The sum total of the solar spectrum. Solar Energy
Reflectance - In the solar spectrum, the percentage of
solar energy that is reflected from the glass surface(s).
The percentage of ultraviolet,
visible and near infrared energy within the solar spectrum
(300 to 2100 nanometers) that is transmitted through the
glass. Solar Heat Gain Coefficient (SHGC) - The portion
of directly transmitted and absorbed solar energy that
enters into the building's interior. The higher the SHGC,
the higher the heat gain.

from the glass surface(s)

Tinted and/or coated flat glass that reduces
the amount of solar heat gain transmitted through a glazed
product. STC (Sound Transmission Class) - A single number
rating derived from individual transmission losses at
specified test frequencies (for more information see ASTM
E 90 and ASTM E 413). It is used for interior walls, ceilings
and floors and in the past was also used for preliminary
comparison of the performance of various glazing materials.
STL (Sound Transmission
The reduction of the amount of sound energy
passing through a wall, floor, roof, etc. It is related
to the specific frequency (Hz) at which it is measured
and it is expressed in decibels (dB). Also called "Transmission
Loss (TL)." STC Rating - Abbreviation for Sound Transmission
Class Rating. When glass is used on the building interior,
the sound transmission classification (STC) value can
be used to categorize the glass performance. The STC rating
is a single-number rating system for interior building
partitions and viewing windows. The STC rating is derived
by testing in accordance with ASTM E90, 'Laboratory Measurement
of Airborne sound Transmission of Building Partitions".
The STC value is achieved by applying the Transmission
loss (TL) values to the STC reference contour of ASTM
E413, "Determination of Sound Transmission Class".
The STC rating is a basis for glass selection. Its original
intent was to quantify interiro building partitions, not
exterior wall components. As a result, it is not recommended
for glass selection of exterior wall applications, since
the single-number rating was achieved under a specific
set of laboratory conditions. Stones - Any crystalline
inclusion imbedded in the glass.
