The paper presents the research on the choice of the most effective grouting method for the liquid glass granulate by the binder based on liquid glass during production of composite insulation materials by their bloating under the microwave irradiation. The choice of the grouting method is carried out by determining the basic physical and mechanical properties of thermal insulation materials depending on the ratio of the granular filler to the binder. The research has shown the feasibility of obtaining composite insulation materials by volume grouting, i.e. simultaneous bloating of the granular filler and the liquid glass binder, which prevents shrinkage, cracks, foam collapse and formation of large voids due to close packing of contacting granules and uniform distribution of the bloated binder that fills the intergranular space. Therefore, such materials are characterized by better physical and mechanical properties.
