Window film is a self-adhesive material that can be applied to new or existing glazing to solve a number of problems. Solar control, privacy, decorative and anti shatter films have been around for many years, specialist films such as anti graffiti and anti fog films are also being widely used in today's' market.
In its simplest form window film n&k is a thin sheet of polyester, adhesive and then a thin polyester backing liner. Additional sheets of polyester can be found on many films, two sheets of polyester is called two-ply, some safety and security films are also available in three ply. A metalized or dyed layer can sometimes be added between these sheets of polyester to add colour or tint and a scratch resistant coating can be found on the majority of films to protect from every day wear and tear.
Window film can be fitted to most type of glazing, they can all be fitted to flat glass but some films can also be fitted to raised or patterned glass depending on the flexibility of the film and the type of pattern, if the pattern is too raised the film n&k may not be successfully installed, however there is usually a flat side to all patterned glass. Another problem type of glazing can be compound curves found on the windscreens of cars. This is because the glass is curved in two directions, the film can be easily applied to glass curved in one direction but if it's a compound curve you will probably need to heat shrink the film, specialist car window tints are available for this, these are usually a thinner material and are specially made to be heat shrinkable more so than a standard window film.
There are three technologies that give different performance characteristics, these are; dyed, deposited and sputtered.
Dyed window film
Dyed films are usually on the cheaper end of the market but these films shouldn't be disregarded, as there are some very good dyed films on the market. The bottom end of the market is glue tinted, glue tinted films have the dye mixed with the adhesive (scratch resistant coating (not always present), polyester sheet(s), adhesive mixed with dye, backing liner). These are usually sold on the Asian and South American market but are still sold in Europe. These films are not usually particularly colour stable, as there's very little protection for the dye, as such they can fade very quickly. Because the dye is mixed with the adhesive the colour is not always uniform and the colour can be moved during installation.
A better type of dyed film is one that has the dye sandwiched inside two sheets of polyester, this film is much more colour stable as it is protected by the polyester sheets, this also provides no problems when installing as the adhesive is clear and there can be no colour shift. These films can very often be supplied with as much as ten years warranty.
