As the name suggests, ‘self-cleaning’ glass is a type of glass that is able to clean itself. The impossible dream has become a reality through many years of research and development. Pilkington launched the ‘Pilkington Activ’ window, which is the world’s very first self-cleaning glass.

Pilkington Activ uses a brand-new technology that enables the windows to self-clean and it does so by using an innovative dual-action function. This function uses the force of nature to break down the dirt using sunlight and then the dirt gets washed away by the rain. In addition to this, Pilkington Activ has a wide range of products which are compatible with other products. They have developed their products with innovative glass technology that allows their products to be combined with other features.


How Does It Work?

Pilkington Activ uses a microscopic coating with the unique dual-action function and is the world’s first self-cleaning glass. However, how does the glass self-clean?

There is a 3-step cleaning process to this. The first step of the process is to just wait for 5 to 7 days after installation to allow the special coating to activate completely.

The second stage involves breaking down the organic dirt with the special coating. The coating also reduces the amount of inorganic dirt that sticks to the window.

The last step is when water droplets are formed on the surface of the window. These water droplets will scatter to form a sheet which will carry the dirt particles off the window. The surface of the window will be cleaned off by water and it also washes the glass.
