Self Cleaning Glass

Self-cleaning glass has a transparent coating which keep the glass free of dirt. When it rains, the decomposed dirt naturally just rinses away. If there is no rain, rinse with clean water is sufficient to activate the self cleaning mechanism.

One of the well known self-cleaning glass is Pilkington Activ. It uses coating with a dual action of cleaning process, which are photocatalytic and hydrophilic. In photocatalytic stage the coating reacts with daylight to break down organic dirt. In hydrophilic stage, water hits the glass and spreads evenly, running off in a sheet and carrying the dirt with it.

For the installation, self-cleaning glass must be installed in an upright or sloping position to allow water to naturally run down the surface and wash away dirt. Silicon joints or silicon objects should not be used as they will damage the efficiency of the coating.

Sharp and abrasive objects should not be used to remove stubborn dirt on easy clean windows as they can damage the coating.
