Johannesburg South Africa 24 February 2012
In a recent Window Film Indaba at the Nelson Mandela Square in
Sandton Johannesburg, Leon Levy the founder of Klingshield, the largest
distributors and installers of window film and tinting in the South
African market, discussed in detail the difference between new window
film technology and old window film technology. Levy was also the
inventor of see-through signage worldwide utilizing window film in
When I started out four decades ago, the window film business offered an
aesthetic benefit as it consisted of dyed films in two colours – brown and
grey, which were attached to windows to change the colour of the glass.
This process offered a slick tinted look to windows which designers
and decorators used to improve the visual look of their projects. Over
the years improvement and advances were made in the manufacture of
window film and reflective metalized films were being laminated to the
dyed films to offer a reflective look once applied to glass.
The market place started to utilize these window film products to reflect the
sunlight from passing through glass. Window films became known as
energy savers and were being installed in offices, homes and cars to
reduce temperatures inside spaces as well as reducing the glare.
Some consumers were also installing window film because it stopped up
to 99% of the ultraviolet which causes furnishings, fabrics and
upholstery to fade .
In recent years window film manufactures have come out with new
sophisticated technology in window film with the introduction of many
new products which offer far more advantages than old technology window
film said Levy at the Indaba.
With the introduction of ceramic sputtered film the consumer can now
have a window film applied to his windows which will stop most of the
sun’s heat in summer and also keeping in most of the generated
heat in the room in winter. The new generation window film is
very light, allowing in most of the natural light, unlike the old style
window films which created dark rooms to get the same effect as the
new generation ceramic sputtered films. This is a major breakthrough
Another new window film technology is now also available said Levy.
Switchable retro self adhesive window film has now entered the world
market. This window film consists of a liquid crystal polymer which changes the appearance of window film with the use of electrical currents from a
clear window to an opaque window at the touch of a button.
Transition films are on our drawing board which will adjust with the
amount of sunlight from clear to highly reflective once the
film is applied to windows. This will offer the best of both worlds –
similar to sunglasses that get darker when one is exposed to a sunny
outdoor situation and goes clear when one goes indoors said Levy.
The next move will be prescription window film designs for one’s
These are exciting times for us as leaders in window film technology and
Innovation, said Levy with lots of passion and excitement in his voice!
