The Superwall® HF sandwich panel with a micro-profiled external steel sheet, a non-combustible mineral wool core and a joint-geometry for hidden fixing is suited best to meet today’s sophisticated requirements for high-quality façades. The panels can be placed vertically or horizontally and - depending on the insulation thickness - may reach a fire resistance up to 90 minutes.

Additionally, Superwall® HF panels show excellent acoustic insulation behaviour.

For buildings exposed to high wind-suction, horizontal single-span installation is recommended, so possibly needed visible fixing-screws may be covered by pilaster profiles.

Due to the large number of combinations with other panels from our portfolio with polyurethane or glass wool insulation core, it is possible to reach fire-safety, acoustic and thermal requirements at once without any visual impact.

Thermal Conductivity

λ=0,044 W/m.K under the terms of 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 ≥ 30 dB

Corrosion Protection

  • Standard version with external and internal steel sheet of 25 μm polyester
  • External and internal steel sheet: category RC3 (under the terms of DIN EN 10169)
External sheet: corrosive category C3 corresponding to average duration of protection for urban and industrial environments with moderate exposure to sulphur dioxide
Internal sheet: corrosivity category C3 for rooms with high humidity with moderate strain, i.e. food production, laundries, breweries and dairy factories. 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.
