EFFECTIVE HEAT-PROTECTIVE SYSTEM WITH THE USE OF THERMAL INSULATING SOLUTION OF REDUCED DENSITY

Abstract

Introduction. The manuscript is devoted to the actual problem of thermal insulation of buildings and structures. The paper presents a developed low-density insulation solution with improved heatengineering characteristics. The aim of the work is to increase the efficiency of the heat-shielding system using a low-density heat-insulating solution.Methods and materials. The authors carried out tests at the site of heat engineering control of LLC «Intellect-service-ZBK-1» to determine the resistance to heat transfer of the enclosing structure.Results. The construction of the wall system consisting of the «Aerobel» D500 gas-silicate block (625×200×250 mm) and made on a low-density heat-insulating masonry mortar, as well as with the use of a heat-insulating mortar and a universal «Moutrical» energy-efficient coating allowed increasing actual reduced heat transfer resistance from 0.9 to 1.4 (m2 ·K) / W (by 36%).Discussion and conclusions. Laboratory research and field tests that meet the requirements of state standards and that develop low-density heat-insulating plaster demonstrate the low-density heatinsulating solution, which indicates the feasibility in thermal insulation of buildings and structures. The authors achieve special economic and ecological effect in connection with the use of local raw materials and waste production of expanded perlite sand.
