Abstract. The article analyzes the technology of installing railway depots with an external covering of sandwich panels that have a relatively low weight, high thermal insulation parameters, allow to produce yearround installation and do not require additional finishing, which considerably shortens the installation time; limited use of this technology in the installation of roofs of largespan buildings, and proposed a technology of mounting from collapsible panels, which allows to cover buildings with spans of 12 or more meters, which does not require a large number of freight, complex loadlifting and crane equipment, complex testing and ensuring the integrity of the surface , without bridges of cold.
Key words: sandwich panel, installation, technology, energysaving, performance.
