An insulation stop and ventilation baffle article is described for assisting in the installation of loose fiber or particulate thermal insulation in the crawl space or attic between a ceiling and roof of a building structure. The article is constructed of a rather stiff sheet material having parallel side fold lines formed therein adjacent to and spaced inwardly from parallel side edges. The fold lines define side sections that may be folded upwardly to receive the ends of an elongated flexible rod. Clamp members are slidably engageable over the ends of the rod to slide inwardly and contact the side sections and hold them in an upwardly folded condition. The length of the rod is slightly greater than the corresponding horizontal distance between roof rafters. Also, the distance between the fold lines is slightly less than this rafter spacing. Therefore, the article may be inserted between the rafters with the ends of the rod engaging the rafters and causing the rod to bend along its length. The spring action of the rod will operate against the adjacent rafters to hold the article in place relative to the plate of an adjacent exterior wall and the roof sheeting while insulation is blown into the area against the inwardly facing surface of the baffle. The baffle will prevent seepage of insulation into the air passage leading to ventilators in the eaves and allow a maximum buildup of insulation above the exterior wall plates.

A combination insulation stop and ventilation baffle for mounting over an exterior wall and between a roof and ceiling of a building structure to provide a ventilation passageway to an air space between the ceiling and the roof and to prevent insulation which is subsequently applied to the ceiling from clogging said passageway, in which the exterior wall has a bearing plate on which ceiling joists and inclined parallel roof rafters are supported, said rafters being spaced from each other a first predetermined distance and said roof and bearing plate being spaced from each other a second predetermined distance, said combination insulation stop and ventilation baffle comprising: a body of stiff sheet material having (a) a length dimension between end edges greater than the second predetermined distance, and (b) a width dimension between side edges greater than the first predetermined distance; said body having parallel side fold lines formed therein adjacent to and spaced from the side edges defining side sections between the side fold lines and the side edges and a central section between the parallel side fold lines in which the distance across the central section between the side fold lines is slightly less than the first predetermined distance to enable the side sections to be pivoted relative to the central section and the body inserted between two rafters over the exterior wall, with the side sections bearing against the rafters and one end edge operatively engaging the bearing plate, the remaining end edge projecting into the air space to define a ventilation passageway; an elongated rod of a length dimension greater than said first predetermined distance extending across the width of said body and having opposite ends projecting through said side sections; clamp members receivable on the rod ends and selectively positionable thereon for engaging the side section to hold them in a selected angular relationship to the central body section.
