“…Firstly, thermal resistance along the smooth surface of the wall. Secondly, the thermotechnical homogeneity of the insulating shell, namely, the reduced thermal resistance, taking into account heat fluxes through windows, doors, and heat-conducting structural elements called cold bridges [1][2][3][4].…”

The article discusses the results of studying the thermotechnical properties and energy saving factors of insulation systems based on mineral wool products and products based on extruded polystyrene foam under conditions close to natural ones. The studies were carried out on the basis of the hypothesis according to which the heat-saving characteristics of the facade insulation systems are most dependent on the thermal resistance along the surface of the wall, on the thermotechnical uniformity of the insulating sheath and on the stability of the properties of the heat-insulating materials under real operating conditions. The implemented complex made it possible to establish that the smallest difference between the air temperature in the room and the surface temperature in the lower zone was achieved on a fragment of the building envelope with a mounted facade system with XPS as insulation. For the same type of facade system, the maximum heat transfer resistance in the lower zone of the building envelope was reached - 2.72 m2 ° C / W for the cold period of the year, which significantly exceeds the characteristics of the system of mounted ventilated facades with mineral wool thermal insulation in the corresponding zones. The factor of “additional warming” from the soil, which is used to justify the rejection of warming in the buried part of the structure, does not work in the cold season. Flooding at thezone with the junction of the wall with the soil significantly affects the values and nature of the distribution of operating humidity inside the insulation layers.

“…A complex of modifying additives is added into the composition of the clay and gypsum binder, as well as into the plaster dry building mixtures. The applying of additives allows you to adjust the properties of clay and gypsum systems and makes possible the occurrence of synergistic effects, which must be confirmed experimentally [1][2][3][4][5].…”

The applying of local building materials is an effective contribution to the savings of mineral resources, which are used for the production of basic building materials. Clay and gypsum compositions are the local raw materials in many regions of the country and some neighboring countries. The article discusses the method for determining the clay fraction in the clay and gypsum composition, as well as the method for assessing the rheological characteristics of the plaster mixtures for interior work based on clay and gypsum binder. It was established that the content of the clay fraction in the studied clay and gypsum composition is in the range of 30–32%. Plaster mixtures based on clay and gypsum binder can be considered as optimal compositions under the following conditions. The grade of mobility is not less than PK3 (8–12 cm) in cone penetration test, the ultimate shear stresses in the first seconds of the thixotropic hardening ensure no runoff for the adjusted thickness of the applied layer. With the mentioned mobility, the “creeping” on the concrete surface is 10% and less, and the “creeping” on the brick surface is no more than 5%. The allowable water-solid ratio is 0,46–0,50.

“…The main function of insulating materials and products is creation of insulating envelopes; however, the application of thermal insulation may be detailed from the point of view of the result [1][2][3][4]. First, formation of thermal insulating envelopes is focused on the reduction of heat losses from inside outwards.…”

Various aspects of application of polyethylene foam implemented for roof thermal insulation within the frame of one of the sports venues and, closely, the realization of insulation systems for cold conservation on the territory of public sports facilities, particularly for snow storage conservation within ski resorts have been regarded in this article. Additional demands are placed on thermal insulating material for suchlike constructions. Apart from high thermo technical properties, the material should involve hermeticity, lightness, easy mounting and maintenance, durability, bacterial and fungal resistance and temperature differential resistance. The examination results concerning properties and particularities of application of non-cross-linked polyethylene foam within the scope of production of insulation coatings protecting the snow from melting are given in the article. It has been established that being the part of insulation system polyethylene foam preserves the accuracy of mechanical and thermo physical characteristics. Taking all functional particularities of insulation systems implementation into consideration, the principles of protection and conservation of snow covering have been developed being realized on the mountainsides and plateaus of ski resorts. Polyethylene foam rolls have been connected in a butt joint and mechanically fixed. As a result, a seamless insulating coating - thermal blanket has been formed, which covered the entire mountainside. Maintenance of insulation system is performed during the off-season between March and September in the period of stable positive temperatures.
