A REVIEW OF COMPARATIVE EVALUATION OF THERMA`L INSULATION MATERIALS FOR BUILDING WALL APPLICATIONS

Attention towards the thermal performance of building materials, particularly thermal insulation systems for buildings, has grown in recent years. Thermal insulation of building walls has a significant effect on the reduction of thermal energy consumption in buildings Making a thermal insulation of a building external wall can in terms of economic aspects be approached as an investment. In this investment the cost is related to the purchase, transport and laying the insulation, whereas the profits are linked to the reduction of thermal energy consumption necessary to heat a building. Objective of this paper is to provide a comparative study of thermal conductivity material for packaging insulation which will hold up over a long period of years over relatively wide temperature ranges and which will prevent the passing of the insulating gas from the package to the exterior of the package and which will also prevent the passage of air into the package.
