Heat Insulation of Roofs

Heat Insulation of Roofs      The heat form sunlight is easily penetrating into building in case of building built in hot climate areas. In such cases, the heat insulation is necessary. The amount of heating depends up on type of building material used for roofing, roof height, ventilation, environmental exposure, etc. for example the thatched roof does not get heated up as much as a concrete roof. Most commonly used insulation of concrete roofs: Applying heat insulating material above the roof: material like cooling membrane, water proofing coating, cooling paints, vapour barrier Applying the insulation material under the roof: material like dropped ceiling (commonly known as false ceiling) is best option for heat insulation in concrete building. Material like plaster of Paris is good heat insulation material which used for dropped ceiling. White washing on the top of the roof: white colour is reflecting the sunlight and prevent heat penetration into the building Use of reflecting material:  such as aluminium foil or reflecting paint or solar panels insulating heat penetration into the building Shading on the roof: spraying of water, growing vegetation (creeper) or other means of heat insulation to be provided above the roof Increase ceiling height: ceiling height is one of the major factors that influencing in heat insulation. Higher roof height provides good air circulation and ventilation. It will reduce the heat. Commonly the height of roof kept 10ft (3m) in residential building. Laying of tiles above the roof surface: Lot of heat insulating tiles available in the market. Laying of those tiles is gives better benefit of result for heat insulation.
