A well-ventilated attic has undereave or soffit vents, which allow fresh air into the attic. The fresh air flows up between rafters to the ridge, where a ridge vent, roof vents or gable vents allow the air to exit. But if insulation is allowed to bunch against the inside slope of the roof between the rafters, air will be blocked before it can traverse the attic. RAFT-R-MATE® attic rafter vents create a space between each rafter for air to flow freely up the rafters and into the attic.
