Ive heard rumors of self-cleaning windows-is there any hope that it could be true?
Yes, it is true. It’s just becoming available in the US and it’s called Activ glass or SunGlass depending on the manufacturer. Its self-cleaning properties work like this: During dry clear weather, the glass uses the sun’s UV rays to break down the dirt. During wet weather, or when sprayed with a hose, the glasses composition reduces surface tension so water sheets down the window surface instead of beading like normal glass. This sheeting effect prevents streaks and washes dirt away. The costs will probable be 20-30% higher than regular windows. Stay tuned…
