This passive-active venting system, along with decent bathroom and kitchen fans vented through the roof, should keep heat and moisture levels in the walls and plenum to a minimum.
|This solar fan will be mounted on the roof, at the front. It has a thermal switch attached, which will activate the fan at around 75 degrees F. Notice that it is not "Made in the U.S.A." but rather, "Made in Texas."|
|This is one of the two passive vents we are installing--in the holes left behind by the roofer back in 10/2009. They are in good spots on the roof already, thus no sense in fixing them just to put two more holes in the roof...|
