Abstract
A roof ventilation baffle comprising a pleated or corrugated membrane forming a plurality of air passages. The baffle is installed between the underside of the roof sheathing and the upper surface of fiberglass insulation bats with the pleats parallel to the rafters or roof joists to provide ventilation, along the underside of the roof sheathing. The ventilation baffle is also applicable to outside walls and floors over unheated or uncooled spaces. The baffle may be perforated to provide air flow between the air passages formed by the pleats and to permit any moisture trapped in the insulation to evaporate into and be removed by the air flow through the channels.
