Abstract

Construction system consists of materials with different properties. The use of materials in the design should ensure maximum of its performance and its durability. The use of thermal insulation materials is an effective way to form the thermal envelope of a building, reducing energy costs and increasing the durability of building structures. The properties of materials are determined by their structure, which is formed in the process of technological influences. Formation of the insulating shell of oil and gas industry objects is possible only when considering the special features of the thermal insulation layer in the construction and the use of high-quality materials that retain their characteristics, both in the early stages of operation and throughout the calculation period. The first is achieved by competent design, the second the possibility of assessing the properties of thermal insulation (and predicting changes in these properties over time) directly in the construction site.The methodology for assessing the properties of insulating products includes two main components: testing facility and methodology for assessing operational stability. The methodology of conducting accelerated tests and prediction of durability is tested for mineral wool products of a layered, corrugated and volume-oriented structure. The test results give good convergence with the methods recommended by the building codes.
