ENERGY-EFFICIENT INSULATION SYSTEMS FOR LOW-RISE BUILDINGS

Statement of the problem. Low-rise construction is characterized by a relatively low cost and a possibility of forming effective insulating structure shells. Frames and massive walls are used as load-bearing structures, it is also possible to use concrete. Taking into account the current realities, the most relevant is the orientation of systems to the use of domestic materials including those capable of functioning effectively in harsh climatic conditions. Results. It was established that the properties of polyethylene foam and products based on it make it possible to recommend this material both in facade and roof insulation systems as well as in those in contact with the ground. It was found out that polyethylene foam causes almost no changes in the properties under freezing conditions down to minus 70 °C and in the range of sign-variable temperatures from -60 to +70 °C. With prolonged contact with water or water-saturated soil, the properties of the material are also stable. Conclusion. The use of rolled polyethylene foam is promising both in terms of the properties of the material itself and in view of the possibility of forming seamless insulating shells. The formation of seamless insulating shells creates practically impenetrable heat-vapor- and water-insulating barriers along the perimeter of the insulated object. The study of the properties of polyethylene foam in various operating conditions and insulation systems was the goal of the research described in the article. Methods approved by domestic standards were adopted as the basis for the research.
