Alternative heat insulation method for rigid construction walls

Abstract

The purpose of heat insulation is to minimize the heat transfer between the interior and external environment. Besides, it helps to prevent the structure of the constructions from the harmful heat effects because of heat transfer. This study presents an alternative method to achieve heat insulation in concrete walls. 4 various heat insulation materials as wood shavings, fiberglass, granule rubber, and styrofoam were added into the concrete wall parts and an enclosed volume was created using those. The interior temperature of the enclosed volume increased using resistance and the temperature was measured with a thermocouple as well. In order to calculate the thermal conductivity of heat-insulated walls, measured temperature, power consumption, and surface area were used. As a result, it was shown that the wood shavings insulation in concrete had a lower thermal conductivity coefficient than others and much efficiency as well. Besides, the presented methodology could help to prevent lacking energy resources and to save economical incomes.
