Humidity resistance is a critical factor in building materials, especially in regions with variable climate conditions.
Aluminum honeycomb
- Non-porous metallic structure
- Zero moisture absorption
- No swelling or deformation
- Resistant to mold and biological growth
Paper honeycomb
- Hygroscopic fiber structure
- Absorbs atmospheric moisture
- Potential swelling and strength reduction
- Risk of mold in poorly ventilated environments
Environmental engineering perspective
In high humidity conditions (>70% RH), paper honeycomb may experience:
- Dimensional instability
- Reduced compressive strength
- Edge delamination over time
Aluminum remains unaffected, making it suitable for:
- Coastal buildings
- Bathrooms (non-direct water exposure systems)
- Underground or semi-enclosed environments
Conclusion
Aluminum honeycomb provides industrial-grade environmental stability, while paper honeycomb is limited to controlled indoor environments.
