History of Window Tinting
In
the beginning, a first generation design window film product was dyed
only. The dyed films are considered basic products which work on the
principle of absorbtion. The darker the film, the better it works, but
now we have a lot of people tired of difficulty with night
visibility... These basic dyed films are still in wide spread use today
due to their low cost and great appearance, but are not very durable to an extreme climate, but on the whole perfectly satisfactory for UK use.
As
the nineties came with computers, a second generation design product
included metalization of some sort, integrated with the dye. This
produced a "hybrid" film containing dye to absorb heat and also metal
to reject the sun's rays, and therefore heat. This hybrid design window
film often provides 25% greater heat reduction shade for shade...
across the board. They are considered by many consumers as the best
they can do. This dyed / metal "hybrid" design window film is a great
addition for many reasons, and yieids high value for any application.
Today,
a third generation design window film product has been made possible
only through the recent development of nano-technologies. These new
films are manufactured with traces of dye and metal, but consist mostly
of ceramic or crystalline oxides which are used to block
specifically... the infrared part of the solar spectrum.
From
our sun, we receive light rays, heat rays, and ultraviolet rays, and
thats it. All other forms of radiation are either filtered by our
atmosphere or man made. Of all the rays we are exposed to by our sun,
the ultraviolet rays ( UV = 3% of the suns total radiation ) are not
good for human beings, and is the part responsible for unwanted health
conditions. The infrared rays ( IR = 56% of total solar radiation ) is
the heat factor. This is the part that irritates existing health
conditions with heat build-up in a car. The visible light rays ( VLT ~=
41% of total solar radiation ) and is the part we use to see. Notice
the three parts equal 100% of the total solar energy ( rays ) coming
from our sun. The parts overlap somewhat, and the specifications would
vary accordingly, but you get the idea. So now we have a nano tech
design window film who's build is directed precisely at the part of the
solar spectrum which we wish to manipulate, the infrared heat rays.
The
key here is: a custom design "IR blocker" automotive window film, that
provides all the benefits of conventional window films while reducing
heat much better, yet are virtually colorless for excellent night
visibility. The design, build, and marketing focus for these lightly
shaded films is towards windshields... because the future of cars
includes further aerodynamic refinement, and the windshield is usually
the largest and most slanted glass area for the suns rays to come into
a vehicle.
When
we drive, we view the world we are approaching through the front
windscreen, so visibility and a clear un-obstructed view is absolutely
necessary. Options available to the general public in the past were
limited at best. Usually some dye or metal was necessary to provide
heat reduction.
