Self Cleaning Glass
Self Cleaning Glass
Some manufacturers produce glass with a thin ‘photocatalytic’ coating on one side. This coating uses the ultraviolet rays from the sun to steadily break down any organic dirt on the surface.
It also has ‘hydrophilic’ properties which mean that when rain runs down the surface of the glass, it will wash away the loosened dirt.
Small particles of dirt will loosen and (providing there is rain) be washed off. This coating needs a minimum pitch of 10 degrees from the horizonatal to work effectively.
