Window Films and Sun Protection
During the design process,
architects typically locate windows to capture views of the surrounding
environment. Unfortunately, the sun can quickly ruin the enjoyment of
these grand vistas. Glare and heat can stifle our enjoyment of the view,
and the sun's harmful UV rays may fade and destroy not only fabrics,
but wood surfaces and works of art as well. The combined effects of
the sun can also contribute to the formation of skin cancers and other
skin diseases.
Protecting yourself against
these potentially harmful rays of the sun is the primary reason behind
the installation of protective window films.
In order to provide the very
best protection, Energy Control Consultants installs the very finest
product line available - 3M Architectural Window Films. These
films can block more than 99% of the sun's harmful ultraviolet rays,
reduce up to 78% of the sun's heat, they can reduce heat loss in the
winter by as much as 35% and provide significant protection against
glass breakage and other threats.
The number one request from
our residential clients is for fading protection. Let's take a closer
look at what actually causes this damage
Ultraviolet
radiation and fading damage
What is "UV" and why should I be concerned about it?
UV is short for ultraviolet,
a wavelength of radiation that is a part of the sun's spectrum. UV radiation
is invisible, yet it has a profound effect on us and on our homes. Overexposure
to UV in humans can cause sunburn, skin cancer, cataracts and can even
suppress the immune system with longer term overexposures. Just as we
can use protective clothing and sunblock to defend ourselves against
UV when we are exposed to sunlight, 3M Architectural Window Films can
prevent transmission of UV into your home.
So what is the "Big
Deal" surrounding UV, you ask?
Of all of the causes of fading,
ultraviolet radiation is the single largest factor in the fading of
soft goods
fabrics, carpets and other furnishings, contributing
up to 40% of the total damage. The good news is that our 3M film can
reduce the penetration of harmful UV to below 1%. Once treated with
film, UV ceases to be a contributing factor to your fading problem.
According to
the American Academy of Dermatology, exposure to the sun and its harmful
UV radiation has caused an epidemic rise in skin cancer cases in recent
years. Because of 3M's vast research into UV and how it damages human
tissue, 3m has recently released Aldara TM, a drug for treatment of
Actinic Keratosis, a certain type of skin cancer.
Because the reduction in skin damaging UV after the installation of
3M film is almost total, 3M Architectural Window Films have been awarded
a certificate of recommendation from the Skin Cancer Foundation of American.

As you can see,
the addition of 3M Architectural Window Films to your windows is the
best protection you can provide against the damage that UV causes.
Infrared
radiation and fading damage
Infra-red (IR) is another
range of radiation from the sun that is more commonly known to most
people as "heat". IR contributes as much as 25% of the total
damage from sun fading. Part of the IR actually exists in the visible
part of the spectrum, so it is necessary to use a protective film that
is at least lightly tinted in order to provide adequate protection from
damage. It is this IR reduction that provides our clients with the additional
benefit of reduced utility bills that, in some cases, repay the investment
in the film within a few short years.
Visible Light and fading damage
The intensity of the visible
portion of the spectrum is another major contributing factor to fading
damage. In "English", this means that the bright sunlight
that makes you reflexively squint (to protect your eyes) also causes
damage to your interior. Again, it is necessary to use a protective
film that is at least lightly tinted in order to provide adequate protection
from damage. If someone ever claims to have a "clear" protective
film, be very afraid
that person is selling snake oil. "Clear"
and "protective" are mutually exclusive
you cannot have
both and have an effective product.
Additional
causes of fading damage
Other factors that can contribute
to the damage that you may see in your home are the quality of colorfastness
of the dyes used in the fabric, the humidity (both high and low), the
amount of abrasive wear that the item receives, solvents or pollutants
in the air and the overall quality of the item in question. 3M Architectural
Window Films do not have any effect on these issues, and so therefore
we mention these to show that it is virtually impossible to entirely
stop fading damage from occurring.
Other protective
properties
The combined
factors in our films can also protect your expensive artwork. Since
UV, visible light and heat can all do damage to art, the addition of
window film can help prevent the harmful effects of these elements.
Another benefit of protective window film is that it helps to hold glass
together if it breaks. When glass with an application of window film
is broken it is held together as a single unit instead of shattering
into dangerous fragments protecting you and your family from injury.
Statistics show that flying, broken glass can cause more than half the
injuries caused during earthquakes.
Earthquakes,
you ask?
Oh, by the way
did
you know that eastern Tennessee is one of the most seismically active
areas in the country outside of California? LINK
