Why is there a limit for the slope of roofs and Pilkington Activ™?
Pilkington Activ™ needs both daylight and rain to work effectively. When the roof angle gets too low the rain does not wash the loosened dirt off as effectively. A good flow of water across the glass is beneficial. Pilkington Activ™ still gives better results than ordinary glass with low angle roof applications.

We recommend a minimum angle of 10 degrees, but 30 degrees or more is ideal.
