How Long is Aluminium Window Lifespan? (Kenya 2026 Durability Guide)
Aluminium windows typically last between 20 and 40 years, depending on material quality, installation standards, and environmental exposure. In Kenya, properly installed systems can exceed 25 years with minimal maintenance.
Unlike timber, aluminium does not rot, and unlike mild steel, it does not rust easily. Its durability comes from natural corrosion resistance and protective finishes such as powder coating or anodizing.
At Formlab Kenya, aluminium systems are engineered for long-term structural performance in both residential and commercial environments.
What Factors Affect Aluminium Window Lifespan?
The lifespan of aluminium windows is influenced by material quality, environmental exposure, installation workmanship, maintenance practices, and hardware durability.
- Aluminium profile grade (standard vs architectural grade)
- Surface finish (powder coating vs anodizing)
- Glass type (tempered or laminated safety glass)
- Quality of seals and gaskets
- Exposure to moisture, dust, and salt air
- Installation accuracy and alignment
