Vent fan Damper noise
Posted by Casman on December 09, 2002 at 11:26:48:
Just installed a panasonic vent fan in my upstairs full bath. It's super quiet exceptwhen the wind blows. The metal damper plate makes a clunk noise whenever its kinda windy. Any solutions? The transition from the attic to the outside also has a damper flap, Should I somehow extend the outer plastic Cover downward to more or less block the wind?
