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.
