Owens Corning Raft-R-Mate attic vent is an extruded polystyrene foam vent designed to assure unrestricted airflow from the soffit to the ridge vent. Additionally, Raft-R-Mate attic vent has an optional bend down air stop or insulation block at the top plate of the wall in one easy-to-install product. The optional air stop or insulation block prevents loose fill 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. The Raft-R-Mate attic vents install quick and easily and are sized to fit 24 in., 16 in. and 12 in. on center framing. Utilize in both new and retrofit construction.
