What is Poly-fold Fanfold?

Poly-Fold Fanfold is a high-performance, rigid insulation consisting of a closed-cell, strong, but lightweight premium quality expanded polystyrene (EPS) foam core. It is available with either a clear plastic laminate facer on both sides or clear plastic laminate facer on one side and a reflective foil facer on the other provides air infiltration resistance, liquid water protection, and improves energy efficiency. All Poly-Fold Fanfold products meet or surpass the requirements of ASTM C578, Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation.

Poly Fold is water-resistant, has outstanding stability, and compressive strength which makes it ideal for residential, commercial, and industrial projects. It is practically impervious to moisture, while insect and mold resistant as well. The “Bug Barrier” additive that is embedded into Poly-Fold Fanfold deters carpenter ants and termites.

Poly-Fold Fanfold is environmentally safe, 100% recyclable, and an Energy Star approved product.
