Coating
Optimize your roof and wall construction according to the respective stress in the interior and exterior. The properties of our construction elements can be optimally adapted to their subsequent use by means of different organic coatings, such as synthetic resin stoving enamels, plastic dispersions or decorative foils.

Condensate storage coating
FALK Salzgitter GmbH provides effective moisture protection for exterior metal structures enclosing rooms by means of a condensate storage coating (fleece coating).
In a certain indoor climate with a corresponding indoor temperature ti and a different outdoor temperature ta, there is a risk of condensation forming on metal roofs and walls without thermal insulation or with insufficient thermal insulation. This applies in particular to single-shell constructions of water-bearing shells.
Damage caused by dripping condensate to the structure and stored goods can be reduced to a minimum by a fleece coating and careful planning and execution. In order to avoid a so-called wicking effect as well as further damage, the following design details must be observed:
- In transverse joint areas of trapezoidal sheets, the fleece coating on the underside of the sheet above must be removed.
- Adequate ventilation must always be ensured by design.
In the eaves area, the fleece coating must be removed over a length of 100 mm across the entire construction width of the profile or sealed accordingly with capillary-blocking materials.

Sound attenuation
To reduce the noise level in workrooms or to improve speech intelligibility, the reverberation time of a room must be reduced. For this purpose, perforated acoustic elements can be backed with sound-absorbing acoustic fleece. The absorption coefficients measured according to EN ISO 354 range between approx. 0.2 and 0.7 depending on the frequency.
On the other hand, visco-elastic coatings are required to reduce the sound radiation of rain noise to the outside (e.g. in single-skin trapezoidal sheet metal roofs).

Colors
Building elements made of FolaSal® for roofs and walls combine effective corrosion protection with an attractive appearance. The individual combination of different colorings enables the realisation of distinctive roof and facade constructions.
We strike your tone
Based on the RAL color card system, you can choose your individual color tone from 99 current shades offered by FALK Salzgitter GmbH. Please note that the colors shown in the table are for orientation purposes only, as a binding reproduction of the original RAL color shades is not technically possible.
For information on availability from stock, please contact our sales staff.
The respective coatings can be found in the list and of course special colors, for example according to the NCS colour chart, are also possible on request.
For an exact color match with regard to individual color perception, color rendering of metallic surfaces or matching with existing, otherwise colored products, please request a corresponding sample.
For technical reasons, color uniformity cannot be guaranteed for coatings ≤ 15 my.
