Most effective bass trap

I have searched and read a lot on bass traps the last days.
Now I have a couple of small questions

I can buy some cheap heat insulation that have 18 kg/m3 density. There is no info on the air flow resistance. Do anyone know what it is likely to be?

In my research it seems to me that it is more effective with really thick low density superchunks then typical thinner owens corning 703(for corner bass traps). Is this correct?
How thick should I make the traps if the density is 18 kg/m3(posted a pic)?
Can I even buy them in the plastic tube and set them up like that or is that much less effective?
Space is no issue since I`m moving into a large space soon.

Hoping someone can help me with answers.

Thank you so much!

Are there any calculators(I`m on a mac) that you can plot in density, air flow resistance, thickness etc that will show the level of absorption?

Sorry for the noob questions but I am fairly new to this.

Peace

Yes, you can just stack them floor to ceiling in all corners. Looks a bit ghetto but does work fine. And yes they do have to be pretty thick to work on the low end.

There are two, the whealy porous absorber calculator and the other is a website that I think is in the sticky. Note that these models usually give single-incidence absorption, which is not directly comparable to the usual random-incidence test values you will find for devices and materials per the standard lab test.
