: Nowadays buildings are the largest consumer of energy because the cement plaster we use has low thermal insulation which leads to consumption of a lot of energy to keep the interiors of the building thermally comfortable. In the areas where the severe temperature fluctuations occur, a lot of energy is consumed in the form of fossil fuels, air conditioners, and other heating and cooling devices to keep the internal environment comfortable. So one of the best ways to reduce the energy demands in buildings is to reduce heat losses through the envelope. Thermal insulating plasters are the important means to face the energy efficiency issues in buildings. Use of Nano technology or aerogel based plasters and phase change material based plasters make a significant contribution to this field, reaching higher level of thermal performance inside the buildings. But these plasters are uneconomical and their cost is approximately 20 times higher than the conventional cement plaster. Thus new plaster solutions have to answer certain specific economical and technical needs to meet the market demand. The present research is an attempt to improve the thermal insulation of conventional cement plaster using conventional materials viz. polystyrene, polymer polypropylene, heated white clay, which otherwise are the wastes with almost zero scrap value. Experimental work was carried out and it was observed that by the addition of these materials the thermal conductivity dropped, making thermally efficient plasters able to meet real market and end users-demand. The present work describes the results of research that is oriented towards the development of low cost thermal insulating plasters by incorporating the conventional materials, which can be mainly due to the blocking of the path of heat transfer either by creating a porous structure as in case of polystyrene and heated clay or by preventing the direct grain to grain contact by incorporating material within the mix possessing high thermal insulation as in case of polymer polypropylene. In this attempt, different samples were prepared by incorporating different proportions. Results showed that thermal conductivity decreased by 84.4%, 58.0%, 92.2% for polystyrene based cement plaster, polypropylene based cement plaster, and heated clay based cement plaster as compared with conventional cement plaster.
