The Monowall® panel with polyurethane insulation core is suitable for both vertical and horizontal installation. Its special surface profile facilitates the installation of the panel without the risk of bulging.  The appearance of the external side benefits distinctly from the screw head applied in the recess of the profile.

A non-displaceable longitudinal sealing strip produces a joint resistant to driving rain and wind. The organic coating of the steel sheet ensures efficient protection against all kinds of weather.

Additional coating systems are available for advanced application.

Reaction to Fire

Building material classified as B-s2,d0 flame-resistant according to DIN EN 13501-1

Thermal Conductivity

λ=0,024 W/m.K according to DIN 4108 and DIN EN 13165

The insulation values are regularly monitored by external bodies and may be applied without any further reduction.


Sound Insulation

Rw ≥ 25 dB


Corrosion Protection

  • Standard version with external sheet 25 μm polyester and internal sheet ≈15 μm thin coating (DU)
  • External sheet: category RC3; internal sheet: category RC2 (under the terms of DIN EN 10169)


External sheet: corrosivity category C3 corresponding to average duration of protection for urban and industrial environments with moderate exposure to sulphur dioxide.  

Internal sheet: corrosivity category C2 for dry indoor rooms and buildings with occasional minor condensation. Other coating systems are available for more sophisticated demands such as buildings near the sea, farm buildings with high ammonia exposure or moist rooms.

(Conditions of surroundings and corrosivity categories under the terms of DIN EN ISO 12944-2)

Standard lengths

> 2,00 m up to 25,00 m, greater lengths on request.
