In the design and construction of residential and industrial buildings outbuildings, it is necessary to use effective thermal insulation materials that provide a comfortable microclimate in the room, as well as the required conditions for implementing technological processes. An essential factor is the reduction of the negative impact on the environment, which is expressed both in the reduction of energy consumption and in the possibility of rational use of industrial waste for partial replacement of the main raw material components. To increase the efficiency of heat-insulating materials based on foamed polyethylene, it was necessary to develop a technique for selecting the composition of synthetic polyethylene foam matrix, considering the possibility of using secondary modified polyethylene foam at different foaming modes. The compositions of modified polyethylene foam were selected using statistics methods and analytical optimization. The developed bases of optimization and composition selection methodology allowed to establish optimal consumption values of main components and process parameters corresponding to the specified requirements. Using alignment charts, the solution of the predictive problem of estimation of values of strength and average density of foamed polyethylene depending on the value of consumption of main components was realized.

Historically, scientific and technological progress has determined the emergence and continuous development of forms of its social organization, objectively forming the images of solidarity society corresponding to these forms. It is argued that the main social phenomenon accompanying scientific and technological progress is innovation, and it is hypothesized that this concept can be based on the ontological concept of innovation. On the basis of well-known methods of ontological research, the method of dialectic-systemic construction of innovation as a system of unitary social activity which generates new opportunities of social development leading to growth of social quality of the solidarity society is proposed. The system-activity concept of innovation is substantiated and its invariant conceptual structure, which is defined as the unity of two innovative structures: the phenomenon of innovation and the manifestation of innovation, which determine the organization and management of innovation, is constructed. The proposed concept of innovation can only be the imperative of sustainable social programming of a solidarity society, which provides a method of dialectical-systemological construction of innovation that allows detailing the original invariant conceptual structure for each specific image of a solidarity society due to a particular stage of scientific and technological progress.

The resort town Sochi is a municipality on the territory of Russia in the Krasnodar Krai. The location in the mountainous area and the proximity to the sea makes the Sochi city special in terms of the variety of possibilities for the resort services provision. In addition to a beach holiday on the Black Sea coast, Sochi is a place of attraction for the lovers of outdoor activities in the mountains: alpine skiing, snowboarding, mountain biking, and tourism. Historically, the city of Sochi is an all-Russian health resort, because in addition to favorable climatic conditions and the proximity of the sea, there are unique sources of mineral water and the balneological resort Matsesta, where tourists from all over the country and from abroad come for treatment all year round. More details about the current state of the region, plans and development prospects are presented in the scientific works [1-4, 5-7].

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.

The article presents the results of the implementation of promising areas of construction and construction of low-rise buildings. The problems of improving the environmental safety and financial stability of agricultural construction through the implementation of effective systems that provide energy conservation, the creation of comfortable conditions in the rooms are considered. It is noted that a factor that has been given special attention in recent years is the environmental safety of the materials used and the reduction of the negative load on the environment of systems using these materials. The article provides the rationale that the heat-efficient system should not only be based on the use of materials with low thermal conductivity, but should also suggest a reasonable minimization of the joints between the products included in the insulation sheath and between products and structures. In constructions with the use of polyethylene foam, seamless insulating sheath is formed, which has high thermal resistance. The low vapor and wind permeability and moisture conductivity of polyethylene foam makes it possible to dispense with the construction without additional vapor barrier and wind protection, which improves the performance of the casing and its durability due to the reduction in the complexity of manufacturing wall structures.

The article outlines the basic requirements for pitched roof insulation systems. The analysis of the properties of thermal insulation materials used in insulation systems was conducted. It is substantiated that the thermal resistance of such structures on the surface of the roof is formed taking into account the thermal conductivity of thermal insulation, thermal conductivity of wooden rafters and heat loss through the leakiness of joints and mounting devices. An assessment was made of the effect of loads of various types on the heat-insulating layer, namely: the effect of the air flow in the ventilated gap; the movement of the vapor-air mixture in the material; condensation of water vapor and penetration of drip liquid; exfiltration of air at the joints of the plates and on the surfaces of contact with the supporting structures. The expediency of using products on the basis of unstitched polyethylene foam in the construction of pitched roofs with a wooden roof system, taking into account the advantages and features of this material, as well as taking into account the possibility of creating a seamless insulating shell, is substantiated.
