Selective Wavelength Films
Technology
has changed since
3M invented window films
in 1966. Back then, increased
sun control or heat gain
reduction performance resulted
primarily from depositing
heavier levels of metal on a
polyester film. However, this
increased performance sacrificed
the film's visible light
transmission.
Since then,
3M
has developed films that manage
the solar spectrum selectively.
What this means is that
selective wavelength films block
more of the near infrared or
heat portion of the spectrum and
less of the visible light.
Selective wavelength films
provide an improved balance
between performance and light.
The unique engineering,
construction, and use of
materials allow these special
films to let the natural visible
light shine without a compromise
in performance.
This is important to many of our
clients today as they strive to
use natural visible light (day
lighting) in their buildings.
With
3M's
selective wavelength films, our
clients can better maintain
energy-efficient natural light
and still help control
temperature imbalances within
the building.
