Easy Clean Glass
There are several types of easy clean glass currently available. When glass viewed under a microscope, you can see that the surface has an uneven surface (microscopic peaks and valleys). There are two available types. Pilkington makes their activ glass smoother (this removes most of the mountains and valleys). Several other glass companies smooth their glass in a secondary process by applying a solution to the surface of the glass (much the same way as applying polish to your car). Both methods do the job and make it easier to keep the glass cleaner. This product is ideal for bifold doors.
Does it clean itself
There is no such thing. It needs the ultraviolet light from the sun to harden the surface dirt and rainwater to wash the flaky dirt away. So if your glass is shaded and does not get much direct light or shaded from the rain the glass will not clean itself.
Effective
Is it effective absolutely if exposed to direct sunlight and rain? Sheltered locations are not suitable. The glazing requires UV rays from daylight and rain to wash off the loose dirt. In the right location, easy clean glass is very effective.
Pilkington Activ
Pilkington Activ glass is manufactured smoother at source in one process. The surface will last the life of the glass.
SGG BIO-CLEAN
SGG BIO-CLEAN has a secondary coating applied to the glass to do the easy glass cleaning with daylight and rain. The applied secondary coat can wear off.

Nobody likes cleaning, and it often falls to the window cleaner. When the glass has been cleaned the home looks great, this is why we have a natural clean glass.
Roof Glazing
Self cleaning is most commonly used on a roof or those difficult to access windows. The activate the product is does need daylight and rain so don’t use in shaded areas.
