METFIBER ECO WALL SOUND
Metfiber® Eco Wall Sound with an insulation core of glass wool is THE solution for buildings with high requirements on sound insulation and sound absorption. The design of the perforated internal sheet improves room acoustics substantially. This system (patented by Metecno) uses a special fleece material as a trickle protection between the internal sheet and the glass wool core.
In addition to the outstanding acoustic properties, 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.
Generally used as ceiling or partition wall, Metfiber® Eco Wall Sound may also be used as external wall in specific cases, though it is generally not recommended to apply this panel in heated buildings or buildings with high moisture.

Corrosion protection
- Standard version with external steel sheet: 25 μm Polyester
- Tested according to DIN EN 10169: External sheet: Class RC3
Standard lengths
> 2,00 m up to 25,00 m, greater lengths on request.
Types of profiles
External/internal sheet
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.
