Vented or non-vented deck skirting in this situation is the question. We are replacing our PT deck boards with Azek boards and screen room above. The deck is about two feet above bare soil. It will have a deck skirt of vertical soffit. Camo fasteners leave a gap between boards. Will that gap be enough to vent moisture beneath such that I do not need vented skirting? If not then I vent the skirt but need insect screen beneath the azek to keep the screen room a screen room
