Filtered insulation baffle

Details

Attorney, Agent or Firm: Silverman, Cass, Singer & Winburn, Ltd.

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.

DETAILED DESCRIPTION The disadvantages of prior art ventilators are overcome in accordance with the present invention by providing a baffle or ventilator that can be utilized in conjunction with the soffit ventilator and roof ridge ventilator or other roof ventilators.
The baffle has a housing with closed sides and open ends.
The housing, sized to fit into the area between adjacent rafters of a building, is provided with a porous filter material sized larger than one open end of the housing and positioned to protrude from the housing.
The baffle is placed between adjacent rafters and the protruding filter material is wedged into an opening between the roof deck and the plate structure of the building to force a portion of the protruding filter material to roll back on the end of the housing thus sealing the opening against insects and other pests while allowing free air flow through the baffle and into the attic space of the building.
