Hello all!
Recently, I have been trying to figure out what insulation material is best to use for my first room treatment. After browsing/drooling over HomeRecording, Gearslutz, etc., I see that many use OC703, Roxul Safe 'n' Sound, or simply pink fluffy fiberglass insulation for larger bass traps. The room I'm going to be using is --you guessed it!-- my bedroom, which is 101.5" W x 159.5" L x 98" H (2.58m x 4.05m x 2.49m).
Since I cannot find OC703 in my area (called all the building-supplies stores around Bloomington, IN), I have narrowed my choices down to Roxul Safe 'n' Sound or John Mansville R-30 fiberglass insulation. I will be using the Safe 'n' Sound for first reflection points/bass traps/clouds, whereas the JM R-30 will be used for the superchunks. My current plan is as follows:
(4) Superchunks in each corner, using JM R-30
(2) Absorbers at first reflection points on L/R walls, using the SnS
(1-2) 6" acoustic clouds, one above mix position, the other in the back of the room
(4-6) 6" bass trap panels in wall-ceiling corners -- two in the L/R corners of mix position (hereinafter MP), one in corner in front of MP, possibly three in the rear wall-ceiling corners
Since it's a hard floor, I will probably through a rug under the mixing chair, to tame any highs if necessary.
Reasoning for my choices are 1) budget (the usual; the JM is much cheaper), and 2) because of the rough correlation between a material's density and its gas flow resistivity, which I believe affects an absorber's range of well... absorbtion.
Quoting Andre:
Density of the Roxul: 2.5 pcf (40kg/m3)
Density of the JM R-30: 0.5 to 0.8 pcf (8.01 to 12.8 kg/m3)
So will using the R-30 negatively affect the trap's performance in regard to using the SnS instead?
Maybe I should I just wait until getting a measurement microphone?
For some of you, these are probably some of the most redundant questions you get! But hey, I'm only in high school, and it's late here, so you just KNOW that I'm going to forget things! I also tend to overthink things...
Anyway, thanks for the help! Hope to hear from you!

Quoting Andre:
For BIG Bass Traps: (i.e. significant corner trapping)-- Use LESS DENSE material, i.e. Roxul 40 or Safe N Sound. 17" corner superchunks (24" facing) or 12" soffets -- or larger. Fully pack -- leave no airspace. The air already moves through the less dense material.
Density of the Roxul: 2.5 pcf (40kg/m3)
Density of the JM R-30: 0.5 to 0.8 pcf (8.01 to 12.8 kg/m3)
So will using the R-30 negatively affect the trap's performance in regard to using the SnS instead?
