Owens Corning Raft-R-Mate 22.5 in. W X 48 in. L Unfaced Cavity Attic Rafters Batt 7-1/2 sq ft

Raft-R-Mate attic vent is a rigid polystyrene sheet shaped to create a ventilation path/cavity between the insulation and the roof deck. Raft-R-Mate attic vents help ensure that the insulation does not block the air flow path. Inadequate ventilation may lead to excess heat and moisture build-up in the attic or rafter cavity. These conditions can lead to the deterioration of the roofing materials and deck, insulation, structural framing members, or interior ceiling finishes. Helps prevent the attic or rafter cavity insulation (batt of blown) from expanding to fill cavity airways and restricting airflow., ,
