| The hot box above is a representation
of an attic with Aluma-Foil installed. The hot box shows the
temperature difference between a homes attic with and without
radiant barrier, using infra-red heat lamps.
Left Side:
The left side shows a laid down radiant barrier with
unfaced R-19 fiberglass insulation. The thermometer reads
93.2 degrees F.
Right Side:
The right side shows unfaced R-19 fiberglass insulation
only. Its thermometer reads 152.5 degrees F.
There is a difference of 59.3 degrees F
between the two sides. This difference is due to the
Aluma-Foil's ability to reflect radiant heat away from the
insulation.
The numbers above were arrived at after a
six hour period with an ambient air temperature average of 84
degrees.
NOTE: Both sides reached their steady
state after only one half hour.
