| just board it then. i would still use vapour board to be safe and check for cross joist airflow. |

| a cheaper way is to drill 3/4" holes along the centre of the joists. this will not weaken the joists and it will sort out the crossflow. just make sure you have vents front and back. |

| That sounds like a good idea, what something like 2 or 3 holes in each joists or something? I have a vent at the front but at the backthere is a untility roof and the joist going the other way to the main garage and there is no vent there. What is the best way to put a vent in? |
