Roof sandwich panel
The ARPANEL D MiWo roof sandwich panel with a mineral wool core is primarily a board with excellent fire resistance parameters. The mineral wool core also guarantees very good thermal and acoustic insulation, durability and stiffness. Galvanized and coated steel cladding together with the structural and insulating core make the roof sandwich panels have high mechanical strength.
The ARPANEL D MiWo roof sandwich panel can be used wherever the requirements for fire resistance and acoustic insulation are stricter. It is used to cover the roofs of production and warehouse halls, industrial facilities, fire protection rooms, car showrooms and shopping malls.
