Allow Air To Flow Into Attic

This is normally the point where air enters your attic.

Allow air to flow into attic.

That means air can t flow from the soffit vents to the roof vents. Taking advantage of this natural process referred to as passive ventilation is the most common way to vent an attic. Hot air exhaust vents located at the peak of the roof allow hot air to escape. In the summer natural air flow in a well vented attic moves super heated air out of the attic protecting roof shingles and removing moisture.

Baffles or rafter vents are a styrofoam chute designed to allow air flow into an attic space when the airflow at the soffits have been obstructed. The narrow soffit slits allow air to flow freely into your attic. Ridge vents are available in a series of pieces or as one long piece. If your attic is well insulated the insulation might be plugging the spaces between rafters just above exterior walls.

Attic ceiling to stop airborne moisture from reaching a cold surface and condensing inside the building envelope in this design insulation effectively separates the interior and exterior spaces while slowing down moisture flow so the dewpoint is not achieved within. Baffles are available at home centers. They are a proven and cost effective solution for improving air intake in many homes. Proper insulation and air sealing also keeps attics cold in winter by blocking the entry of heat and moist air from below.

The airflow pushes the hot air out which is exactly what you need to keep your attic cool during the summer. In addition insulation baffles must be installed at the point where the attic floor meets the roofline to prevent the attic insulation from migrating into the cavities and restricting the airflow from the soffit vents. Baffles or rafter vents are an ideal choice for improving intake venting. The insulation will resist heat transfer into the house.

Make sure there is air flow from the eaves. Unvented attic assemblies unvented attics rely on an air impermeable insulation installed to the roof deck s underside i e. If the soffit of your home isn t perforated to allow air movement either replace it with perforated soffit or install round air vents under the eaves to allow air flow.
