Abstract: The use of thermal and acoustic insulation consider the most important and effective methods for a comfort environment in residential buildings which it's reduce the effect of heat in summer and coldness in winter, also, reduce the noise from using air-conditioning system and the surrounding noise, all that will results in cost and energy saving. In this study, simple and available raw materials is used in order to have coating layer which is easy to prepare and apply on exterior walls of buildings that can give the required properties and specifications, these materials are (polystyrene, polyester resin, mullite nad TiO2 nanoparticles), the concrete and cement mortar is used as substrate. Coating process for samples surfaces carried out by cold spray technique using air-brush and air-gun sprayer, the coating layer prepared from raw materials (polystyrene and polyester), mullite was added with different ratios (1, 3 nad 5%) also, another layers prepared with the same ratios with the addition of 2% and TiO2 nanoparticle, the samples coated with different layers then all set to make the required tests and study their properties to find out its feasibility in different environments. A measurements was made to find out the effect of the used materials and the additions by studying Scanning Electron Microscope (SEM), thermal conductivity by (Hot Disk device) to find out the best coating layer and their ratio, UV resistance test to measure the degradation rate, then numerical analysis using ANSYS 11 to analyze thermal insulation and image processing used to analyze sound insulation. The results show improvement in UV radiation resistance the results shows that the best resistance was up to 66.6% for day one and raised up to 90% for day seven of test. A comparison made between the numerical results and experimental results, generally the coating layers improves concrete and cement mortar resistance to external thermal effect, the best result was measured for the sample with 5% of mullite powder and (2%) of TiO2 nanoparticles in spite of the results of thermal conductivity, sound analysis using image processing technique show that the coated sample with 5% of mullite powder and (2%) of TiO2 nanoparticles gives the best sound insulation compared to uncoated cement sample.
