What is ventilation?

Vents are openings in the attic area that allow lost heat and moisture to escape. If you don’t ventilate properly, water vapour can condenseand collect on insulation and rafters. This will reduce the effectiveness of the insulation and could damage the house. We install cardboard and Styrofoam morvents to provide adequate ventilation. Morvents are attic roof vent baffles that hold the insulation away from the roof deck to permit air to enter the attic or under-roof space. The morvents are installed at the eaves or soffit area. Morvents should be installed between every other rafter. The roof should also be vented at or near the peak or at the gable ends. This ensures a flow of air from the eaves and exhausts at the ridge. Morvents are also called rafter vents and chute vents. Without ventilation, attic heat could penetrate into living areas during summer or heat the roof during winter causing ice dams.
