Therma Vent is America’s Leading Energy Efficient Ventilation Technology. This is the only complete patented under roof ventilation system that stops all 3 ways heat is transferred by Releasing, Reflecting and Stopping the heat. It is affordable to the average home owner, and has a real return on investment.
Tests have shown that the Therma ventilation system has dropped attic air temperatures from 150 degrees down to 96 degrees at the base of the attic which was the same as the outside air temperature. A 54 degree temperature change has not been seen in any affordable ventilation system.
