DEVELOPMENT OF ENERGY-SAVING HEAT INSULATION FOR HOUSING STOCK IN KURSK AND KURSK REGION

Abstract

Exterior wall envelopes of buildings and structures are the main elements through which heat loss mainly occurs during the heating season, especially in case of changeable weather conditions and subzero ambient temperatures. In compliance with SNiP23-02-2003 «Heat insulation of buildings», one of the main parameters providing reduction of heat losses through envelopes of enclosure is heat transfer resistance of walls, windows, floors and ceilings. It is necessary to involve heat insulating materials in their design. The greatest heat loss in buildings takes place through walls (42-49% for five-nine-storey buildings) and windows (32-35%). Since the surface of exterior multi-layer in situ walls of a multi-storey building is quite big, heat loss into the environment is of a maximum value. The authors have developed design solutions for a multi-storey in situ wall with extra heat insulation. Twisted fine-fibred basalt bundles produced by Kursk enterprises are used for such heat insulation, which reduces costs of constructing of buildings and facilities of different purposes
