Roof sandwich panel

ARPANEL D MiWo roof sandwich panel

The ARPANEL D MiWo roof sandwich panel with a mineral wool core is primarily a panel with excellent fire resistance properties. The mineral wool core also guarantees very good thermal and acoustic insulation, durability and rigidity. Galvanised and coated steel facing, together with a structural and insulating core, give the roof sandwich panels high mechanical strength.

The ARPANEL D MiWo roof sandwich panel is designed for wherever fire resistance and sound insulation requirements are stricter. It is used to cover the roofs of production and store buildings, industrial facilities, fire separation rooms, car showrooms or shopping malls.
