How much did it cost per pack?The material I used was Bradfords Supertel... It looks exactly like the photo of the 703 material in the thread above..
It comes in 1200x2400 sheets and is a semi-rigid fibreglass.
I bought the 2" thick, and covered the front wall corners with 2 layers...
This stuff is very effective as a bass trap..
It came as an individually wrapped sheet, direct from Bradfords.. I don't think it comes in packs.How much did it cost per pack?
If it's cheaper it looks like it could be the go.
Using Bob Golds Coefficient site:
Glasswool Supertel 50mm kg/m3 0.27 0.75 1.12 1.12 1.07 1.04 1.03 1.01
Insulco Semi Rigid IB (nil) 50mm 0.41 0.84 1.02 1.25 1.22 1.16 1.10
Insulco seems to do slightly better down low.
