Numerous homes in Canada already have had windows with Pilkington Activ(TM) Self-Cleaning Glass installed.
Pilkington Activ(TM) Self-Cleaning Glass works first by using energy from the sun to actively attack dirt, to break down, loosen and destroy it. This is called the photoactive effect. After being installed, windows with Pilkington Activ(TM) Self-Cleaning Glass need to be exposed to daylight for several days to activate the photoactive properties. Once activated, the photoactive process will continue to work at night and even on cloudy days.
And when it rains, water sheets off the active surface, washing away dirt, so windows dry clean without spots and streaks. This is called the hydrophilic
effect.
Pilkington Activ(TM) Self-Cleaning Glass can be used in new and replacement windows and skylights in homes, apartments and condominiums. It can also be used in commercial and institutional buildings, such as offices, schools and universities, retail stores, etc.
