Are cupolas worth considering on a well insulated home for ventilation?
Are cupolas worth considering on a well insulated home for ventilation in the summer? In zone 5a there are some months where the day time requires some A/C and the night does not. A whole-house exchange of air would be nice around 8 o'clock at night, when the temps outside drop.
The idea would be to open up the cupola along with the first floor windows and allow the stack effect to exhaust the air. I guess it's the same idea as the whole house fan that pulls all the air out of the house and into the attic. We had one in our old house and it never seemed to work as good as the theory.
My concerns about a cupola are, another hole in the roof, demanding more detailed flashing at the peak, potential for leaks, another hole in the insulation, possible bug haven, actual usage of 4 1/2 months at best in a year, and most importantly..........do they actually work?
Thanks for any advice given
