The science behind WiWA©

What does WiWA© stand for?

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.

How does this influence the window I buy?

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.

What are the advantages of WiWA© ?

  • A WiWA© score allows you to gauge the performance of windows on three parameters:
    wind pressure, water tightness and air permeability.
  • Helps you select a window.
    For example, if you want a window that can handle cyclones, check the wind parameter.
  • A scientific performance guarantee,
    since our windows are tested and certified against global standards.
