Bathroom fan after attic was sealed
We have open cell spray foam r44 on the roof deck in NY. Near NYC
i realized one of the bathrooms doesn’t have a fan and after showers the humidity can get trapped in the attic. Having an electrician put a 110 CFM fan in ducted outside. He wants to duct into a soffit and drill a hole. How do I have this done without breaking the “seal”?
Eaves are covered with foam. Should have I have him foam the edges of the duct end when he’s done?
