Which is Better for Nepal?
Our Recommendation: Aluminium Windows
For most homes in Nepal, aluminium windows are the practical choice. Here's why:
- 1. Repair accessibility: Aluminium parts are available in every locality. UPVC repairs often require importing parts or waiting weeks.
- 2. Skilled technicians: Thousands of aluminium workers in Kathmandu. UPVC specialists are rare.
- 3. Cost-effective: 30-50% cheaper initially, and repairs are affordable.
- 4. Climate suitable: Nepal doesn't have extreme cold like Europe where UPVC shines. Aluminium handles our climate well.
- 5. Earthquake resilience: Aluminium is more flexible and handles structural movement better.
When to Choose UPVC:
- Rooms with air conditioning (better insulation saves electricity)
- High-rise buildings in noisy areas (better soundproofing)
- Premium apartments/homes with higher budgets
- Buildings near highways or airports
Cost Comparison for a Typical Home
