Roof Insulations for Public Buildings in Hot Climate

Due to higher solar radiation roofs are the most affected area in the envelope of the building, hence giving an utmost importance to thermal behavior as the main concern to compare any cool roof. Various calculations are taken to find the thermal performance and then comparison in thermal behavior is carried out. Limitation of any technique is critical importance along with its economic effect to select any type of cool roof. This research compares various cool roofs on basis of thermal behavior, economy and their limitations. This research will help the architects and designers to make wise choice regarding perfect selection of roofing material in case of thermal behavior, economy and limitation of any technique or material to make the roof cooler.
