Hipertec® Wall Sound is a sandwich panel with an insulation core of mineral wool and steel cover sheets, the internal sheet being perforated. This panel is perfectly apt for buildings with high requirements on sound insulation and sound absorption. The design of the internal sheet improves room acoustics substantially. This system (patented by Metecno) uses a special fleece material as trickle protection between the internal sheet and the mineral wool core.

Generally being used as a ceiling or partition wall, Hipertec® Wall Sound may also be used as an external wall in specific cases, though it is generally not recommended to apply this panel in heated buildings or buildings with high moisture.

For additional information, please have a look at our detailed technical manual.

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.

Approvals & Certificates

Since this product has a perforated internal steel sheet, it does not apply to the EU norm for sandwich panels (see DIN EN 14509:2013; Section 1 – Field of Application). For that, in Germany, this panel is declared an unregulated material and has no Declaration of Performance (according to the Construction Products Regulation), no CE label and no technical approval. For the application of this panel as a façade contact us or check with your local building authority.

Packaging

External sheets provided with removable protective foil, panel-packages wrapped with banded plastic foil to protect from soiling. Also, package weights of max. 2,5 t or 1,5 t are available on request.

Container shipment

On request, we provide container packaging apt for oversea shipping. The panels will be stored in containers of 20 feet (6,096 m) or 40 feet (12,192 m), including an unloading system for easy unloading of the packages at their destination.
