Modern Thermal Insulation and Sound Insulation Materials

Abstract

AbstractIn the introduction of the work history was given, the importance of the application of thermal insulation and sound insulating materials in construction, the transfer of heat and sound, and the mechanisms of thermal and sound insulation. The reasons for the use of thermal and sound insulation and the consequences of insufficient heat and sound insulation are given. Heat and sound transfer and three modes of heat transfer and sound transmission in open and indoor spaces are described. In the continuation of the work, the division of thermal insulation materials was given based on formation: natural thermal insulation materials; synthetic thermal insulation materials; products of mineral origin; thermal insulation concretes and mortars and polyurethanes, and what they are made of, thereby distinguishing them and where they are used. The next chapter is the type of sound insulation material, where the characteristics, advantages, and disadvantages of the most common sound insulators are listed. The accent of the work is given to development trends and the most important modern materials for thermal insulation and sound insulation. Development trends state how thermal insulation materials are developed, according to what and what they are trying to improve. The most important modern materials for thermal insulation are singled out: aerogel, foam glass, Rockpanel plates, aerogel university of Singapore (NUS), and Bronya thermal insulation coatings with all their pros and cons. Similarly, innovative sound insulation products are listed below: sound insulation “Shumanet”; silka calcium silicate blocks; Green Glue sound insulation, and eco wool insulation. At the end of the paper, a conclusion was made as a reflection on the entire work.KeywordsHeat conductivityHeraclite platesExpanded polystyrene (EPS)Extruded polystyrene (XPS)Glass woolStone woolThermal insulation concretesThermal insulation mortarsPolyurethanesAerogelFoam glassRockpanel plates
