In view of the growing population and urbanization, it is necessary to ensure the development of advanced building materials capable of ensuring the quality of living conditions with as low energy consumption as possible. A proven way to achieve this is to create a composite material with a lightweight aggregate. However, the use of lightweight aggregate could also affect other material properties, such as mechanical strength or water absorption. In this study, the silica sand aggregate was partially and completely replaced with foam glass gravel in the composition of natural hydraulic lime plasters in order to reduce thermal conductivity of the material. The use of foam glass is also profitable with regard to the environmental aspect, due to its recyclability. The effect of application of glass gravel on the structural properties, mechanical strength, thermal properties, and water transport parameters was studied for 28-days cured samples. According to the results, the application of foam glass gravel significantly reduced the thermal conductivity of the plaster while maintaining its sufficient strength despite the increase in high porosity, even when the silica sand aggregate was fully substituted. Based on the data obtained, it was concluded that the use of foam glass as a filler is beneficial in improving the thermal properties of plastering mortars.
