Frequently Asked Questions

Eternia offers aluminium windows and doors of every type, size and colour! Our main offerings include:

  1. Sliding aluminium windows and doors.
  2. Openable/casement aluminium windows and doors.

We also offer aluminium windows and doors for all rooms: including living rooms, kitchens and bedrooms.

Our aluminium windows and doors can be classified into Duraslim Edge, Duraslim and Essentials - which are three ranges of high-quality products designed to ensure that every Indian home can have aluminium windows.

Every home’s requirements are a little bit different. Here are a few things to keep in mind when you’re buying windows in India:

Resistance to extreme weather

India has both extreme heat and heavy rains. It is also at number 4 in the world in terms of number of cyclones per year. Your windows should be able to withstand all these. Many wooden, uPVC and conventional aluminium windows available in the market today are not tested and certified for protection against wind, water and air. You should always check for such certification before you decide which windows to buy.

However, Eternia aluminium windows and doors are WiWA©-certified, which means they offer excellent protection against cyclones, water leakages, noise, dust and heat. You can also try Eternia’s Know Your WiWA© score feature to find that perfect window.

Ease of maintenance

Your windows should last you decades. Wooden and other ordinary windows are prone to problems like termites, mold, warping and degradation and hence require extensive maintenance.

Eternia Aluminium windows are made of Duranium®, a one-of-a-kind aluminium alloy designed by Hindalco’s engineers. It makes for extra strong windows which have a sleek finish and last for decades.

Eternia also offers an industry-first 12-years warranty on profiles and a 5-years warranty on moving parts. It also offers India's first annual maintenance service for windows that includes cleaning and maintenance by trained professionals.

Aesthetics

Eternia aluminium doors & windows not only match the look of wooden and uPVC windows, but also offer sleek frames with a curved aerodynamic interlock to take the beauty of your home a notch higher. The world's only windows made with Duranium®, Eternia doors & windows offer superior finish. In aluminium doors & windows, you also have the option to choose from hundreds of colours and finishes to match the decor of your home.

Safety

When you’re buying doors and windows, safety should be of a high priority. Eternia Aluminium doors & windows come with safety features like anti-lift plugs and multipoint locks that add an extra layer of protection for your home.

Compared to wooden and uPVC windows, Eternia aluminium doors & windows excel in other safety parameters like fire safety. That's because aluminium does not catch fire easily and also has a higher melting point.

Eternia aluminium doors and windows are made of material mined and refined by Hindalco, a flagship company of the Aditya Birla Group, ensuring authenticity and transparency. Be sure to check the authenticity of the material used in your window to ensure good health and safety.

Ease of Use

Doors and windows of your house are something you engage with every day and the ease of use is very important. Eternia windows and doors are made of custom-designed hardware and accessories that ensure smooth operations for years. For example, its locks and rollers are built to last for over 15000 cycles.

Yes, we manufacture a wide range of aluminium windows and doors.

Our aluminium windows and doors are made with a world-first aluminium alloy called Duranium®, and are WiWA© certified, which means they can withstand heavy rains and cyclones, and keep out noise, dust and heat. Our aluminium windows and doors come in a wide range of colours and finishes.

Our aluminium windows and doors can be customised in a wide range of colours and finishes, including the wood finish. You can design your own window and view our range of colours and finishes here.
