Cheap 703 Equivalent - Chicago Area

[MightyM]

Fabrication Specialties (http://www.fabricationspecialties.com/) in Bridgeview IL has
Ottawa Fiber OFI48 (2") for $0.60 /sq.ft. They were able to give me 4'x4' panels, as well as 2'x4' panels.
Local delivery (Chicagoland area) was $25.

Compare this to an average cost of 2" 703 of $1.54 /sq.ft. (http://www.atsacoustics.com/item--Owens ... -1004.html)

The also carry other various fiberglass and mineral wool products.
