b'Reduce window cleaning with ClearShield protectionNon-stick glazing throughout your homeDid you know theres a solution for all windows and doors that takes away the hassle of frequent cleaning and keeps them looking good as new for longer?You can benefit by opting for Ritecs award-winning ClearShield System which is available on all our sealed units. This has been specially developed for the protection, renovation and maintenance of both new and already installed glass.Just like a non-stick frying pan, ClearShield provides a protective barrier for the surface of glass that is much more effective than a coating. It cuts the amount of window cleaning you will need to do by up to 70% without affecting the transparency or solar gain (g-value) of the glass.How ClearShield worksYou wouldnt know it, but glass suffers from corrosion. Just as metal rusts, glass is subjected to a corrosion process caused by reactions between the glass surface and gases in the atmosphere.Even a single droplet of moisture on unprotected glass can produce sufficient damage, and this can be visible in good lighting. No glass surface is perfectly smoothit actually consists of microscopic peaks and potholes. Both organic and inorganic contaminants fill these potholes and chemically react with the glass, firmly bonding to the surface. Because of this, cleaning glass becomes more difficult over time and visibility deteriorates.ClearShield transformsClearShield is a polymeric resin and, when applied to ordinary glass, it cross-links to form a strong chemical bond. ClearShield is completelytransparent, chemically inert, non-hazardous and UV stable. Unlikea coating, ClearShield becomes part of the glass so will not peel,flake or crack.The result is a low maintenance sealed unit featuring glass thatprevents contaminants from bonding to the surface to limit thedamage caused by corrosion and chemical attack.Dirt can also still be removed with ease using normal cleaningmethods.
