Sebago, Inc., et al. v. Beazer East, Inc. was a suit on behalf of owners of commercial buildings with corrosive phenolic foam roof insulation, alleging, among other thing, failure to disclose known defects in the insulation products.  The case resulted in a significant decision upholding RICO claims against the manufacturers.  See Sebago, Inc. v. Beazer East, Inc., 18 F. Supp. 2d 70 (D.Mass. 1998).  The case also resulted in court-approved nationwide class settlements with the two manufacturers of the phenolic foam insulation, worth a combined estimated value in excess of $100 million.
