Dyed Film Window
film that uses either a submersion process or a dyed adhesive process
to deposit dye onto its surface to achieve the qualities and look of
tinted film.

measure of surface's ability to absorb or reflect far-infrared
radiation. The lower the emissivity rating, the better the insulating
qualities of the installed window film.
Hybrid Film Window film that is made up of a combination of metallic film and dyed film to achieve the qualities and look of tinted film.
Infrared Light A
form of electromagnetic radiation with wavelengths between 0.
7 micrometers (0.0007 millimeters) and 1 millimeter. These wavelengths
are longer than those of visible light, but shorter than those of
microwaves. (The prefix 'infra' means 'below; infrared refers to
radiation below the frequency of red light.) Infrared light is
primarily thermal radiation, and we can think of this as being heat.

deposit metals onto its surface to achieve the qualities and look of
tinted film.
Shading Coefficient The
ratio of solar heat gain passing through window film to the solar heat
gain that occurs under the same conditions if the window were made of
clear, unshaded double strength window glass. The lower the number, the
better solar shading qualities of the installed window film.
Total Solar Absorptance The
percent of incident solar radiation that is absorbed by the installed
window film. The lower the number, the less solar radiation absorbed.
Total Solar Energy Rejected The
percent of total solar energy (heat) rejected by the installed window
film. The higher the number, the more total solar energy (heat)
rejected.
Total Solar Reflectance The
percent of incident solar radiation that is reflected by the installed
window film. The lower the number, the less solar radiation reflected.
Total Solar Transmittance The
percent of incident solar radiation that is transmitted through the
installed window film. The lower the number, the less solar radiation
transmitted.
U-Value The
ability of heat to transfer through one square foot of window film for
each degree fahrenheit difference in temperature. The local climate or
environment in which the window is located, affects the level of heat
transfer and the rate. In summer, heat transfers from the outdoor air
to indoor air. In winter, heat transfers from indoor air to outdoor
air. The lower the U-Value, the better insulating qualities of the
installed window film.

window film. The lower the number, the less ultraviolet transmitted.

radiation as colors ranging from red (longer wavelengths; ~ 700
nanometers) to violet (shorter wavelengths; ~400 nanometers).
Visible Light Absorptance The
percent of total visible light that is absorbed by the installed window
film. The lower the number the less visible light absorbed.
Visible Light Reflectance The
percent of total visible light that is reflected by the installed
window film. The lower the number the less visible light reflected.
Visible Light Transmittance (VLT) The
percent of total visible light that is transmitted through the
installed window film. The lower the number, the less visible light
transmitted. As an example, limousines usually tint their windows with
films that have a VLT of 5%.

This method is used for enhanced glass retention, anchoring 8 Mil or thicker
safety film to the window frame with a metal batten system. The safety film
is installed to the glass, overlapping the window frame by approximately 1
inch. A metal batten system is placed over the overlapped film and screwed
into the existing window frame, securely attaching the window film to the
frame. Depending on the type of glass retention needed, the mechanical
system can be attached as a one-sided (top), two-sided or four-sided
installation.

(saf’te · film) n.
Safety film is composed of incredibly strong, optical-quality clear or
metallized polyester, high-grade ultraviolet inhibitors, special laminating
and mounting adhesives, and scratch-resistant coating. The product is
retrofit to interior glass surfaces for glass breakage protection. When
events such as natural disasters, vandalism or bomb blasts cause glass to
break, the film’s flexible construction and pressure-sensitive mounting
adhesive help hold the shards on the film. This reduces the potential for
personal injury and property damage. Safety film is also referred to as
anti-shatter film, glass fragment retention film, blast mitigation film and
Mylar.
Bekaert’s safety film is available in thickness ranging from 4 Mil (.004”)
to 14 Mil (.014”) – with thicker films offering greater protection.
Armorcoat is
available in all thickness, offered as either a clear or metallized safety
film. Select
Panorama films are offered as a 4 Mil and 8 Mil upgrade.
