BIGBAHN 14mm Grille Panel – Lightweight Composite Material Combining Aesthetic Design with Acoustic Performance.

Although the source documentation primarily references the 12mm specification, the Grille Panel supports extensive customisation in thickness and dimensions.

Core Technical Specifications

Parameter	Specification
Structural composition	GMT (Glass Mat Thermoplastic) substrate as base layer, with PET foam strips (slats) bonded to the surface
Standard dimensions	2440 × 600 mm or 2440 × 1220 mm
Thickness series	Standard thickness: 12 mm; alternative thicknesses including 14 mm are available upon request
Customisation	Slat width, spacing, and surface finishes can be tailored to design requirements
Emission class	E0 / ENF (no formaldehyde added)

Key Properties

Acoustic performance: The panel is composed of a GMT substrate and PET foam 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 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 (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 routing, allowance shall be made for load distribution between slats and substrate to ensure structural safety.

Frequently Asked Questions

What is BIGBAHN 14 mm Grille Panel?

It is a grille‑style panel product listed by BIGBAHN under their Grille Panel and RV categories, indicating use as a ventilated or slatted panel in vehicle interiors. our product suggests a composite structure (GMT plywood foam for RV) combining plywood and foam to keep weight low while providing stiffness and a grille appearance.

What are the standard dimensions?

BIGBAHN’s Grille Panel collection states standard sizes of 2440 mm × 600 mm as the primary dimensions offered.

Can the panels be customized?

BIGBAHN notes that the grille panels are available in standard dimensions but can be customized in terms of sizing to suit specific projects. typical queries include custom lengths for RV ceiling runs, narrower widths for cabinet fronts, or special layout and cut‑out patterns.

What thickness and construction are used?

The product listing refers to “14 mm Grille Panel,” which indicates a 14 mm overall thickness, likely based on a composite or plywood‑foam construction for RV use.
BIGBAHN promotes lightweight structural composite panels in their plywood collection, with densities as low as 320 kg/m³ and up to 40% weight reduction at similar strength.

What is it used for in RVs and interiors?

Grille panels are typically searched for as decorative slatted ceilings, wall features, room dividers, or fronts for storage spaces where airflow and aesthetics both matter.

How heavy is a 14 mm Grille Panel?

BIGBAHN’s lightweight composite messaging suggests that grille panels are designed to have lower density than solid plywood, reducing overall weight.

How are BIGBAHN Grille Panels installed?

General grille and panel installation guides emphasize identifying the panel and hardware, positioning, adhesive tape or mechanical fixings, and proper alignment for top and side panels.

What finishes and styles are available?

BIGBAHN’s grille panel collection is described as stylish, durable, and versatile, implying different surface finishes or colors to match RV interiors.

Are the panels compatible with other BIGBAHN products?

BIGBAHN groups Grille Panels alongside lightweight plywood, laminate panels, PET foam panels, and curved panels, encouraging integrated use in one build system.

Are there fire or acoustic properties?

Yes.

The BIGBAHN Grille Panel exhibits both fire‑retardant properties and acoustic absorption performance. The panel is composed of a GMT (Glass Mat Thermoplastic) substrate and PET foam strips. The GMT substrate itself possesses inherent sound absorption and noise reduction characteristics, while the physical structure of the PET foam strips further contributes to sound dissipation.

Can the panels be cut or modified on site?

On‑site cutting or modification of the BIGBAHN Grille Panel is feasible. However, to ensure final product quality and dimensional accuracy, priority should be given to the manufacturer's custom fabrication service based on customer drawings.

In cases where the substrate is exposed at cut edges, the application of edge banding supplied by the manufacturer (e.g., flat or T‑profile edge banding) is recommended to maintain aesthetic appearance and moisture resistance.
