Kingspan Insulation is the world's leading manufacturer of CFC/HCFC-free rigid phenolic and CFC/HCFC-free rigid urethane insulation. Kingspan Insulation is part of the larger Kingspan Group, which has operations in a range of product divisions including pre-insulated building panels, environmental technologies and renewable energy technologies.
GreenGuard, a division of Pactiv LLC, became part of Kingspan Insulation in 2014. GreenGuard products have been manufactured in the USA since 1982. GreenGuard products are green beyond the color. They help meet Green Building requirements to create healthier, more durable, and cost-efficient structures. The Group's primary activities in the us commenced in 1999, when Kingspan Corporation was established in Austin, Texas to facilitate the export of products. In 2001, Kingspan Group expanded its North American operations through the acquisition of America's leading raised access floor business at the time: Tate Global Corporation, trading today as Tate Access Floor. Several years later, in 2008. The Group acquired composite sandwich panel manufacturer Metecno Inc. USA. In 2009 Kingspan Solar Inc. opened its new offices in Maryland and in that same year Kingspan Insulation assumed full responsibility for the Kingspan KoolDuct System in North America.
Kingspan KoolDuct System includes panels, fabrication methods, coupling systems and a complete line of accessories to provide pre-insulated ductwork in sections up to 13 feet (3.93 m) long.
