Pipe Penetration Open
The immediate space around this sewer vent pipe is completely open to the space below. We use closed-cell foam to seal this.

Sealed Pipe Penetration
Closed-cell foam used to seal up this air leak spot around the vent pipe.

Wires, too!
Wires coming through the plate/deck are an issue. We have to remember, air moves from less to more! Let's get this sealed up...

Wires Sealed
Done and done! We used our foam to seal around all wire penetrations.

Seal the Top Plate
The poly air barrier stops on either side of this wood plate. It is not properly sealed. We used our foam to correct that.
