Low-Emissivity Insulation has enclosed reflective air spaces between aluminum foils that have very low emissivity. The reflective air spaces are composed of optimum-sized air cells, which are enclosed by polyethylene foam. The critical difference between Low-Emissivity Insulation and conventional reflective insulation is the presence of a honey-comb structure formed from polyethylene that serves as the core material. Low-Emissivity Insulation has a foil surface emissivity of 0.04 with enclosed air cells between foils. Its core material is polyethylene foam with 35 times expansion, which is expanded to make air cells. The enclosed air cells with foil reduce convective and radiative heat transfer. To verify the high efficiency of Low-Emissivity Insulation, it was tested by an accredited laboratory designated by the Korean government. Comprehensive thermal transmittance tests were conducted for the Low-Emissivity Insulation of specimens of various thicknesses. The thicknesses of the specimens were 10, 20, 30, 40, 50, 60, 80, and 100mm. Based on the test results, its insulation-affecting factors were investigated using a trial-and-error method.
