"Have you noticed how warm your home is well into the cooler evening hours? Your attic insulation has stored heat all day and because heat migrates to cold, this unwanted heat moves into the cooler living area below and is trapped, making your evenings uncomfortable."
An Aluma-Foil Radiant Barrier is one of the most affordable and easy to install solutions for radiant heating.
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.
