UV-inhibiting window films based on ceramic materials are being used to prevent
solar energy from driving up cooling costs and damaging skin and surfaces.
The window film industry, particularly in the residential
market, has long been impeded by a seemingly insurmountable obstacle-how to
eliminate solar energy gain without introducing color or reflectivity into the
laminate. Homeowners who wish to stabilize interior temperatures and protect
their family and furnishings from harmful ultraviolet (UV) rays have always had
to compromise aesthetics for comfort and safety.
While some consumers have been willing to
make this trade, many have not. The reluctance of property owners to live with
dyed, tinted or reflective windows has slowed the adoption of a high-value
material that has been proven to reduce energy consumption and UV damage. Each
year, solar control film makers have introduced products that have been
slightly lighter in color or marginally less reflective, but these incremental
improvements have not been enough to thrust the industry forward.
A Ceramic Solution
After months of research and experimentation, Madico, Inc. has
developed a high-performance, UV-inhibiting, ceramic-based material that does
not compromise visual acuity for the homeowner.* The new material has very
little reflection compared to films manufactured using traditional metals.
The ceramic material-in this case, titanium nitride-is deposited on a polyester
base film using sputter deposition, which is a method of depositing thin
coatings by sputtering a block of source material onto a substrate. Sputtered
atoms ejected into the gas phase are not in their thermodynamic equilibrium
state and tend to deposit on all surfaces in the vacuum chamber. A substrate
placed in the sputtering chamber is therefore coated with a thin film of the
sputtered material. After the sputtering phase, the films can be laminated to
other polyester layers and scratch-resistant coatings are applied. The films
are then installed on glass by professional dealers using a mild soap solution.
As any manufacturer knows, consumers don’t care how a
product is made
, they only
want to know what it does
. And the new
films do exactly what consumers have long demanded-they prevent solar energy
from driving up cooling costs, and stop solar rays from damaging skin and
surfaces without dramatically affecting the appearance of the windows.
The new films reject up to 61% of the total
solar energy while still providing a clear view of the outside world. In fact,
homeowners have said that the difference between traditional window films and
the new films is like the difference between analog and high-definition
Of course, film clarity is just one the consumer demands. Homeowners also
require that their solar control films meet rigorous performance standards. To
this end, the new films block 99% of harmful UV rays, provide superior infrared
rejection, boast extremely low reflectivity and dramatically reduce glare.
Since introducing the new film line less
than a year ago, Madico has overtaken competitors in the premium solar control
window film sector. The company continues to unveil new members of the film
family, which now also includes ceramic-based materials designed for commercial
and automotive applications.
