Pilkington Activ™ is made up of 20–30 nm coating of nanocrystalline anatase titanium dioxide placed by an atmospheric tension chemical substance vapor depositing method on to soda-lime silicate float glass [ 10 ] . The outcome is an item with very advantageous noticeable transmission and reflectance qualities; Activ™ includes a noticeable reflectance of around 7% along with a noticeable haze of under 1%, but soaks up 20% of incident solar Ultra violet light which is often used within the self-cleaning procedure. The covering can also be strong and can’t be broken by use of Scotch tape or reasonable mechanical scratching; Pilkington are convinced that the covering can last the duration of your window frame..

It is quite a costly item but well worth it if you can push your budget
