POLY SHIELD FAN-FOLD is cut in vertical 25" increments along it's 4'x50' expanse allowing the panels to lie flat. FAN-FOLD provides a smooth resilient underlayment which eliminates the potential for "oil canning" or "telescoping".
FAN-FOLD is made of Cellofoam Expanded Polystyrene (EPS) rigid insulation, faced with a tough poly laminate on both sides. Standard thicknesses are 1/4", 3/8" and 1/2". Standard densities are 1# and 1.25#.
Because FAN-FOLD is made of millions of closed cells of expanded polystyrene, it has an excellent resistance to heat transfer. Not a vapor barrier.
When FAN-FOLD is properly installed it doesn't deteriorate with age, is resistant to mildew, rot, fungus, bacteria, and doesn't require maintenance. The tough facings resist abuse during construction and prior to the installation of siding materials.
