"KRINKLGLAS®" SAVES ENERGY DUE TO ITS LOW THERMAL CONDUCTIVITY and HEAT INSULATION
technical buffs .....
Not only is Krinklglas® cheaper than stain glass, its
also better ... here's why.
Thermal conductivity is defined as the time rate of transfer of heat by conduction, through the thickness, across unit area for unit difference of temperature, and has a "k" factor or value for each material.
The "k" factor is given
in two (2) units:
a) BTU (British thermal units) per hour per square foot for a thickness of one inch and a difference of temperature of I ° Fahrenheit, abbreviated BTU/(hr)(ft2X"F\inch)
b) Calories per second per square centimeter for a
thickness of one centimeter and a difference of temperature of 1° Centigrade or
Celsius, abbreviated cal\(scc)(cm2) <"C\cm)
In order to show the low values of
heat conductivity for KRINKLGLAS®, which makes it the perfect choice for ENERGY SAVING INSTALLATION, we quote the
following technical publication: from Modern Plastics Encyclopedia. 1962 Edition, page 41 and 42:
"The terminal conductivities of pure resins,
like their specific heats are grouped in a narrow
band, though the range of values/or all material are wide. At the low end of the scale among plastics are the styrene polymers with k*s of about 0.QQQ2 metric unit, while high-density polyethylene leads the family with O.QQ12 unit. These values place plastics AT THE BOTTOM OF THE THERMAL CONDUCTIVITY SPECTRUM AMONG SOLID MATERIALS. The only solids with smaller k values are those containing substantial fractions of "dead" air or other gases, such as cork, felt, balsa wood, mineral wool, and of course the foamed plastics.
THUS PLASTICS ARE EXCELLENT
For comparison, the k values for white
pine, concrete, WINDOW GLASS, marble, steel, aluminum,
and copper at room temperature are, in that order:
».»M3&. O.M22. C.M12 to O.M25. O.MMto
tt.W7tt. 0.104, 0.487, and ».»222 cal/sf.
The most recent value of thermal conductivity for
acrylic-polyester fiberglass reinforced panels run
from 1.7 to 8.7 x 10-4 cal/»q.cm/sec/(°C/cm)
as per data given in the Modern Plastics Encyclopedia, 1975-7fi Edition, page 618, for the Laminates Chart.
Comparing these ranges of values for acrylic-polyester
fiberglass reinforced panels with the range of
values for window glass, the results are obvious:
Acrylic-polyester fiberglass reinforced laminates
1.7 to 8.7 x 10"* units, Window glass 12.0 to 25.0 x W' units, and proves that
KRINKLGLAS® acrylic-polyester fiberglass
reinforced panels INSULATE FROM HEAT AT LEAST 3 TIMES MORE THAN GLASS AND AS MUCH AS 7
TIMES, WHICH MAKES AN AVERAGE OF
These facts can be corroborated by other independent
sources; to wit, The Handbook of Chemistry and Physics, S5th Edition,
page E5, gives the following value for the thermal
conductivity of glass as a building material: 5 to 6 BTU/ (hr)(sq. ft.) (°F/inch). The Handbook of Reinforced Plastics of the Society of the Plastics Industry, Inc. by Samuel S. Oleesky and J. Gilbert Mohr, 1964 Edition, page 459, gives the
following value for the thermal conductivity of glass-
polyester laminates: 0.97 BTU/(hr)(sq. ft.) (°F/inch).
Which leaves no doubt as to the INSULATING
VALUE OF KRINKLGLAS®, WHICH CAN BE CONSIDERED TO BE
5 TIMES BETTER THAN GLASS.
