Owens Corning Raft-R-Mate 22.5 x 48 inch Extruded Polystyrene Attic Rafter Vent with Optional Air Stop 510266

Owens Corning Raft-R-Mate attic vent is an extruded polystyrene foam vent designed to ensure unrestricted airflow from the soffit to the ridge vent. Additionally, Raft-R-Mate attic vent has an optional bend-down air stop/insulation block at the top plate of the wall. The optional air stop/insulation block prevents loosefill insulation from filling the eave space during installation of cathedral ceiling or attic floors, by closing off the opening below the Raft-R-Mate attic vent to the soffit. It also helps to prevent "wind wash", which can cause attic insulation to be blown back off of the top plate, causing unwanted heat loss around the perimeter of the attic.
