This article examines the peculiarities of social adaptation of migrants in urban space (cities). Today, the migration becomes an urban phenomenon, because migrants choose cities for bigger opportunities and realization of personal potential. For the quickest possible adaptation in urban environment, a migrant accumulate all of the adaptive capabilities that transform his attitude to work, behavioral strategies, and interaction with people. In important also belongs to the migrant social institutions (diaspora). Russian keeps up with the global trends: the percentage of migrants residing in urban settlements is growing, which leads to closer interaction between the accepting urban community and the migrants. The rate of migration to Russian remain persistently high that especially affects the cities, in which the infrastructure capabilities do not correspond with the size of available population, but the level of economic development is higher than in the countries of origin. This is namely why the municipal authorities should give careful attention to regulation of social adaptation of the migrants, using various socioeconomic instruments, implemented in separate municipal formation, because currently, there is no integral practical component of social adaptation of the migrants in cities.

The heat insulating materials that reduce the thermal losses of buildings and constructs will play the key role in their energy performance. The low-vacuum insulation panels are an effective alternative to the non-vacuumed heat insulating materials due to the lower coefficient of thermal conductivity. The goal of this research is to examine the potential application of silica fume, aluminum byproduct as a filler for vacuum insulation panel. The author examines the properties of silicon dioxide powder, develops the composition and technology of production of the vacuum heat insulating panels on its basis. The article explores the silica fume – byproduct of crystalized silicon of Bratsk Ferroalloy Plant, which annual putput is 30,000 tons. The acquired results allow assuming that for manufacturing of the low-vacuum insulating panels can be used not only factory produced powder, but also less expansive powders of silica fume – the byproduct of crystalized silicon. In future, the use of byproducts can become the foundation of production of the high-quality vacuum insulation wilt low cost.
