The WiWA© effect: a safer, quieter and cleaner home.
Are your windows tested and certified for better protection?
The science behind WiWA©
WiWA© stands for wind, water and air. This is because Eternia’s windows are tested for three important parameters. Each parameter is rated from 1 to 10, with 10 being the highest.
1. Wind pressure: how well your windows can handle heavy winds, up to a cyclonic range
2. Water pressure: how well your windows can keep out water, even the heaviest of rains
3. Air permeability: how well your windows keep out loud noises, pollution and heat: creating a quieter, cleaner and cooler home.
Our windows are tested to meet the strictest international standards.
The wind, water and air scores will help you make a decision about what windows are perfect for your home.
For example, if you live in a city with extremely heavy monsoons, look for a high water score. Similarly, if you live in a very noisy or polluted area, look for a higher air score.
We have designed a special algorithm which will understand your home and the problems you face with your current windows, and recommend a window with the perfect WiWA© score for you.

Frequently asked questions
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).

Our windows are tested to meet the strictest international standards.
A WiWA© score can help you understand whether the window is a good fit for the weather conditions around your home. For example:
- Windows with a high air permeability score can keep out heat, dust and noise more effectively.
- Windows with a high water pressure score can withstand very heavy rains.
- Windows with a high wind pressure score can withstand very heavy winds, making them cyclone-proof.
Yes, all Eternia and Erigo windows are WiWA©-certified. Eternia range windows are also made with a world-first Duranium® alloy for extra toughness and improved finish.
