Paratherm^® polyiso products offer the highest thermal value per inch of any rigid insulation foam plastic. Available with a choice of facers—a glass fiber reinforced cellulosic organic facer (GRF) or a durable coated glass fiber inorganic facer (CGF)—both bonded to the core of polyisocyanurate foam insulation. GRF facer is standard, while CGF facer is premium due to its moisture and mold resistance* properties, higher strength, and durability. Paratherm^® polyiso products are compatible with many Siplast SBS-modified bitumen, STP, and single-ply systems and offer a variety of attachment methods.
