When it comes to choosing aluminium windows in South India, whether for a modern Chennai apartment, a traditional Kerala nalukettu, or a coastal villa in Mangalore, the wrong decision can mean years of maintenance headaches. High humidity, salty coastal winds, and intense sun are part of everyday life here, and not all materials can handle it. That’s why aluminium windows have become the smart choice for both fabricators and homeowners in this region. At GREFET, we design and engineer aluminium systems specifically to perform in South India’s unique climate and architectural settings.
Why Aluminium Works Best in South India
Unlike timber, which swells in humidity, or uPVC, which can warp in the heat, aluminium offers:
- High corrosion resistance with proper powder-coating or anodizing
- Dimensional stability in extreme temperatures
- Slim profiles for maximum light and ventilation
- Long-term finish retention even in salty air
Example: In a Chennai high-rise near the sea, GREFET’s marine-grade powder-coated aluminium maintained its colour and performance for over a decade, no peeling, no rust.
Matching Aluminium Finishes with South Indian Architecture
One of aluminium’s biggest advantages is the range of finishes it offers. This makes it easy to match with diverse South Indian styles:
1. Kerala Traditional Homes
- Finish Options: Woodgrain (Teak, Walnut), Bronze Anodized
- Why: Complements sloped tiled roofs, wooden columns, and carved verandas.
- Design Tip: Use casement or sliding windows with mesh sliders to suit the tropical climate.

2. Tamil Nadu Coastal Villas
- Finish Options: Textured Charcoal, Matte Anthracite, Satin Grey
- Why: These resist corrosion from salty sea breeze while giving a contemporary edge.
- Design Tip: Opt for double-glazed sliders to improve thermal and acoustic performance.

- Design Tip: Use corner sliders or floor-to-ceiling fixed glazing for open-plan layouts.
4. Chettinad Heritage Residences
- Finish Options: Mahogany Woodgrain, Earth Brown Powder-Coat
- Why: Mimics the warmth of wood while offering better durability in heat.
- Design Tip: Choose arched aluminium frames to respect heritage aesthetics.
Key Considerations for Fabricators in South India
If you’re a fabricator, your choice of systems and finishes directly affects your client’s satisfaction, and your reputation.
1. Choose Marine-Grade Coatings
Even inland cities like Coimbatore and Mysuru face high humidity. Use powder-coated finishes that meet QUALICOAT or AAMA standards.
2. Focus on Water Drainage
System designs with integrated drainage channels prevent water ingress during monsoons.
3. Offer Climate-Specific Options
Clients in Kochi may need corrosion resistance first, while Bengaluru homeowners may prioritise thermal performance.
4. Educate Clients About Long-Term Value
Many buyers compare only upfront costs. Show them how GREFET systems outperform cheaper, non-system aluminium in lifespan and maintenance savings.
