Paratherm Non-Halogenated (NH) polyisocyanurate products by Siplast are now free of TCPP, a chlorinated organophosphate flame retardant that’s commonly added to polyurethane foams. With the elimination of TCPP, the Paratherm NH line is Red List-free and still provides stable R-value performance at mean temperatures of 40 and 75 degrees F.
The line includes flat, tapered, and cover boards available with GRF and CGF facers in a variety of PSI ratings to meet project needs. Paratherm NH contributes toward green building rating systems, such as LEED and the Living Building Challenge, and carries sustainability documentation, including Declare labels, GREENGUARD Gold, GreenCircle Certified Recycled Content, and product-specific EPDs.
