Wall sandwich panel

ARPANEL S MiWo MXL wall sandwich panels

The ARPANEL S MiWo and S MiWo MXL wall sandwich panel is made of two claddings (internal and external) made of galvanized and coated steel sheet and a structural and insulating core made of mineral wool. The core provides the board with excellent fire-fighting properties as well as thermal and acoustic parameters, and in combination with the highest quality galvanized steel sheet, it is responsible for high mechanical strength and durability, which translates into long-term service life of the building made with the use of ARPANEL sandwich panels. The structure of the sandwich panels enables quick and easy assembly both in a horizontal and vertical arrangement. All these factors make ARPANEL S MiWo and S MiWo MXL wall sandwich panels meet the highest European standards. They are ideal for facilities, where fire safety is very important, such as external and internal fire partitions. On the other hand, the ARPANEL S MiWo MXL sandwich panels with increased core density are an ideal solution when it is required to use products with increased load-bearing capacity and mechanical strength, in order to avoid the need to install additional structural elements.
