## **Key Properties**

-   **Acoustic performance:** The panel is composed of a GMT substrate and [PET foam](https://www.bigbahn.de/pages/pet-foam-board) strips. The GMT substrate itself exhibits inherent sound absorption and noise reduction capabilities, while the physical structure of the PET foam strips further contributes to sound dissipation.
    
-   **Weight reduction:** The [GMT](https://www.bigbahn.de/pages/gmt-panels) base is approximately 50 % lighter than conventional timber. Combined with PET foam strips, this results in a significant reduction in vehicle or vessel load.
    
-   **Material safety (FST characteristics):** The PET foam component exhibits pronounced FST properties, namely: flame retardant, low smoke, and non‑toxic.
    
-   **Mechanical stability:** The material provides high mechanical strength, structural stability, water resistance, moisture resistance, and corrosion resistance, with low susceptibility to mould or decay.
    
-   **Aesthetic versatility:** The distinctive 3D linear profile enhances interior luxury and spatial depth in RV and yacht applications.
    
-   **Environmental regulation:** The panel facilitates ventilation, light transmission, and heat dissipation.

## **Product Classification (Surface Finishes)**

Based on surface finish, the 14mm Grille Panel is available in the following variants:

-   **Fire‑Resistant Grille (HPL‑Faced):** PET foam strips are surfaced with high‑pressure laminate (HPL). This configuration provides high resistance to scratching, abrasion, elevated temperatures, and fire, making it suitable for kitchen areas and public spaces.
    
-   **Aluminium‑Faced Grille:** PET foam strips are surfaced with aluminium skin. This construction provides high rigidity and a modern aesthetic, with enhanced impact resistance. It is recommended for wall and ceiling applications requiring an industrial style or maximum structural rigidity.

## **Application**

-   **Recreational Vehicles (RVs) and Yachts:** Interior sidewalls, ceilings, roof linings, and feature walls in sleeping areas.
    
-   **Acoustically sensitive spaces:** Mobile or fixed installations including home cinemas, broadcasting studios, and recording studios where noise control and sound quality are required.
    
-   **Public buildings:** Architectural decorative applications in high‑end hotels, commercial exhibition spaces, and residential fit‑outs.
    

## **Remarks**

-   **Installation requirements:** Although the panels are readily installable, substrate flatness shall be ensured for large‑area installations to maintain vertical alignment of the grille lines. On‑site cutting or modification is feasible; however, to guarantee final product quality and precision, priority should be given to the manufacturer's custom fabrication service based on customer drawings.
    
-   **Adhesive selection:** [PUR](https://www.bigbahn.de/pages/pur-flat-laminating-line) (polyurethane reactive) hot‑melt adhesive is recommended for surface lamination to ensure bond integrity under temperature fluctuations (e.g., in RVs exposed to summer solar loading).
    
-   **Maintenance and cleaning:** Dust accumulation between grille slats is expected. Regular cleaning using a soft brush or vacuum cleaner is recommended to preserve acoustic performance.
    
-   **Customisation tolerances:** For 14mm panels processed by [CNC](https://www.bigbahn.de/pages/cnc-processing) routing, allowance shall be made for load distribution between slats and substrate to ensure structural safety.
