Title of the articleThermal resistance of walls with insulation materials loose on the basis of sawdust
Abstract.The article describes the experience of the problems of energy saving buildings and structures through the use of effective thermal insulation materials in the country and abroad. The authors of the articles are designed compositions of bulk materials based on filings with the addition of gypsum, lime and antiseptic ingredients. The resulting heat-insulating material is rot and caking, inexpensive, easy to manufacture and environmentally safe. The main area of its possible applications are low-rise buildings frame type, as structural elements of the framework that use metal or wood. In this paper we present a calculation of the Thermal walling using material developed by the optimum composition. Thermal calculation includes the determination of thickness of the insulation layer. Design exterior fences built on the principles of limiting the amount of heat lost by the enclosure during the heating season and to maintain the inner surface of the outer enclosure temperature at which the inner surface of no condensation. This paper presents a technical solution design exterior walls. The calculation of steady-state temperature field in the enclosure. A limitation of temperature and moisture condensation on the inner surface of the cladding. Calculated moisture conditions walling. Checking the cladding on the air permeability showed that it meets the requirements. As a result of the calculations indicated that the application of the developed material as an insulator in protecting designs can provide all the thermal performance of the building with wall thickness not exceeding 26 cm.
Keywords.Loose insulation, wood chips, thermal conductivity, building envelope, heat engineering calculations.
