If you're considering HardiePlank wall cladding, longevity is likely one of your top concerns. So, how long does HardiePlank actually last? The simple answer: 50 years or more when properly installed and maintained.
This makes it one of the most durable cladding options on the market, far outlasting timber and even many uPVC alternatives.
Unlike wood, which is vulnerable to rot, and uPVC, which can crack over time, HardiePlank is made from fibre cement, a combination of Portland cement, sand, and cellulose fibres. This gives it exceptional resistance to weather, fire, and pests, ensuring a long lifespan with minimal maintenance.
What Factors Affect HardiePlank’s Lifespan?
✔ Material Quality
HardiePlank is engineered to be weather-resistant, fireproof, and impact-resistant, making it superior to many traditional cladding materials.
✔ Climate & Environmental Exposure
- In areas with heavy rain or humidity, HardiePlank resists moisture absorption, unlike timber cladding, which can rot.
- It performs well in coastal environments, where salt exposure can degrade metal cladding over time.
- HardiePlank is UV-resistant, meaning it won’t fade or weaken under direct sunlight like uPVC.
✔ Installation Quality
- A properly installed HardiePlank system will last decades, while poor installation can cause gaps or water ingress.
- It should be fixed onto a solid framework, with adequate drainage and ventilation to prevent any potential moisture build-up.
✔ Maintenance & Upkeep
- Minimal maintenance required—occasional cleaning and repainting (if not using pre-finished boards).
- ColorPlus® Technology boards come pre-finished with UV-resistant paint, meaning they won’t need repainting for at least 15 years.
How Does HardiePlank Compare to Other Cladding Materials?
| Cladding Type | Expected Lifespan | Maintenance | Weather & Fire Resistance |
|---|---|---|---|
| HardiePlank (Fibre Cement) | 50+ years | Low | Excellent |
| Timber Cladding | 20-40 years | High | Susceptible to moisture & pests |
| uPVC Cladding | 20-30 years | Low | Moderate resistance, can crack |
| Metal Cladding (Steel/Aluminium) | 40-60 years | Low | Excellent |
| Brick Cladding | 50-100 years | Very Low | Outstanding |
✔ HardiePlank outperforms timber and uPVC in lifespan, durability, and maintenance.
