A method for insulating and ventilating a space between rafters for supporting a roof includes, an elongated insulation mat having an integral baffle, at least one channel on a roof facing side of the baffle for passage of ventilating air, and at least one vapor permeable membrane covering at least a portion of the insulation mat facing the channel, wherein each vapor permeable membrane transmits water vapor emanating from the insulation mat.

Insulation batt having integral baffle vent

A baffled insulation product for ventilating air under a roof from an open space is provided comprising an elongated insulation mat having top and bottom major surfaces, the top major surface facing the roof when the product is installed in the open space, the insulation mat having a baffle integral therewith proximate to the top major surface, comprising at least one airflow channel for the ventilating air.

A shingle and a method of applying the same to a roof is disclosed, in which the shingles are wind-resistant, opposing being torn from a roof by wind or the like. The shingles each include a pair of vertically spaced-apart lines extending horizontally across the lower ends of butt portions of the shingles, with at least a lower-most line being a line of sealant, and defining between the vertically spaced-apart lines a fastener zone, which fastener zone may have fastening spots therein that, in turn, may define a fastening line. When shingles in accordance with this invention are applied to a roof, the line of adhesive connection between tab portions of shingles in an overlying course are secured to lower ends of butt portions of the shingles of a subjacent course, sufficiently low below the tab portions of shingles, as to preclude any significant engagement by wind or the like that may tend to lift the tab portion off the sealant line. Additionally, the person applying shingles to a roof is directed where to apply the fasteners, so that a greater number of fasteners secure a given shingle to the roof.
