which a different configuration of the air flow channels is shown the upper air flow channel 14 remains substantially the same but the lower air flow channel is separated into two sections 17 a 17 b other than the separation of the lower air channel into two sections the insulating member 10 remains in the same configuration as described above the alteration of the lower air channel into two sections 17 a 17 b is intended to be exemplary of any number of air flow channels that can be cut through the insulating member 10 to provide for additional flow of air through the attic space 50 the number and size of the air flow channels is dependent solely upon the dimensions of the insulating member the depth of the ceiling joists and the incline of the roof rafters what has been described above is the configuration of the insulating member 10 that is configured to fit within the roof trusses 44 and ceiling joists 32 that directly overlie one another ones that are not offset or u201c sistered u201d next to each other as they meet over the exterior wall 38 in the event that the roof trusses 44 and the ceiling joists 32 are offset then the space between adjacent framing structures creates a lower rectangle and an upper rectangle.
