Abstract:
Thermal insulation of buildings is essential for effective temperature control for the minimum possible consumption of energy that may be used to keep the atmosphere warm in winter through heating, and cool in summer through air conditioning. Systematic studies have been carried out in western countries to minimize the use of energy for heating with the help of thermal insulation. However, this is equally important for tropical countries like ours as well. Because direct exposure of roof of a building to sunshine during hot days of summer cause lot of discomfort inside the rooms due to conduction of heat from the top. Therefore, thermal insulation of roof or ceiling is essential so that the inside temperature may not be adversely affected drastically. This is particularly important in the plains of Pakistan where the temperature soars to 52°C. Therefore, attempt has been made to check the effectiveness of clay tiles as roof thermal insulation which is inexpensive and locally available in plenty. A systematic study has been carried out, the results of which are presented in this paper. The results are encouraging and a temperature reduction of up to 15°C has been achieved. On the day when out said temperature was 47°C the inside temperature was only 32°C.
