The sandwich panel is so called because of its structure. Such panels represent a three-layer structure consisting of two solid surfaces between which there is a layer of heat-insulating material. Today, the most optimal material for a sandwich panel is galvanized steel, which has a high resistance to mechanical stress and a relatively low price. Mineral wool or expanded polystyrene (polystyrene) is used as insulation.
Sandwich panels are divided into wall and roof panels. Roofing panels are subject to increased requirements for corrosion resistance and water resistance. In developed countries, roofing panels have recently begun to be equipped with photovoltaic cells, which make it possible to receive electricity from sunlight. In this case, the photocell is placed under the fiberglass layer and thus remains protected from the effects of atmospheric precipitation.
In construction, galvanized steel sandwich panels are used for the installation of pre-fabricated buildings and structures. In industrial construction, they are used to build various production workshops, car washes and service stations, shopping centers and shops, as well as various prefabricated objects. In civil (residential) construction, a sandwich panel is the most common roofing element that allows you to obtain a high-quality roof with high thermal insulation properties.
It is best to entrust the installation of sandwich panels to a specialized organization such as DNSstroy. This company specializes in the production, assembly and installation of sandwich panels at objects of any complexity. Possessing extensive experience in working with pre-fabricated structures, the company DNStroy will perform the assembly and installation of wall and roof panels with high quality and in the shortest possible time.
