Paratherm^® NH Polyiso Insulation is an option that is Red List-free/TCPP-free and qualifies for many sustainable certifications. Our formulation now uses a Red List-free, non-halogenated flame retardant. Paratherm^® NH products offer low temperature stable R-value when tested per ASTM C518 at 75°F and 40°F mean temperature, making it a higher performing insulation product.  Paratherm^® NH products offer the highest thermal value per inch of any rigid insulation foam plastic, meeting the same codes and approvals, with the same offerings as standard formulation polyiso.

Paratherm^® NH polyiso products come in a choice of facers: a glass fiber reinforced cellulosic organic facer (GRF) or a durable coated glass fiber inorganic facer (CGF) bonded to a core of polyisocyanurate foam insulation. GRF facer is standard, while CGF facer is premium due to its moisture and mold resistance* properties, and higher strength and durability. Paratherm^® NH polyiso products are compatible with many SIplast systems and offer a variety of attachment methods.
