The efficiency of materials used for the arrangement of interior and inter-apartment partitions used in modern construction of the Republic of Kazakhstan is analyzed. Environmental and fire safety, as well as sound insulation properties of partition materials and products are accepted as criteria. It is shown that currently used foamed polystyrene concrete panels are technologically advanced in the installation of partitions, but do not quite meet the environmental and fire safety requirements. Partitions made of plasterboard sheets do not provide sufficient sound insulation in the interior space. One of the effective options is the arrangement of interior partitions from foam gypsum strip panels, in which functional requirements for materials in combination with economic benefits for construction organizations are the most fully provided. With a material thickness of 100 mm, the required sound insulation level of 41 dB for residential houses of category B and B regulated by the relevant interstate standard is achieved. The results of research on the development of technology of foamed gypsum strip panels with an average density of 600–800 kg/m3 are presented. It is established that the acceptable strength corresponding to the class of compressive strength B2 is achieved with the gypsum binder of G-5 grade at a material density of 800 kg/m3, with the binder of G-13grade – at a density of 700 kg/m3. To increase the bending strength of the material, cellulose and propylene fibers were used, the introduction of which in an amount of 0.2–0.4% increases the bending strength to 2.6–2.8 MPa. The introduction of finely ground gypsum stone provides a sharp increase in the rate of strength gain: after 25–30 minutes, the strength reaches 1.5–1.7 MPa, while similar strength samples without additives gain after 50–60 minutes. Thus, studies have shown the possibility of organizing the production of strip gypsum panels based on foamed gypsum. For introduction of technology of foamed gypsum panels in manufacture it is necessary to conduct tests of materials of natural size in order to set a minimum value of bending strength sufficient for demolding and transportation of the panels and also identify the equipment for preparation of foamed gypsum mixture
