I'm in ontario canada, and owens corning says they do not sell it in canada.
OC has a great reputation for bad customer service. OC Canada is headquartered in Montreal. Try also OFI (Ottawa Fibre Inc), Knauf Canadian headquarteres in Richmond Hill, and Fibrex in Sarnia. Ask for 3lb/ft^3 glass or 4lb/ft^3 mineral insulation. Yes they are both mineral wool, but that is the industry norm in North America.
Also, try commercial insulation firms. They use this type of material all the time.
U can. Although there has been much discussion abut what is more critical in the case of the resonator design here, the fabric or the Insulation, but I believe in this case as it is a bass trap primarily, the Insul should be upagainst the fabric which is up against the slats.

Just thought of another question. Is there any harm in putting the bass traps and slot resonators on casters? One of the corners had a closet i need to get at, so rolling em outta the way would be ideal.
Contact Patric at Isofab in Montreal (they have offices in Toronto also) and they sell and stock OC 703, 705frk, Ottawa Fibre, Fibrex, Mansville, Roxul, and many other great isolation and insulation materials.
Tell them you are an acoustical contractor, pay cash, pick up the items yourself, and you will get up to 57% off Canadian list price!...
So, I'm about to make these badboys and I had another query. What happens if I don't make them the full height of the ceiling. In two corners I have a one foot by one foot box at the ceiling that goes around some vents.
