The results of the study of fine-grained feldspathic and talcchlorite waste from Republic of Karelia’s mining companies as a new mineral product for heat-insulating materials and stationary heat accumulators (fireplaces and furnaces) are reported. The physico-mechanical and thermal-physical properties of the materials, based on finely ground waste and local clay, are appraised. The materials produced from pegmatite waste are highly strong, and can be used for lining furnaces and fireplaces. Heat-insulating materials based on talc-chlorite waste have low thermal expansion at 20‒900 °C, their thermal resistance increases 9 times (at 980 °C, water) and their mechanical strength is 2,6 times higher than that of samples containing talcum powder.

The paper presents the theory of calculating heat loss through the fences of timber drying chambers. The software for computer modeling of the process of transferring heat energy through the fences of the drying chamber, consisting of various heat-insulating materials, for calculating heat losses during drying of sawn timber is described. The efficiency of the use of modern heat-insulating materials to reduce heat losses during drying of sawn timber has been experimentally confirmed.

This article reviews energy consumption in the Kyrgyz Republic economy, environmental indicators and strategies to further develop the national fuel and energy system to ensure energy efficiency and energy saving. An existing situation in energy efficiency of buildings in the country is described. Secondary legislation and by-laws approved by the Government of the Kyrgyz Republic as well as several technical standards, norms, methods and guidelines approved by the order of the State Construction Agency of the Kyrgyz Republic are presented. Applying modern insulating materials are suggested as possible solutions to increase energy efficiency and energy saving. The advantages of EPS-beton in comparison with other thermal insulation materials are discussed and foreign experience of use of EPS-beton products in increasing energy efficiency of buildings is presented.
