Effects
Of Solar Radiation On Glass
Sunlight is a source of "cold" radiation
in the sense that it does not transmit
heat but rather pure energy. It is the
absorption of this energy by a solar
screen shade that transforms it into
heat.
An ordinary window lets 82% of solar
energy pass through. Absorbed by walls and
furniture, this energy is reflected in the
form of very long wavelengths unable to be
released through glass - this is known as
the "greenhouse effect." The trapped heat
can only escape when the outside
temperature is lower than that of the
room. In the case of insulated glass this
rate is even slower.
Efficiency Of Solar Shades
If one side of a home has at least 50%
of the glass unprotected and exposed to
the sun, and with the windows closed, the
temperature of the home can be 20 to 30
degrees higher than the outside
temperature. For example, if the outside
temperature is 82 degrees the inside
temperature could be as high as 105
degrees. Thanks to its energy efficient
properties, solar shade fabrics can
effectively block solar radiation before
it reaches the inside room letting as
little as 12% of solar energy through.
Under certain conditions this can be
reduced even further.
Comfort And Energy Savings
Numerous studies measuring energy
transmission and efficiency have been
conducted throughout Europe and North
America demonstrating that solar shades
can enable a 30 to 40 degree reduction in
the maximum temperature of the room
without the use of air conditioning.
Combined with air conditioning, solar
shades allow a reduction in cooling
equipment capacity of up to 30% and
reduced energy consumption up to 30% as
well. During the winter, solar shades lowered at
night create a cushion of insulating air
in between the fabric and glass offering
reduced heating costs as well.
Did You Know
It is estimated that Americans
represent 4% of the world's population and
use 40% of the world's energy. Solar
shades are smart - for you and our
planet.
