ABSTRACT:
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.
