Solar Transmission Properties
Various types of PALSUN can be used to help reduce energy costs throughout the year. Textured, tinted, opal, diused,
and new PALSUN SolarSmart™ sheets feature properties that aect energy eciency beyond what is depicted on the next
page. Each of these products transmit dierent amounts of direct light in varying levels of light diusion, which may help
to spread the light throughout the structure or enclosure. The sheets also vary in their selectivity index (SI) values, which
determines how eciently they keep heat out while letting more “cool-light" in (See next page for more information on
SolarSmart™ products). PALSUN textured, diused and opal sheets are also suitable for incorporation into light xtures. They
enable designers to deliver the exact quantity and quality of light desired.

Terminology Used in the Table
Solar Radiation
The solar spectrum ranging from 300 nm to 2400 nm.
Included are UV, visible and Near-IR radiation.
Visible Light Radiation
The portion of the light spectrum whose wavelength ranges
from 400nm to 780nm.
% Light Transmission (ASTM D-1003)
Percentage of incident visible light that passes through an
object.
% Solar Heat Gain (SHGC)
The percent of incident solar radiation transmitted by an
object which includes the direct solar transmission plus the
part of the solar absorption reradiated inward.
% Total Solar Rejection (%SR
t
)
The percent of incident solar radiation rejected by an object,
which includes the solar reectance plus the part of the solar
absorption, reradiated outward.
%ST
t
+ %SR
t
= 100%
Shading Coecient (ASTM E424-71)
The ratio of the total solar radiation transmitted by a given
material to that transmitted by normal glass, whose light
transmission is 87%. It can be approximately calculated by:
%ST + (0.27 x %SA) = %ST
t
SC = (1.15 x ST
t
)/100
