Attic Baffle To Cover Soffits Too

If your attic is well insulated the insulation might be plugging the spaces between rafters just above exterior walls.

Attic baffle to cover soffits too.

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. In this post we cover the intake ventilation. Can you have too much ventilation in your attic.

The attic roof vent baffles baffles hold the insulation away from the roof deck to permit air to enter the attic or under roof space. Finally to ensure that the airway to the vent remains open staple a ventilation baffle to the plywood sheathing in each rafter bay. Baffles are available at home centers. The answer is rafter venting.

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. 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. That is split into 4 25 square feet or 618 square inches for both intake and exhaust. Attic length x attic width 150 total vent space or net free area nfa my attic has an area of 1 288 square feet so my nfa is 8 5 square feet.

The solution is to add baffles which allow air to flow past the insulation photo 9.
