A sandwich panel is any structure made of three layers: a low-density core, and a thin skin-layer bonded to each side. Sandwich panels are used in applications where a combination of high structural rigidity and low weight is required. Sandwich Panel is the only material that allows disassembling the construction and erecting it somewhere else. At the same time due to the light weight of Sandwich Panels, transportation could be relatively cheap. The working life of Sandwich Panels on average is about 50 years. Besides, since the building of Sandwich Panels is an assembled prefabrication, any damaged element of the construction could be easily replaced. It meets the sanitary and environmental standards, including standards of housing construction; another property is excellent sound insulation.
