K i decided on d i y traps this is the rockwool im gonna buy...

K so no owens corning in israel ,found these:

This is ROCK WOOL not fiber glass.

2" 120 cm on 60cm 60kg density (wich for some reason has a higher nrc then even 120 kg or 80 i dunno why). the nrc without distance from the wall is 0.72 and with 5 cm distance from the wall its 0.88.

the price for one board is approx 6.5$.

I need your guys ok before i can go on with buying ALOT of those....(approx 24 for 7 bass trap and 8 for reflection points)


P.s if the nrc is not that good please tell me (just cause its the best thing i found in israel doesn't mean ill buy it any way).


tHanks!

The density seems right for the application!

If it's the same assortment of rockwool down there as up here, you could try to get 5cm thickness or more instead. Makes it easier not having to stack the thin plates.

PS: love your avatar! That game was among the best back in the days!

My mind is slow today. 60kg/m^3 is the density used in the Rockwool brand "acoustic plates" that is the recommended tool for this purpose. (and I have hundreds of of kilograms of the stuff, so I should have thought of it before!)
