Atlas Introduces First Ozone-Safe Polyiso Foam

Atlas Roofing Corporation has become the first North American manufacturer of polyisocyanurate foam insulation (polyiso) to introduce a totally ozone-safe product. In February of this year, the company announced its shift from HCFC-141b to pentane as the blowing agent.

The first hydrocarbon-blown polyiso, called AC Ultra™, is coming from a prototype production line at their Mesa, Arizona plant. Limited production of this foam has been occurring for about a year, according to Marketing Services Manager Rick Gelatka. Conversion of the second plant, in LaGrange, Georgia, should be completed during the third quarter of 1998. Total conversion of the company’s 13 manufacturing facilities should be completed in about three years, well ahead of the mandated January 1, 2003 date for phaseout of HCFC-141b.
