foam doesn't absorb as much in low frequency because it's not dense enough like rookwool.
yep this is important, if the material is too dense for the air to penetrate then the difference between a 15 cm panel and 30cm would be very slim.regarding density = better,
it actualy depends on the thickness of the material.
what realy matter is the gas flow resistivity (which is related to the density, but varies when comparing 2 products with same density).
let's take this example: https://gearspace.com/board/showpost.php?p=7480592&postcount=33
the denser material is better with a 10cm panel, but with a 30cm panel the less dense material is much more superior: http://www.acousticmodelling.com/ml...d32=100&s41=2&d41=100&v41=12000&s42=1&d42=100

I think that's what makes Basotect so good, at 10cm it acts as if it has rockwool like density and at 30 cm its 9 kg/m3 shines through.
Basotect's flow resistivity is 12,4 kPa*s/m² incase you want to run similar simulations.afaiui the denser material becomes reflective at a certain thickness, making it the point where it becomes useless to add to it.
in this example there are baiscly no gains after 200mm: http://www.acousticmodelling.com/ml...d32=100&s41=2&d41=300&v41=15000&s42=1&d42=100

Basotect is mostly used because of its fire resistance. That said, its acoustic properties work really well.What makes Basotect special? I don't see polyester wool products differing much either. Of course density might vary by model.
