Thermal insulation materials.
Thermal insulation materials are structural elements that help reduce heat. All of them are divided into organic and inorganic. Inorganic heat -insulating materials include mineral wool. Along with many positive properties, somehow good heat resistance, lightness and porosity, it has several negative features-it has low strength characteristics and very hydrophilic (that is, it is able to absorb water, due to which it loses its thermal insulation properties). Therefore, mandatory protection of a vapor barrier and waterproofing film will include the features of the installation of such thermal insulation material. The most popular among inorganic heat -insulating materials: basalt cotton wool and glass wool.
Thermal insulation finds its application everywhere where there is a need to reduce heat transfer.
In the construction of residential buildings and structures, thermal insulation is used for both external and internal insulation of the walls of buildings, floors and roofs. This helps to reduce energy consumption for heating and air conditioning.
For thermal insulation of the walls of residential buildings, such types of thermal insulation as polystyrene foam and glass wool are mainly used.
For technical insulation, foamed polyethylene (in the form of tubes and sheets) or basalt wool is used.
A special type of thermal insulation – reflective, is made of foamed polyethylene and aluminum foil. Such thermal insulation is used in residential and industrial buildings, but is mainly used to insulate baths and saunas, refrigeration chambers and other technical equipment.
For insulation of facades of residential buildings, stone or glass cotton wool, polystyrene foam or mineral wool is used. Currently, a special three-layer design is increasingly popular-a sandwich panel. It has good heat -insulating properties and is also resistant to water, which allows you to successfully use it for external work without additional protection.
