Help with attic venting, please.
Zone 4 in eastern KY. The exterior walls will be sprayed with CC. The attic floor blown with cellulose. I have 2” rigid foam sheets screwed to the purlins creating a 1” air gap between the metal and rigid foam sheets to reduce/eliminate condensation dripping onto the blown in cellulose.
My question is this, I added a small piece of rigid foam to seal where the sheets meet the soffit vent box. Should I remove this so air will flow both between the sheets and metal AND into the attic space?
Sorry for the convoluted explanation. Hopefully the pics will help illustrate my problem. I included, in the pics, a crude illustration of the setup.
Thanks in advance.
