attached is a picture of the valley-rafters cavities that aren’t vented much. Although furring strips are in, ventilation isn’t adequate especially at the valley-beams. They’ve drilled holes at the blocking in the upper part to let air out, but the solid Valley beam LVL isn’t allowing air in. As a solution, although not perfect, would be to have holes drilled in the web of the I-joist rafters to allow a maximum of airflow. Provided the structural engineer is on board with drilling the web.
Any suggestions or solutions?
BCBC2018 requirements are :
-1:150 ratio
-min 25% air vented from the bottom.
-min 25% air vented through the top.
Thanks a bunch
