10 Things to Know About Aluminium Windows

When you’re building or renovating your dream home, windows play a bigger role than most people realise. They shape how light, air, and sound interact with your interiors. Among all materials available today, aluminium has become the preferred choice for modern homeowners and architects alike. Whether it’s rainproof windows for monsoon protection, anti-dust windows for city living, or luxury aluminium windows that elevate aesthetics, this material offers a balance of beauty, strength, and long-term performance.

Eternia, from Hindalco, an Aditya Birla Group company, has taken aluminium innovation to a new level with Duranium, a proprietary alloy 40% stronger than conventional aluminium. Eternia’s products combine strength, sleek design, and durability to meet the specific needs of Indian homes. Before you choose, here are ten things you should know about aluminium for windows, especially if you want your investment to last for decades.

What are the 10 Essential Things to Know About Aluminium Windows?

1. Aluminium Windows Are Built to Last

Unlike wood that swells or steel that rusts, aluminium is resistant to moisture and corrosion. This makes it ideal for Indian weather, from humid coastal regions to dry northern climates. Eternia’s aluminium frames stay sturdy and elegant for years, making them one of the most reliable materials for home construction.

2. Slim Aluminium Windows Offer Wider Views

Homeowners today love open, airy interiors, and slim aluminium windows make that possible. Thanks to the strength of Duranium, Eternia can create ultra-slender profiles that hold large glass panes securely. These sleek frames maximise natural light and provide uninterrupted outdoor views without compromising safety or structural integrity.

3. Aluminium Is Ideal for Rain-Proof Windows

Heavy monsoon rains can be challenging for most materials, but rainproof windows made of aluminium perform exceptionally well. Eternia’s windows are WiWA-certified for water tightness up to 750 Pa, meaning they keep interiors dry even during intense downpours. High-quality EPDM gaskets ensure that no water seeps through joints, maintaining both comfort and cleanliness indoors.

4. Aluminium Windows Keep Dust Outside

City homes often struggle with dust infiltration, especially near busy roads or industrial areas. Eternia’s anti-dust windows are designed with airtight seals and precision-engineered joints that minimise external particles. With an air sealing performance of up to 600 Pa, these windows help maintain cleaner interiors and reduce the frequency of maintenance, a significant benefit for urban homeowners.

5. They Are a Mark of Modern Luxury

Sleek, strong, and available in a range of finishes, luxury aluminium windows are a statement feature in contemporary architecture. Eternia offers a variety of design options and frame finishes, ranging from metallic shades like Slate Grey and Night Black to warm wood tones such as Oak or Walnut. Whether you prefer minimalist décor or rich elegance, aluminium blends effortlessly with every style.

6. Aluminium Windows Are Highly Sustainable

One of the most overlooked qualities of aluminium is its sustainability. Aluminium can be recycled endlessly without losing strength, making it an eco-friendly choice. Eternia’s Duranium alloy, developed by Hindalco, aligns perfectly with global green-building principles, combining durability with environmental responsibility.

7. They Perform Exceptionally Against the Elements

Aluminium frames are not just about looks, they’re engineered for performance. Eternia’s windows are tested under the WiWA (Wind, Water, Air) framework, ensuring high protection levels against India’s climatic extremes:

• Wind Resistance: Withstands pressures of up to 2.75 kPa, making it ideal for high-rise apartments and cyclone-prone areas.
• Water Tightness: Prevents rainwater ingress up to 750 Pa.
• Air Sealing: Keeps dust and pollutants out up to 600 Pa.

This means your windows will remain stable, airtight, and weather-resistant for years to come.

8. Aluminium Windows Are Easy to Maintain

Maintenance is often where aluminium truly outshines other materials. The smooth, powder-coated surface of Eternia’s frames requires only occasional wiping to maintain its lustre. There’s no need for repainting or polishing, and the material is naturally resistant to corrosion, making it ideal for coastal cities or humid regions.

9. They Can Be Customised for Any Room

Eternia’s wide range of aluminium for windows options ensures that every room in your home has the right design and performance.

• Living rooms: Opt for expansive, slim aluminium windows for natural light and views.
• Bedrooms: Opt for tilt-and-turn or casement models for optimal privacy and ventilation.
• Kitchens: Compact sliding windows make efficient use of space.
• Balconies: Pair windows with sliding doors for seamless indoor-outdoor transitions.

Every Eternia window can be configured with different glass options, from frosted for privacy to laminated for noise reduction, to suit your lifestyle.

10. Aluminium Windows Offer Great Value Over Time

While the initial cost of aluminium windows may vary based on size, design, and glass choice, they provide superior value over time. Their long lifespan, minimal maintenance, and weather resistance significantly reduce replacement and repair costs. Eternia enhances this long-term assurance with a 12-year warranty on frames and a 5-year hardware warranty, making them a smart and lasting investment for any homeowner.

Why Do Eternia Aluminium Windows Stand Out?

Eternia redefines window performance by combining craftsmanship, engineering, and sustainability. Here’s what makes them the benchmark in modern Indian homes:

• Crafted from Duranium: A proprietary alloy developed by Hindalco, 40% stronger than regular aluminium.
• WiWA-certified: Tested for protection against wind, water, and air infiltration.
• Design versatility: Available in sliding, casement, and fixed configurations.
• High-quality finishes: A palette ranging from subtle metallics to rich wood tones.
• Sustainable production: Fully recyclable, supporting eco-friendly living.

These attributes make Eternia’s luxury aluminium windows the perfect combination of elegance, safety, and performance.
