My house is a cape cod style, which presents a challenge. In the upper attic there is plenty of loose insulation, but it is right up against the roofing at the edges. I know I need to pull this back and put those foam air channels in. BUT, what about the area between my attic floor and the bottom edge of the roof (10-12 feet, probably)? I am not sure yet whether there is any chance for air to travel this path. I have no access to this area other than by tearing out walls or the roof. Gah!
I am looking at installing a powered gable vent. I have a continuous ridge vent now. If I can establish air flow from the soffits to the attic, it would seem that I should block the ridge vent so that the powered gable vent pulls air up under the roof? Also - the powered gable vents I saw at Menards/Lowes/Home Depot are thermostat controlled. They go off at the set temperature. These thermometers only go down to 50 or 60 degrees F. That seems too warm to me - in the winter it would seem that I would want the fan to go off at a much lower temp. Am I missing something here?
Thanks for any advice!
