| Abstract: | In plain regions of our country, specially areas having hot-dry summers, generally two types of treatments viz Lime Concrete Terracing or Mud Phuska with Brick Tiles are being used on common flat pakka roofs for thermal comfort. Although these treatments provide thermal comfort to some extent in day time in summers but due to large mass and thick layers of the treatments, indoor heat is hardly removed through the roof upto late evening hours. Besides the higher cost of the treatments, due to the above mentioned disadvantages, occupants or users do not feel sufficient thermal comfort in hot dry areas. On the other side the application of cost effective thin layer of white glazed china clay tile pieces provides better thermal comfort. The benefits and effectiveness of the application of white glazed china clay tile pieces, its comparison with mud phuska and lime concrete terracing and laying system have been described shortly in the paper.
This treatment may be applied on old roofs having lime concrete layer or simple rendering with mortar as well as on new roofs. More than one lakh square feet area of terraces have been covered with this system by many govt. and Pvt. Organizations and individuals. Some practical implementations which have been made in and around Roorkee and metropolitan cities have also been briefed in the paper. Feed back studies about treatment on various buildings , show its energy saving efficacy and good thermal comfort performance. |
