Our house was built back in 1978 and they put in a big vent pipe with the rotating cap to vent the attic. 2 years ago we had our roof reshingled and we had them install proper roof ridge vents and got rid of that stupid pipe. Now the attic seems to breathes better.
I do have one question though, I just remodeled our master bath a few months ago and put in a nice quiet Panasonic vent which vents out of the side of the house, above the attic. The vent cover keeps freezing open whenever we use it and I have to close it manually. Is there something we can do to keep this from happening?
There are a lot of options for dampers on vents... I prefer the floating balls.
Insulating the pipe right to the vent will keep the vented air warmer and slow down the frosting at the vent.
If you have a louver style a counterweight (small machine screw should be close to right) can be run through a slat and adjusted to weigh just enough to close the damper when the fan goes off.
