Can anybody suggest a vendor for coarse vermiculite in the Triangle area? I'd really like to find something in Durham, but so far all I've found is the little 8-qt (for $4!!) bags at Lowe's. That gets pricey when one sums up to 3 cubic ft!
Some of the other forums have had comments about loose fill attic insulation, but I can't even find that -- Lowe's, Home Depot nope...
