Define the types of window film

The term window film comes while seemingly new, actually the early 1960s. While window film has many uses, then it is designed to control the climate within buildings because of sunlight. Early films reflects the Sun again way out of the window or the Interior of a building at the same time to see this still out. It was transparent. As this concept grew, the demand began to grow even after colour films. These colored films was soon integrated into an architectural building design. The film colours such as yellow, gold, bronze contain colorization, grey.

Then came the energy crisis in the 1970s. Window film and saving energy interest more people in the possibilities with this. It followed the study window film and its efficiency. Polyester was made early window film, which was 2 to 7 ml thick. Several thick layers of this film were often connected. A page was coated with a pressure-sensitive or water activated adhesive. The exposed surface has been treated with a harsh, scratchproof coating in turn.Chemical UV blocker called cyclic imino esters have been in the film eingebettet.Der sole purpose which was Film?s to offer only UV protection and resistance to glass break.

The problem with the early movie was that tend to absorb and the reradiate long wave infrared heat, rather than as transparent medium for handeln.Aber all of this changed, as the demand for slightly more efficient to grow. Today window films high-tech, so that you can meet a number of requirements.

So, what types of film on the market today is? According to popular mechanics include the most popular four:

1. Coloured FILM - is this film single-ply and colored with a standard scratch-resistant coating. While this sounds simple, be applied three separate technologies largely stored into the glass and drawn away from the external air movement to different performance characteristics for this film to min. heat rejected from the film. The other two processes called deposition technology (vacuum coating Metallization) and sputtering technology (Advanced Metallization), place a layer of metallic particles on the film, which gives it reflective coating.In any case, a second layer of films reject film the Beschichtung.Metallisierte protects heat by to reflect before it can be transferred through the glass.

2. Deposited FILM – the technology of this film has to do with the deposits put into it. For this film to be effective, the metallized coating must be pretty thick as the particles are relatively large.This film produced a darker, more highly mirrored surface.

3. GESPUTTERTEN FILM – is this a two fädiger window film metallized with metallized and UV layers practical benefits of sputtering are behandelt.Die that 25 to 30 different metals can be used, and the metallized coating is much easier.Different metals are selected to certain frequency bands radiation from the solar spectrum to subtrahieren.Das result is a highly reflective layer with very little mirror effect, heat absorption or color shift.Sputtering is more expensive, these films that control high end of the Preisspanne.Metallische slides show radiation due to reflection.Simplified film layers, consists of polyester metallic coating, glue and resistant coatings.

4. HYBRID FILM - this film is the combination of colours and Metalle.Ein example would be a combination of Grey dye and titanium coating - coupled, a film lead these two, the bright and not reflective.

Window film has come a long way, as newer technology replaced ageing wird.Jede entails change generally a more efficient and cost-saving product.
