Radiant baffle/collector for roof construction and retrofit

In a baffle vent designed to be positioned against the underside of a roof between adjacent roof rafters and defining an air flow passage between the baffle vent and an interior surface of the roof for directing air from a soffit area to the roof upwardly over the interior surface of the roof, the air flow passage having a first end with an opening below the roof for admitting air into the air flow passage and a second end with an opening longitudinally spaced from the first end, the improvement wherein the baffle vent consists of:

• an elongated self-supporting structure consisting of sheet material having opposite longitudinal ends and opposite transverse side edges and an upper and a lower surface,
• wherein:
• the baffle vents are self-supporting by flexing the opposite transverse side edges upward and against adjacent roof rafters such that the baffle vents stay in place without the use of mechanical fasteners;
• the upper and lower surfaces of the baffle vents are uncovered and exposed when the baffle vents are self-supported to adjacent roof rafters;
• the baffle vents have a cross-sectional shape that extends to and between the transverse opposite side edges that is and continuously concave upwards in a direction from the lower surface of the baffle vents toward the upper surface of the baffle vents;
• and
• at least one of the upper and lower surfaces of the baffle vent is reflective.
