Metfiber Eco Wall HF

The Metfiber® Eco HF Wall panel with glass wool core and joint-geometry for hidden fixing fulfils all the requirements for non-combustible building materials and is excellently suited for both vertical and horizontal installation. The glass wool used in this product consists of 80% recycled material, thus contributing significantly to the saving of natural resources and making the product an ecological building material.

The deadweight of the panel is distinctly lower than that of conventional sandwich panels with rock wool insulation core, hence enabling an easier, faster installation and cost reduction, especially for longer panels.

For buildings exposed to high wind-suction, a 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 rock wool insulation core, it is possible to reach fire-safety, acoustic and thermal requirements at once without any visual impact.

Please have a look at our detailed technical manual for further information.

Colour & Coating

METCOLOR COATING SYSTEMS

STANDARD COATING FOR EXTERNAL APPLICATION
25μm POLYESTER

Corrosivity category RC3 in accordance with DIN EN 10169:2010-2
UV resistance category RUV2 in accordance with DIN EN 10169:2010-2
Temperature exposure -20° to 80°C
The well-proven polyester-coating is a modern and costeffective coating system, adapting well to different colour finishes. Polyester-coatings show good corrosion- and weather resistance under normal conditions for industrial application within the Central European region, which makes it the most frequently used coating system.

STANDARD COATING FOR INTERNAL APPLICATION
15 μm DU-POLYESTER

Corrosivity category RC2 in accordance with DIN EN 10169:2010-2
Temperature exposure -20° to 80°C
The polyester-thin-coating (standard colour shade similar to MC 9002) is suitable for conventional industrial buildings for indoor application in rooms with normal room climate and normal relative humidity. The colour shade may not be uniform due to the coating thickness.

25 μm OR 35 μm PVDF (POLYVINYLIDENFLUORIDE) - On request

Corrosivity category RC3 (25 μm) or RC4 (35 μm) in accordance with DIN EN 10169:2010-2
UV resistance category RUV4 in accordance with DIN EN 10169:2010-2
Temperature exposure -20° to 110°C
This coating shows optimal resistance against UV-radiation and weather and has good ductility. lt is suited particularly well for high requirements on the colour finish and has been found to be excellent in regions with difficult climatic conditions (e.g., 5-15 km from the sea).

Our recommendation for outdoors (indoors)

50 μm POLYAMIDE MODIFIED POLYURETHANE (PUR-PA) - On request

Corrosivity category RC5 in accordance with DIN EN
10169:2010-2
UV resistance category RUV4 in accordance with DIN EN
10169:2010-2
Temperature exposure -20° to 80°C
By using polyamide this coating system reaches a high surface hardness. lts visibly grained structure is particularly resistant to abrasion and ensures efficient protection against mechanical damage. lt is also widely resistant to strain by animals such as poultry, making it ideally apt for agricultural application. The flexibility and excellent resistance to UV radiation make this coating also suitable for outdoor installation.
