New Formulation

         DuPont™ Performance Building Solutions has announced its reformulation of Thermax™ polyisocyanurate insulation to remove halogenated flame retardants.  This new product formulation is another step in DuPont’s journey to deliver safer-by-design innovations.

         With this reformulation, DuPont is the first Class A polyisocyanurate (polyiso) sheathing manufacturer to phase out the halogenated flame retardants commonly used in building insulation polyurethane foams.  The resulting Thermax Non-Halogen (NH) Series products represent the first polyiso, Class A, non-halogen, and LBC Red List Approved products in the North American above-grade commercial wall systems market.  Thermax NH Series has achieved an LBC Red List Approved designation, meaning 99% ingredients present and disclosed, at or above 100 ppm in the final product, do not contain any Red List chemicals.  This designation can be used to obtain LEED® v4 and v4.1 credit.

         With its unique glass fiber-reinforced foam core and high R-value, Thermax has a long history of making buildings more comfortable, while helping reduce building energy use, and the carbon footprint.  They are specially designed for use as both exterior continuous insulation and interior finish systems for walls and ceilings.  Facers can be pressure-washed and protect the boards from jobsite damage.  Thermax NH Series products maintain the same exceptional quality and thermal performance as the original, in a Class A, non-halogen, safer-by-design formulation. 

         Additional benefits include: consistent, high performance R-value at both 75°F and 40°F; can be left exposed on interior walls and ceilings without a thermal barrier, UL 1715; and low VOC, HFC free, and zero ODP.

         DuPont is a global innovation leader with technology-based materials and solutions that help transform industries and everyday life.  DuPont employees apply diverse science and expertise to help customers advance their best ideas and deliver essential innovations in key markets including electronics, transportation, construction, water, healthcare, and worker safety.
