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.

** NOTE TO SPECIFIER ** Kingspan KoolDuct can reduce air leakage rates to a fraction of those typical of traditional duct systems, cutting energy use, operational carbon dioxide emissions, and costs. Kingspan KoolDuct System should NOT be used in the following applications: conveying solids; fire resistant ductwork; kitchen or grease hood exhaust systems; chemical, fume or smoke exhaust systems; where combustible matter collects inside ductwork; adjacent to sources of extreme heat; outdoor or underground use without mechanical or weather protection; where failure of automatic control equipment may give rise to extreme temperatures; with equipment that does not include automatic maximum temperature controls. Outside of those limitations, KoolDuct system is suitable for new construction and retrofit projects in residential, commercial, institutional, light industrial and leisure sectors. KoolDuct is ideal for non-ferrous applications and projects where non-fibrous insulants are preferred, for example: food, beverage, and pharmaceutical industries; clean air and hygiene controlled environments; high relative humidity environments; sterile areas; healthcare; communication and server rooms; data centers. Contact the manufacturer for swimming pools and non-standard applications.
