Duranium® is a world-first aluminium alloy developed by engineers at Hindalco, Eternia’s parent company. A flagship company of the Aditya Birla Group, Hindalco is the world’s largest aluminium manufacturer.
Duranium© is an ultra-tough and resistant alloy, and also provides a sleek, stunning finish to your window. As a result, your windows will be ultra-strong yet light and sleek, and also extremely easy to maintain. This helps windows withstand even the cyclonic winds. It also allows you to have large size windows, letting in maximum light and the best view with minimum obstruction.
Aluminium is also an eternally recyclable metal, which makes our Duranium®-made windows ultra sustainable.
WiWA stands for wind, water and air.
WiWA certifications verify that windows have been tested in an independent lab to meet international parameters for air permeability (a measure of how well sealing keeps out elements like heat, dust and noise), water pressure (how well your windows can keep out heavy rains) and wind pressure (how well windows can withstand heavy wind loads, including cyclones).
A WiWA© score can help you understand whether the window is a good fit for the weather conditions around your home. For example:
WiWA ensures that Eternia’s windows meet strict international standards, providing homeowners with confidence in the durability, weather resistance, and overall performance of their windows.
Yes, Eternia’s windows tested for WiWA© parameters are designed to perform well in various climates, offering resilience against strong winds, heavy rainfall, and contributing to a comfortable living space in terms of temperature and noise levels.
