Help me decide

[cooker]

Finally I got to buy some fiberglass today. Problem was the store near me had only 2 type's, the fluffy roof type (forgot to check density) and something equal to 705 FRK:

İzocam - Yalıtımın Türkiye’deki Adı - Izopan

Its thin though, each 1.5 cm. I bought some but making enough traps from these will be a little too expensive for me (but by time I can manage if its worth it).

Question is if I place the fluffy fiberglass behind 1 or 2 of these in a frame, how thick must the traps be?

incase if it needs to be too thick, I saw Ethans tests on 3" 705 frk's and results seem good, is 3" a good balance with only 705?

My home studio is a nighmare: Small, has some furniture and a lot of corners...I'm not expecting any miracle's...

I would make them 6" or thicker.

For straddling corners you really want them to be 4" or thicker when using rigid fiberglass or mineral wool.
