Choosing the right window material is one of the most important decisions in a home or apartment project. In India, the most common comparison homeowners make is uPVC windows vs aluminium windows.
Both materials have their advantages, but the better choice depends on climate, budget, maintenance expectations, and long-term comfort. This guide explains the real differences so you can make a practical decision.
1. Thermal & Sound Insulation
One of the biggest differences between uPVC and aluminium is insulation.
- uPVC windows are naturally non-conductive, meaning they do not easily transfer heat or cold.
- Aluminium windows are metal and conduct heat quickly unless special thermal break systems are used.
In Indian conditions:
- uPVC performs better for heat control and noise reduction
- Aluminium without thermal break allows heat transfer, especially in summer
👉 For homes near roads, apartments, and hot cities, uPVC offers better comfort.
2. Maintenance & Durability
Maintenance cost over 10–20 years matters more than initial price.
- uPVC does not rust, corrode, or need repainting
- Aluminium may corrode near coastal areas and requires surface treatment
uPVC windows:
- Wash with water
- No repainting
- No termite issues
Aluminium windows:
- May require repainting or refinishing
- Hardware wear can be higher if insulation is poor
3. Strength & Design Flexibility
Aluminium is naturally strong and allows very slim frames, which is useful for:
- Very large glass panels
- Commercial buildings
- Modern façade designs
uPVC, however:
- Uses steel reinforcement inside profiles
- Is strong enough for most residential openings
- Offers excellent sealing
For homes and apartments, uPVC strength is more than sufficient.
4. Cost Comparison in India
In most Indian cities:
- uPVC windows price: ₹275 – ₹850 per sq ft
- Aluminium windows price: ₹400 – ₹1,200+ per sq ft
High-quality aluminium systems with thermal breaks can be significantly more expensive than uPVC.
👉 For most homeowners, uPVC offers better value for money.
5. Which One Should You Choose?
Choose uPVC windows if you want:
- Better insulation
- Lower maintenance
- Noise & dust reduction
- Long-term value
Choose aluminium windows if you want:
- Ultra-slim profiles
- Very large glass spans
- Commercial or façade applications
Final Verdict
For most Indian homes, uPVC windows are the more practical and comfortable choice, especially in cities with heat, noise, and dust.
