PolyNex™ Fanfold represents a top-tier, rigid insulation solution featuring a robust closed-cell composition. Crafted from a premium-quality graphite polystyrene (GPS) foam core, it is both durable yet lightweight. This insulation is available with options for a clear plastic facer on both sides or a combination of a laminate facer on one side and a reflective foil facer on the other. These configurations provide resistance against air infiltration, protection from liquid water, and contribute to enhanced energy efficiency.
PolyNex™ Fanfold is manufactured to meet or surpass ASTM C578 standards. It establishes a uniformly smooth surface, ideal for applying residing materials in both residential renovation and commercial exterior wall applications.
PolyNex™ provides up to 20% more insulating value than standard EPS, allowing for more energy savings with the same amount of material. PolyNex™ Fanfold stands as a reliable choice, ensuring optimal insulation performance in a variety of settings.
