Abstract

Low-Emissivity Hybrid Insulation has been developed in South Korea. It combines both resistive and reflective insulating principle. It is composed with many layers of reflective aluminum foils and honeycomb-structure air cells with polyethylene foam. This paper introduces recent South Korean building insulation code and the applications of Low-Emissivity Hybrid Insulation to meet the code.

Summary

Introduction

Low-Emissivity Hybrid Insulation is a multilayer product consisting of layers of aluminum foil and a honeycomb structure produced from polyethylene foam. The enclosed air cells with foil reduce convective and radiative heat transfer [1]. This paper discusses the insulating characteristics of Low-Emissivity Hybrid Insulation depending on heat transfer paths and materials. This means that Low-Emissivity Hybrid Insulation is divided into two parts according to the heat transfer paths such as reflective. Comprehensive thermal transmittance tests were conducted for the Low-Emissivity Hybrid Insulation of specimens of various thicknesses. Based on the test results, its insulation-affecting factors were in-vestigated using a trial-and-error method
