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. Click here.
Wind score of 8/10, as cyclones are uncommon
Water score of 8/10, since heavy rains occur sometimes
Air score of 10/10, since noise and pollution are a serious problem
