Two Chicago-area curtain-wall system suppliers are trading lawsuits amid an intensifying dispute. The latest suit filed by Reflection Window and Glass alleges Kurt LeVan, owner of competing companies, made false advertising claims—violating Illinois law on consumer fraud and deceptive trade practices. 

The latest lawsuit was filed in July in federal court in Chicago by Reflection against LeVan and Talon Wall Holdings, Chicago Heights Glass Group and Entekk Group, three companies owned by him. The suit alleges that “LeVan companies and Talon Wall licensees marketed, promoted and sold Talon Wall to over a dozen occupied high-rise buildings in Chicago, New York, Denver and elsewhere with no fire protective material whatsoever installed in the curtain-wall fire gap.”
