Choosing the right material for windows and doors is crucial when building or renovating a home. In India, aluminium for windows and doors has been a preferred choice for years, thanks to its lightweight nature, corrosion resistance, and sleek aesthetics.
However, a new proprietary alloy, Duranium, has emerged, invented by Hindalco, the world’s largest aluminium manufacturer, offering improved performance and a modern appeal. But what exactly is the difference between Duranium windows and traditional aluminium options?
Let’s explore.
What’s the Difference between Duranium and Regular Aluminium?
Aluminium is a widely used material in residential and commercial buildings. Its popularity stems from the following benefits:
- Lightweight and easy to fabricate
- Resistant to rust and weathering
- Available in various finishes and profiles
- Cost-effective compared to other metals
For decades, aluminium window grill design and frame systems have relied on standard aluminium extrusions. It’s also extensively used in sliding and casement styles for both aluminium door and window sets.
Yet, while regular aluminium performs well in most situations, it does have certain limitations.
These include:
- Lower structural strength compared to new-age alloys
- Poor insulation against heat and sound
- Limited ability to support very large glass panels without reinforcement
What Are Duranium Windows?
Duranium windows are made using a high-performance alloy, specifically Duranium, which Hindalco invented for Eternia windows and doors to be eternally recyclable. It offers 40% higher strength than traditional aluminium and is designed to withstand the toughest conditions, including cyclonic winds. It enhances the core properties of aluminium. Developed with superior tensile strength and greater resistance to external stress, Duranium combines engineering precision with modern aesthetics, making it an excellent option for most homes.
Key benefits of Duranium include:
- Stronger structural integrity for slim yet sturdy frames
- Higher resistance to bending, warping, or deformation
- Improved thermal and acoustic insulation when paired with modern glazing
- Sleek, minimalist look suitable for designer homes
With these qualities, Duranium is becoming the go-to material for premium homes where form and function are equally important.
Aluminium Window Grill Design
Homeowners looking to adorn their windows with grills should know that while there is no difference between windows made from duranium and standard aluminium in this regard, most aluminium/duranium windows are outfitted in somewhat modern and minimalist settings, thus not being conducive to more intricate patterns. However, if it suits your home’s vibe, any aluminium window grill design can be adopted, offering visually appealing and secure grill options.
Aluminium Door and Window Performance Compared
Aluminium door and window systems made from standard aluminium are typically heavier and may require additional reinforcement for large sizes. They also tend to transmit more heat and noise, which can be a concern in urban Indian environments.
Duranium variants, however, allow larger spans and ultra-slim profiles while enhancing performance. These are especially beneficial for modern homes that incorporate:
- Floor-to-ceiling glass panels
- Sliding or foldable partitions
- Balconies with panoramic doors
In both fixed and operable systems, Duranium windows offer superior sealing, stability, and design clarity.
Cost Implications
Regular aluminium for windows is generally more affordable upfront. It’s a practical choice for mid-range housing, rental properties, or renovations with tight budgets. Duranium, while more expensive, is considered an investment in durability and design. It offers a longer lifespan, lower maintenance, and better resistance to weather and wear, especially in coastal or high-rise locations.
Which One Should You Choose?
Here’s a quick guide based on your needs:
- Choose regular aluminium if you’re working on a modest budget and need functional, dependable installations.
- Choose Duranium if you’re building a modern home, want minimalistic elegance, and need strong, long-lasting performance with reduced upkeep.
If your home design includes bold aluminium window grill designs, wide openings, or panoramic views, Duranium’s flexibility and resilience will stand out.
Final Thoughts
The choice between regular aluminium and Duranium windows ultimately depends on your priorities, budget, aesthetics, durability, and thermal comfort. While standard aluminium remains a good material for general use, Duranium windows push the boundaries of modern architecture with their advanced performance and sophisticated style.
For forward-thinking homeowners, architects, and developers in India, embracing a high-grade aluminium alloy like Duranium could mean fewer compromises and more comfort, security, and value in the long run.
