Systems of application of light steel thin-walled structures have existed for more than half a century and serve primarily for the construction of frame buildings of various purposes in the shortest possible time with minimal resources. However, during this time, there have not been enough research carried out on the insulation and acoustic parameters of such structures. The objective of this research is to investigate the heat-protection properties of thin-walled, light steel structures. The article presents the results of calculation of the temperature-humidity regime in a year-long cycle of operation with determination of condensation zone of frame-sheathing walls from light steel thin-walled constructions with and without the use of vapor insulation layer. Computer modeling for the conditions of the city of Moscow of moisture distribution in the thickness of the structure, moisture accumulation over five years of operation was carried out. Thermograms of the operated object are presented. It has been established that without a vapor barrier layer in a frame-sheathing wall made of light steel thin-walled structures, the maximum moisture in the first year (during the period of greater moisture) of operation is 29 wt. % in the heat-insulating layer. In the second year there is an increase in the maximum humidity to 34% of the mass. In the following years (up to 5 years) the maximum humidity does not exceed 34% of mass. With the use of steam insulation, the maximum humidity during the second year of operation is approximately equal to the operational humidity for the “stone fiber plate” with a density range from 80 to 125 kg/m3,Wb = 5%; according to reference data SP 50.13330.2012 “Thermal protection of buildings” Annex T. The first year of operation 5%, the second year 5.6%.
