Developing Nano-Insulation Materials to Enhance the Energy Saving for Cooling a Traditional House in Hot Arid Climate

Abstract

The importance of this study relates to thermal insulation applications, where there is a need for efficient insulating materials with smaller wall thicknesses. This work compiled experimental findings on the thermophysical characteristics of the materials, such as the thermal conductivity of some nanomaterials mixing with epoxy to produce a new material with thermal insulation performance to reduce the thermal conductivity of building walls and roofs. These nanomaterials include Aerogel, silicon dioxide, and siloxane. The diameter of the particles has been checked by a particle size analyzer, while the structure of the composite has been tested by the SEM images. The coefficient of Thermal conductivity is significantly influenced by several parameters such as temperature, humidity and thickness. The temperature of the material is the most important factor, whereas thickness has a much smaller impact. The article concludes that there are numerous potential uses for aerogel, and one of them is for superthermal insulation. The study's objective is to contrast a conventional wall that commonly uses commercial thermal insulation materials with a composite wall that contains nano-insulation materials. The nanomaterials that were used  for mixing of Aerogel/epoxy, Silicon dioxide/epoxy, and Siloxane nanoparticles in proportions of 1.5%, 3%, and 6% wt, respectively. According to research, 3% of these Aerogel/epoxy nanoparticles significantly improve insulation's thermal properties when compared to residential insulations.
