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.
