HRV port installation
Can anyone point me to a detail for passing HRV ports through a thickly insulated envelope?
I haven’t decided yet whether I will pass the ports through the rim board assembly or the wall above – I’m leaning towards the wall above so as to lift the ports well above the winter snow line.
The manufacturer’s installation detail calls for simply passing through a 6″ galvanized round duct… but I’m not sure I like this approach.
Another approach I have been considering is to use, say, 6.5″ or 7″ PVC as a conduit for the 6″ galvanized duct, then filling the gap between with one-part foam…
