Many of our compatriots will be surprised by the fact that the sandwich panels begin their story in 1930, when an American engineer first introduced them into construction when working on the Unsonian project. Sandwich panels are a building material consisting of three layers: metal, insulation, metal. The layers are firmly interconnected thanks to the pressing method at high temperature. Sandwich Punels allow reducing the construction of many buildings, since they do not require a heavy and powerful foundation, or finishing the walls of the building, since they are supplied from the factory already painted in the required color.
You can build buildings from sandwich panels at any time of the year, and the construction more resembles the assembly of the designer, since the necessary kit for the building is ordered immediately at the factory and at the facility it remains only to assemble the elements together, constructing the structure. Since the terms of such construction are very short-lived, the cost of a building from sandwich panels is today the lowest among other materials for the construction of buildings (concrete, brick, wood, etc. D.). But the sandwich panels have two significant drawbacks-relatively low strength and freezing in places of seams at low temperatures.
