ABSTRACT:
In a house structure in which insulating material is to be laid in between and over the attic floor joists, an insulation vent is provided in spaced relation to the roofing boards to allow for free flow of ventilating air between the soffit and the interior of the attic above the insulating material and along the roof boards. This insulation vent is sold flat. To be installed it is folded on pre-scored crease lines, first to form an elongated trough consisting of a rectangular roof clearing sheet and two upwardly extending roof contacting spacer flanges. A lower end portion of the roof clearing sheet is folded down to become a wall sheathing contact sheet, and the flanges which fold down with it are stapled to the roof rafters to hold the roof clearing sheet and sheathing contact sheet in place. The upper end of the roof clearing sheet is folded down also on a pre-scored crease line to form a stiffener tab for the upper end portion of the roof clearing sheet and the two flanges folding down with it are stapled into the roof rafters to permanently position the stiffener tab under the upper end of the roof clearing sheet and to hold the upper end of the roof clearing sheet in position with the roof clearing sheet spacer flanges held against the roof boards.
