A baffle board (10) is disclosed for being mounted between the roof and ceiling of a room to provide ventilation along the underside of the roof and to prevent insulation between the ceiling and roof from being disturbed by air currents. Baffle (10) includes a sheet of stiff, relatively thin material (11) having outwardly and longitudinally extending side tabs (12, 13) defined by respective, perforated lines (12a, 13a). Side tabs (12, 13) are adapted to be folded at substantially right angles to the sheet and fastened to the inner facing surfaces of adjacent roof rafters. Sheet (11) also defines on one end thereof an end tab (14) defined by score lines (14a, 14b, 14c). End tab (14) is adapted to be folded back under sheet (11) and fastened to the top plate of the exterior wall.

In a roof and ceiling construction of a building wherein the ceiling is formed by a plurality of spaced-apart ceiling joists mounted on the top plate of stud walls and the roof is formed of a plurality of covered, inclined; spaced-apart roof rafters intersecting the ceiling joists proximate to the stud wall, the combination therewith of a baffle board for mounting over an exterior wall between the roof and ceiling of a building to provide ventilation along the underside of the roof and to prevent insulation between the ceiling and roof from being disturbed by air currents, said baffle board comprising: (a) a sheet of stiff, relatively thin material having an outwardly and longitudinally extending side tab integrally formed on opposite sides thereof and defined by respective, perforated lines in said sheet, whereby said side tabs adapted are folded at substantially right angles to said sheet and fastened to the interfacing surfaces of adjacent roof rafters; (b) said sheet also defining on one end thereof an end tab having a width substantially equal to the width of the sheet with side tabs folded at right angles thereto, said end tab defined by a score line and not by slits between said end tab and said side tab, whereby said end tab is folded back under said sheet and fastened to the top plate.
