CARAVAN SALON 2026 Lattice Panels: BIGBAHN 13A94

BIGBAHN GmbH exhibits at Hall 13, Booth A94 (13A94)

CARAVAN SALON Düsseldorf 2026 runs 28 August – 6 September 2026 at Messe Düsseldorf (09:00–18:00 daily, 10 trade days), drawing 250,000+ visitors and 600+ exhibitors — Europe's flagship trade fair for motorhomes, caravans and camper vans.

What Are RV Lattice Panels? Six Functions, Four Base Materials

A RV lattice panel (also called grille panel or ventilation grille) is a perforated/openwork decorative or functional panel with 30%–70% open area, serving six core functions in caravan and motorhome interiors:

• cabinet door ventilation to prevent mould and odour; 
• acoustic-transparent faces for speakers and HVAC vents; 
• heat-dissipation back panels for fridges and gas appliances; 
• splash-proof shields for bathroom and kitchen modules; 
• storage compartment dividers and decorative slats; 
• dashboard ventilation layers in camper vans.

The four base material families are HPL (high-pressure laminate) / compact laminate, lightweight plywood, PET foam board, and GMT panel — the first two dominate furniture and interior trim, while the latter two target structural and floor/wall-base applications.

Key specifications are open area ratio, formaldehyde emission grade, Taber abrasion cycles, and thickness swelling (TS).

Open Area vs Acoustic Performance

Higher open area is not always better. 

Empirically:

• cabinet-door ventilation uses 30%–40% (balances airflow and privacy); 
• speaker grilles use 50%–60% (preserves high-frequency transmission, <1 dB insertion loss at 4 kHz); 
• fridge rear panels use 60%–70% (maximises natural convection).

Acoustic testing follows ISO 354 (reverberation room) and EN ISO 10534-2 (impedance tube). OEMs should request 1/3-octave insertion-loss curves from suppliers.

Manufacturing Process and Material Mechanics of Lattice Panels

Three dominant forming processes exist:

• CNC routing: ideal for HPL/compact laminate, supports any pattern
• laser cutting: ideal for lightweight plywood and PET foam board burr-free edges
• press moulding: the GMT mainstream process, ideal for high-consistency industrial batches

BIGBAHN operates CNC machining centres and laser-cutting lines across its German and Chinese factories, with single-line daily capacity of 3 000–5 000 standard 600 × 600 mm panels — accommodating orders from 50-piece prototyping runs to 100 000-piece annual OEM programmes.

Mechanically, lattice panels have 20%–40% lower flexural strength than solid panels of the same thickness, but higher specific strength (strength-to-weight), making them a key lightweighting material for RV applications.

BIGBAHN's ENF-grade grille panels achieve a 0.3 MPa flexural strength at 1.0 g/cm³ density, delivering 18%–25% weight savings vs equivalent solid-wood grilles. Note that road-vehicle interior materials must also pass ECE R118 Annex 7–9 burning tests (melting drip, vertical burn, smoke density). The R118 Rev. 03 (2023) amendment extended Annex 9 smoke toxicity to multi-material composite interiors, capping CIT ≤ 30 (Source: UNECE, ECE R118 Rev. 03, 2023).

How Dual-Factory Sourcing Affects EU OEM Lead Times

Six typical RV lattice-panel applications: 

1. slatted wall panels: decorative wall strips and upholstery dividers;
2. cabinet door grilles: wardrobe, shoe cabinet, gas-locker doors;
3. speaker & HVAC grilles: acoustic-transparent + visual continuity;
4. appliance rear panels: passive heat dissipation for fridges and gas appliances;
5. bathroom/kitchen splash shields: water-resistant + breathable; 
6. camper van under-bed ventilation layers: structural airflow; 

OEM material/open-area pairing by scenario:

• decorative strips use 20%–35% open area + HPL;
• cabinet doors 35%–50% + lightweight plywood + HPL overlay;
• speaker grilles 50%–65% + 1.0–1.2 mm HPL;
• fridge backs 60%–70% + GMT panel;
• bathroom splash shields 40%–55% + PET foam board;
• van dashboards 50%–60% + GMT;
