Effectiveness of thermal insulation products is determined by a set of criteria that can be expressed in terms of energy costs: reduction of the cost of heating (the main criterion), energy consumption in the course of construction, energy consumption in the course of production of materials having pre-set properties, and service durability of the material.On the one hand, service durability (as a property) is generated in the course of material production, and on the other hand, it depends on the conditions that the material is exposed to in the course of any construction process. The same parameter affects energy-related criteria. Insulation replacement or unplanned repairs add supplementary energy costs.The manufacturing process of thermal insulation materials contemplates processing of a significant amount of non-renewable natural resources, namely, fuel combustion. Optimization of these costs is necessary and possible through appropriate organization of processes, including the process of heat treatment of products.Layered materials can improve the product performance and durability. Production and heat treatment of mineral fibers are the most energy-consuming steps of the mineral wool production. Optimization of these processes can involve significant economic effects.

Insulation is widely used in constructions of roofs, facades and fire protection. Using of dual-density allows to obtain not only a strong thermal insulation but also has a high operational stability. Product structutre is formed in the stage of mineral wool carpet and fixed during thermal processing. Manufacturing of dual-density products is based on the technological schemes of mineral wool production. Dual density slabs technology require the special complex located in the linear process flow after press unit and heat treatment camera. Units operate on lines Rockwool (in the cities of Zheleznodorozhniy, Vyborg and Elabuga) and are focused on making the roof and facade insulation with combination structure. Studying of factors influencing the production of dual density slabs process is based on a common methodology of technological analysis and methodology. Software system is developed to study processes. The complex provides individual activity of the experimenter and processing of the experimental results with the help of special computer programs developed at MSSU: “JE-STAT-15. Calculations and analysis of the factor space”, “JE-STAT-23.Construction of nonlinear models and solution interpolation and optimization problems”, “GJ-STAT-06.Processing and analytical optimization of the results of the experiment”. The experiment and processing of the results allowed to determine the degree of influence of each factor. Founded is that the greatest influence on the results have the following factors: density, binder content, fiber diameter, fiber length, degree of compaction two layers of carpet. It results in the nomogram for solving problems of interpretation and adaptation, optimization of process parameters.

Creating an effective insulation envelope of the building is possible only using high-quality materials, preserving their characteristics both in the early stages of operation, and for the whole billing period. It is an important opportunity to assess the thermal insulation properties and predict its changes over time directly in the conditions of the construction site. The products based on mineral fibers (rock and glass wool, basalt fiber) are the most widely used type of insulating materials in the domestic construction. Therefore, the operational stability valuation methods must be primarily created for this group of products. The methodology for assessing the thermal insulation properties includes two main components: testing equipment and methodology for assessing the operational stability. The authors tested the methodology of the accelerated testing and prediction of durability for mineral wool products of laminated, corrugated and volume-oriented structures. The test results give good convergence with the methods recommended by the building regulations. Application of thermal insulation materials are an effective way to form the thermal envelope of the building, reducing energy costs and increasing the durability of building structures. The material properties are determined by their structure, which is formed during the technological impacts.

The use of thermal insulation materials is an effective method to create an insulating envelope of a building, as well as to reduce energy costs and increase the durability of building structures. The properties of stone wool products and their operational durability is largely determined by the conditions of formation of the mineral wool carpet, uniform distribution of binder and its curing and the heat treatment conditions. Most domestic technologies are aimed at the production of mineral wool products with volume-oriented structure, which is formed using special units: spreader and corrugator placed in a production line. The next step to obtain the optimum structures is the production of dual density slabs. The denser upper layer receives mechanical loads caused by the operating conditions; the lower, less dense, but more thick layer performs the main function - insulation. The dual density slabs are produced on standard lines supplemented with a special unit, which is located in front of the heat treatment camera. Optimization of heat treatment parameters and prediction of the properties of materials is performed using software package.
