Going to replace my 25 year old Gable vents this weekend. Going to go with the Masterflow 1600cfm PG3 here: http://www.homedepot.com/p/Master-Fl...6#BVRRWidgetID
Same size dimensions as the old Broan ones there now. I still have the paperwork from the Broan ones from 25 years ago if you can believe it.
Anyone make a good recommendation to minimize vibration down the walls? Maybe I need to make a change to the way I mount it or put something in between the brackets and the plywood there now? Rubber, plastic or a 3/4" piece of strapping? Or maybe the ones there now are just so old that a bearing is out of whack causing the vibration??
