“…Of the study, the results of which are presented in the article show that the properties of polyethylene with the addition of 25% recycled polyethylene are not fundamentally different from the unsewn properties of polyethylene foam to clean the raw material. Accordingly, all the possibilities of the new material remain [14][15][16].…”

Insulation systems of building structures involve the solution of the following group of tasks: creation of favorable conditions for the work of structural elements and construction as a whole; optimization of heat losses through the insulation shell; creation of comfortable conditions in the room. Such a system would function normally if effective thermal insulation, including polyethylene, were used. The price of polyethylene foam can be reduced without prejudice to the properties in the case of the use of secondary polyethylene foam. The article presents the results of experimental studies, the purpose of which is to optimize the composition of polyethylene foam with the addition of secondary polyethylene, the formation of methods of selection of its composition and the development of systems for the application of products based on polyethylene foam. The article presents the main provisions of the method of analytical optimization, which allows to significantly reducing the material and time costs of processing the results of the experiment. The article deals with aspects of the implementation of construction systems using products based on polyethylene foam in terms of minimizing heat loss through the contact areas. Mandatory criteria for the construction and implementation of insulation systems are safety conditions, including both structural safety (including maintenance-free cycle) and fire safety.

“…The main structural types of low-rise buildings are the following structural systems: massive wall (monolith, brickwork, masonry from aerated concrete blocks or stones) with external insulation; frame system (on a metal or wooden frame), frameless system based on profiled metal sheet [12][13][14]. All information about these systems, their design features and properties, as well as information on the source materials that are elements of these systems are necessary components of information models.…”

The article discusses the possibility of using the criteria of energy saving, cost and comfort as an estimate criterion in the analysis of information modeling technologies for low-rise buildings at the stages of design, implementation and operation. The insulation systems of low-rise buildings, including frame type, are considered as an object of study. Different types of insulation systems of frame buildings are considered and, as a result, the expediency of using rolled polyethylene foam as an insulating material is established. Its use allows to form a seamless insulating sheath with minimization of heat transfer bridges, as well as to eliminate the use of additional wind-proof and vapor-insulating membranes. The regularities of the influence of operating factors on the thermal resistance of the insulating shell are established. The data obtained as a result of the implementation of experimental studies allow us to state that low water absorption and low vapor permeability of the insulating layer exclude the possibility of its wetting and degradation of heat-shielding parameters. The stability of the properties of the insulation sheath and the construction of the walls as a whole is ensured during the entire period of operation.

Introduction. The article discusses the various aspects of the use of foamed polyethylene, implemented at sports facilities in Armenia. Firstly, it is a roof insulation system. Secondly, the implementation of insulation systems to preserve the cold in the territory of open sports facilities, in particular, to preserve snow reserves in ski resorts. Additional requirements are imposed on the thermal insulation material for such structures. The material, in addition to high thermotechnical properties, must be airtight, lightweight, easy to install and maintain, durable, resistant to infection by bacteria and fungi, it is easy to tolerate temperature extremes. Materials and methods. The article presents the results of a study of the properties (heat conductivity density, vapor permeability, water absorption) and application features (resistance to the effects of temperature, humidity, aggressive components contained in the air, that is, its high operational stability) of rolled non-cross-linked polyethylene foam when creating insulating sheets that protect snow from melting. Results. It was found that polyethylene foam in the insulating system maintains the stability of mechanical and thermophysical properties. Taking into account all the functional features of the implementation of insulation systems, the principles of protection and preservation (conservation) of snow cover have been developed, implemented on the mountain slopes and plateau of ski facilities. Rolls of foamed polyethylene were joined end-to-end and mechanically fixed. Conclusions. Thus, a seamless insulating coating was formed, covering the entire hillside — “thermal blanket”. The insulation system is operated during the off-season between March and September, during a period of stable positive temperatures.
