ROOF VENT

摘要

A roof vent for ventilation of a roof, the roof vent adapted to be placed on the pitch of the roof, not the ridgeline. The roof vent has a flat or tabular floor and a base attached to the floor. The floor includes a throat member having vertical walls and the base has sloped back lower walls, and upper walls that are non-horizontal and slope back from the lower walls, and finally a horizontal top. The effect of the nonnormal lower walls and the sloped back upper walls, in conjunction with a typically rectangular flat (parallel to the floor) top provides an airfoil shape to the roof vent that assists in the flow of an over the roof vent.
