FROM: P. W. MAY CONSTRUCTION DIVISION
PROJECT 3315 - BEAUMONT - NEW METHANOL PLANT
Forwarded per our discussion are comparative insulation price taken from the most recent Armstrong contract in effect at Beaumont Construction, showing relative prices of unibestos and inhibited calcium silicate. We have also shown the increased cost of unibestos over inhibited calcium silicate.
Should you desire comparative data for other material siaes and thicknesses, please advise. Because of the added cost of unibestos, we favor the use of inhibited calcium silicate.
