Wall Vents for Bathroom Exhaust
Are there any exterior wall vents available that will seal well and not allow air to escape through stack effect? I hate the idea that I am building a tight house but will have 4 bathroom exhaust fans creating 4 holes in the envelope that could just draft out my air.
I don’t think I want the complexity of an actuated damper, just something other than thin sheet metal or plastic that will just flop around in the wind.
all suggestions are welcomed!
