Abstract

The air-bubble sheet has been widely used to wrap fragile products for long-distance transportation. The further usage of the air-bubble sheet as a thermal-insulation material for the reduction of the thermal conductivities of window systems has occurred because of its low price, in addition to its thermal-conductivity properties. In this study, the thermal performances of a variety of commercial air-bubble sheets according to various applications were evaluated. The experiments were performed with single-glazed and double-glazed windows and three types of air-bubble sheets of different air volumes. U-values are used and were calculated for the determination of the thermal performances that are based on the KS F 2278. The maximum decrease of the U-value was measured as 1.092 when a sheet was attached onto the frame of single-glazed window. The square-like air-bubble sheet that contains the largest air volume shows the highest thermal-resistance value. Double layers of the air-bubble sheets show better performances than those of the single layers on both sides of the windows.
