Hello,
I’m building some acoustic panels, they will be around 1,35 meters by 0,6 meters.

Inside the panel I will be using 2 layers if 40mm high density Rockwool and also 1 layer of 40mm Low density rockwool, so a sandwich of 3 layers total but with different densities. (it’s the material I have)

My question is,
Should I put the low density layer up front the other 2 high density layers, or should I put the Low density layer on the back (wall side) having the 2 high density layers up front?

I had different opinions on this, so I would like your help

Thank you so much for your help

We do not use this material type due to the health issues along with poor acoustical performance.
