Attic Baffle To Cover Soffits Too

The answer is rafter venting.

Attic baffle to cover soffits too.

We use this same design under roofs that cover cathedral ceilings but on occasion find that more air space and air flow up under the roof sheathing are needed in those structures. Run baffles the entire length of the rafter bay from the soffit vent to the ridge vent then add batting insulation over the baffles. If you opt not to have an attic baffle you could potentially be leaving your home to additional debris and moisture to enter through the soffit vents. That means air can t flow from the soffit vents to the roof vents.

The molded polystyrene baffles available at home centers and lumberyards for about 1 each form channels that hold insulation at bay and direct incoming air upward. Finally to ensure that the airway to the vent remains open staple a ventilation baffle to the plywood sheathing in each rafter bay. The solution is to add baffles which allow air to flow past the insulation photo 9. If your attic is well insulated the insulation might be plugging the spaces between rafters just above exterior walls.

Rafter vents or insulation baffles install in any rafter space to create narrow gaps that direct fresh air from the soffit vents to the peak of the roof. Can you have too much ventilation in your attic. In this post we cover the intake ventilation. Baffles are available at home centers.

If this does happen the soffit vents will not function as best as they should and therefore supporting the formation of mold or fungi rather than preventing it.
