Abstract
A thermal break ventilator unit designed to extend between the opposed end jambs of a window frame. The thermal break ventilator unit has a box-shaped body with a ventilating passage therethrough. Essentially cylindrical, opposed raceways are attached to the opposed end jambs within the box-shaped body. A substantially drum-shaped closure unit rotates within the opposed raceways. The closure unit has a closed position wherein the ventilating passage is closed and an open position wherein the venilating passage is substantially unrestricted by the closure unit. Structural heat transfer barriers are incorporated into the metallic parts of the thermal break ventilating unit and are so located that, when the closure unit is in its closed position, there is no continuous, metallic path by which heat can flow between the interior and exterior parts of the ventilator unit.
