Self Cleaning Windows? Simply Too Great to Be Real!

What is self cleansing glass?
Self cleansing glass is glass which has been very finely coated with titanium dioxide, an inorganic pigment that is made use of in a variety of products consisting of sun block (reflects UV rays), toothpaste and as a whitener in white paint.
To place it simply, it utilizes a dual-action procedure in which natural dust is broken down by daylight as well as is then washed away by rain, hence making it much easier to keep clean.
More concerning just how it functions
Self cleansing glass functions by 2 procedures:

Photo-catalysis - the action of sunlight onto the surface area of the glass gnaws dirt. It does this by absorbing the UV element of sunlight which after that damages down any type of natural material on the surface area of the glass.
Hydrophilicity - as opposed to creating droplets that run down the window in rivulets leaving streaks, the rain spreads out as a continual sheet washing the glass clean.
Does it constantly work?
Jeff Howell, checking out the advantages, кликнете върху идващия интернет сайт and disadvantages of self cleaning glass in The Telegraph (June 27th 2005) concluded that self cleaning glass is "self-cleaning as long as it does not obtain filthy."
Whilst self cleansing glass certainly carried out well in research laboratory checks the exact same problems hardly ever apply in real life. If rain is eyelashing versus one side of the home, the various other will undoubtedly continue to be reasonably dry as well as therefore unwashed.
Jeff spoke with one maker of self cleaning glass that admitted that their product is only "self-cleaning" as long as it is consistently hosed down with water, as well as then it functions ideal when the water flows gradually down an incline - such as on a conservatory roofing system - as opposed to directly down, as on regular upright windows.
... no simple solution to your window cleaning troubles I'm afraid! Best stick to the experts.
