Depending on the needs of the building that you are going to build, you can choose one of the three models of roof sandwich panels. Mineral rock fiber core sandwich panels, oriented perpendicularly to the metal panels, are ideal for buildings with a high fire risk. The PUR or PIR foam core sandwich panels, having one of the lowest thermal conductivity, help to maintain an efficient conservation of the temperature, facilitating easy maintenance of controlled temperature environments. If you have a low budget then you can opt for roof sandwich panels with ESP polystyrene core.
