English Project Manager Re: Converter Gas A--id Plant Insulation Dear Sir Under paragraph titles, Pipe Insulation, we believe that you should delete the following - "metal reinforced fiberglas blanket" and insert "lt8 series KF Pipe Insulation, etc". As we talked on July 13, 1972, the 2" fiberglas insulation for all flue insulation should be flat 2" fiberglas insulation, 3 lb. density, applied over 10 ga. studs, a coating of insulating cement, weatherproof, breather type mastic reinforced with poultry netting. All stiffners to be insulated. If this meets with your approval I will include this in the bid package. Very truly yours, HEW/jm 'H. E. Wickes Project Manager
