  • Patent number: 4776262
    Abstract: Filtered insulation baffle that serves as a barrier against insects and other pests entering an attic space of a building while allowing free air to flow into the attic through the baffle. A housing is formed with closed sides and open ends and sized to fit into the area between adjacent rafters of the building. A filter is formed from a porous filter material that is sized larger than the open end of the housing and positioned in one end of the housing to allow the filter material to protrude from the housing. The baffle is positioned between the rafters with the filter material protruding into an opening between the roof deck and the plate structure of the building. The protruding filter material is then wedged into the opening such that a portion of the filter material will roll back on the end of the housing to seal the opening while allowing free air to pass through the baffle and into the attic space of the building.

  • Patent number: 4096790
    Abstract: A ventilation and insulation baffle is secured to the tops of the rafters in a building construction prior to placing the sheathing over the rafters to prevent insulation from blocking the soffit vents and to provide attic ventilation channels between the soffit vents and the attic. The baffle has a plurality of planar panels connected together by upstanding rectangular channels. The channels are spaced and sized to fit over the top of the rafters. The opposite free edges of each baffle have a half-formed rectangular channel to partially overlap the outer rafters and to support the panels therefrom. One edge of each of the panels includes an angularly disposed flap which is secured to the sill of the building to prevent insulation from entering the soffit from the interior of the building, but leaving an inner channel or passageway above each panel from the soffit into the interior of the structure.
