I had prided myself on the joy I get from insulating and my ability. If you look at the left side of the air chute, you see a gap in the insulation. This gap is over the wall plate. Now, I have two wall plates, so it is not as critical as if I had only one, but it is still a reduction in insulation, left behind by the proud insulator. Also, I suppose to save money, I cut the proper vents in half. Proper vents are very cheap. I reduced the air flow by half in each truss cavity. When I added these in to the new garage, I used full width air vents for maximum air flow above the insulation dam as seen in photo 5.
