Blower door test
I recently built myself an ICF home, approx. 2,500 s.f. x 2.
I used ICFs from footer to roof and insulated the attic with approx. 10” of open-cell sprayed on the rocked ceiling. I was diligent about foaming all possible leak points.
I had a blower door test done and was told at 50 pascals it had a natural ach of .04. Does this seem possible?
It seems extremely tight!
I did install a stand-alone HRV system. Will this provide the make up air I need for dryer & range vent? The HRV is set up to provide ventilation for baths and pantry. My understanding was the HRV provided a balanced system. Will this throw it out of balance when a vent is running?
We did use the Flir camera and found very few leaks. I am in zone 5.
