Key highlights


1. Duranium®: Eternia windows are made of Duranium, a special aluminium alloy developed by Hindalco’s engineers, who design parts strong enough for aerospace missions. Duranium has higher yield strength which ensures that the window does not shatter in extreme situations – means it has a better ability to withstand cyclones. It also makes the Eternia windows sleeker in design so you can have large windows with minimum obstructions. An additional advantage of Duranium is a better surface finish.

Duranium™ is difficult to imitate, giving you the certainty that the products you receive are authentic.


2. WiWA© Score: These windows have a special WiWA© score and have been tested and certified by an independent lab to meet global requirements. This means these windows are tested & certified to provide protection from cyclones, water leakage in the heaviest of rains, stop sound from coming in and AC air from going out reducing your electricity bills.

WiWA© also helps you determine the right window for your house, by answering 5 simple questions, using a patented algorithm.

Eternia premium sliding doors and windows have an overall WiWA© Score of 9.
