POLYDAMP® Low Emissivity Foam (PLE) Low Emissivity Foam (PLE) is a lightweight composite insulation material designed to address all three thermal issues: conduction, convection, and radiation. It is an ideal insulation material because of its composite construction of a reinforced aluminum foil on either side of a low-density, closed cell thermal insulation.
