Bali Hotel WPC Wall Panel Renovation: 14-Month Performance in 85% Humidity

Project Background

A boutique hotel in Bali, Indonesia, required a wall cladding solution for its pool area and surrounding spaces. The hotel's previous hardwood wall panels required sanding and resealing every six months due to the tropical climate's high humidity and frequent water exposure.

The project team sought a material that could withstand Bali's year-round humidity (80-88%) and temperatures (24-32°C) without the ongoing maintenance burden of traditional wood.

Challenges

• High humidity — 80-88% RH year-round, causing traditional wood to swell, warp, and develop mold
• Frequent water exposure — pool area environment with constant moisture and splashing
• Maintenance burden — previous hardwood required sanding and sealing every 6 months
• Aesthetic consistency — the hotel needed a natural wood look that would remain uniform across the installation

Solution

Necowood 360° Shield™ ASA/PVC co-extruded WPC wall panels were selected for their moisture resistance, durability, and zero-maintenance properties. The ASA cap layer provides protection against UV degradation and moisture absorption, while the PVC core ensures dimensional stability in high-humidity conditions.

The panels were installed in March 2025 around the hotel's pool area and adjacent wall surfaces.

Product Used — Necowood 360° Shield™ WPC Wall Panels

• ASA/PVC co-extruded structure — weather-resistant cap layer bonded to a stable core
• Teak finish — warm wood tone suitable for tropical resort aesthetics
• Zero maintenance — no sanding, sealing, or staining required
• Moisture resistant — designed for high-humidity environments

Results — 14-Month Performance Review

As of May 2026, the installation has been in service for 14 months. The hotel maintenance team has reported:

• Zero mold growth — no visible mold or mildew on any panel surface
• Zero swelling or warping — panels remain dimensionally stable despite 80-88% humidity
• Zero color change — no fading or discoloration from UV exposure
• Zero maintenance required — no sanding, sealing, or refinishing needed

Key Takeaways

• WPC performs in tropical climates — 14 months in 80-88% humidity with zero degradation
• Zero maintenance delivers cost savings — eliminates recurring sanding and sealing costs
• ASA co-extrusion provides durability — protects against moisture, UV, and mold
• Natural wood aesthetic without the upkeep — suitable for hospitality environments
