Ceiling Treatments

Polyester fiber acoustic panelsare installed in RVs primarily viaadhesive bondingusingstructural adhesive.

They serve asdecorative wall panelingand are also widely applied inceiling headliners.

BIGBAHN polyester fiber acoustic panels meet the E1 grade requirement under national standard GB18580‑2001.
Formaldehyde emission is measured at 0.05 mg/L (or 0.05 mg/m³), well below the E1 limit of ≤1.5 mg/L.

While BIGBAHN’s core wood‑based plywood panels typically achieve the stricter ENF or E0 grades, the polyester fiber acoustic panels are clearly rated E1 – and the actual test values are extremely low, ensuring healthy interior air quality for RV cabins.

They are primarily used for RV sidewall decoration and also widely applied in ceiling headliners.

Key material advantages include:

• Lightweight
• Excellent mechanical performance (high toughness, impact resistance, tear resistance)
• Large panel dimensions (e.g., 9×1220×2440 mm)

These features enable easy installation. The panels are typically installed via adhesive bonding using structural adhesive.

Additionally, grille panels (composed of a GMT base panel and PET foam slats), which also provide excellent sound absorption and noise reduction, offer the same easy‑to‑install characteristics, making them ideal for decorative and functional covering in RV interiors.

The primary options include Polyester Fiber Acoustic Panels, GMT (Glass-mat reinforced Thermoplastic) Panels, PET Foam Panels, and Grille Panels.

For a more traditional look with extreme weight savings, AeroTek composite panels or lightweight plywood with OPP film are also used.

These panels are highly effective as sound absorbers, with a noise reduction coefficient (NRC) between 0.8 and 1.10.

They also provide thermal insulation, are uniform and tough, and are exceptionally lightweight, which is critical for reducing the vehicle's upper weight.

Unlike wood panels that require screws, polyester panels are installed using adhesives, specifically structural glue.

Because they are lightweight and do not have "nail-holding" requirements, this simplifies the installation process and reduces the risk of mechanical fasteners loosening over time.

Yes.

Polyester Fiber panels are designed with safety in mind; unlike brittle materials like gypsum or cement boards, they do not produce sharp fragments or splinters if they are impacted or fall, eliminating potential hazards to passengers.

GMT Panels serve as a high-tech substitute for aluminum and plywood. They are 50% lighter than wood, offer excellent noise absorption, and possess high tensile strength.

They are also resistant to mold, mildew, rot, and warping, ensuring long-term structural integrity.

Yes, PET Foam Panels are commonly used for automotive headliner interiors and rail roof panels.

They are 100% recyclable, have high thermal stability, and meet FST (Flame retardant, low smoke, non-toxic) safety standards.
