Features of Realization of Insulation Systems under Conditions of the Far North

Features of the realization of insulation systems under the extreme climatic conditions, including the conditions of significant negative and freeze-thaw temperatures, high wind speeds etc. are outlined. It is noted that the adaptation of building systems to such conditions of operation imposes special requirements and to heat insulation materials concerning their resistance to mechanical and climatic impacts as well as to the stability of properties for the whole operation period. Results of the study of operational durability of non-cross-linked polyethylene foam, which confirmed the inertness of the material to humidity and temperature impacts within the interval from -60 up to 80оC, made it possible to recommend the products on its base (mats and rolls) as insulation for objects of the Arctic Circle. In particular, the project of insulation of the residential module of the two- link tracked transporter was realized. Tests conducted during the Arctic expedition in 2017 in the Republic of Saha (Yakutia) show that the heat insulation on the basis of non-cross-linked polyethylene foam makes it possible to provide the sustainability of the living module during two months at an ambient temperature of -45оC in strong winds with gusts up to 30 m/s.
