Self-cleaning glass has a thin photocatalytic coating on its surface. This coating uses the power of the sun’s ultraviolet rays to steadily break down organic dirt using the photocatalytic effect and thus loosen grime from the glass.
Self–cleaning glass also has hydrophilic properties. This means that when rain flows down a pane of glass it can wash away the grime loosened by the photocatalytic process. Together, these processes allow the conservatory glass to stay cleaner for a longer period than untreated glass.
Self-cleaning is a slow process that is fine for clearing small particles of dirt, but slow to remove a splatter caused by birds. In these circumstances you may need to wash the glass; if you do you should take the utmost care and follow the manufacturers or installers instructions. Try to use soft water and whatever you do, don’t scrub the conservatory roof or use any abrasive cleaning products as these can damage the self cleaning properties permanently.
You should also note that once you have cleaned the conservatory roof, it may take several days for the self cleaning properties to begin working automatically once more.
Self–cleaning glass can be used in combination with Heat Reflective Glass if you specify it to your conservatory supplier at the design stage.
