The article deals with the problems of eff ective insulation for housing construction. The most commonly used heaters in our country are polystyrene and mineral wool. The advantages and disadvantages of these heaters, and proposed the idea of creating an alternative insulation based on foam glass composition are studied. This material is stripped major drawbacks polystyrene and mineral wool. It is durable, durable, non-fl ammable, water-resistant, environmentally friendly, and has a number of other advantages. The disadvantage of the material can be considered its high cost. To reduce the cost of insulation it is supposed to consider the possibility of introducing into its composition various additives, including industrial waste, which will help solve up-to-date environmental problems.

Absract. The paper deal with the development of energy saving technology for obtaining thermal insulation material on the basis of liquid glass. The aim of the research is to study processes of chemical and physical modification of soluble sodium silicate and change its rheology. The paper also considers development of technology for the production of thermal insulation material with porosity uniformly distributed throughout the volume and with the specified pores size. In this research the authors used both traditional methods (chemical analysis, physical-mechanical tests) and "thin" methods, i.e. differential thermal analysis, electron microscopy. For research in the field of rheology changes the authors developed a methodology for determination of viscoelastic properties of materials with variable rheology. For the development of resource-saving technologies the researchers used the method of laboratory simulation which is as close as possible to real production conditions. The research identifies regularities of processes of modification and swelling of liquidglass compositions and suggests methods for increasing viscosity of liquidglass compositions by introducing various modifying additives. It also introduces an energy-saving technology of porous granular material production, and proposes options for the production of effective thermal insulation material based on sodium silicate composition.
