Allow Air To Flow Into Attic

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.

Allow air to flow into attic.

Baffles or rafter vents are an ideal choice for improving intake venting. Taking advantage of this natural process referred to as passive ventilation is the most common way to vent an attic. Proper insulation and air sealing also keeps attics cold in winter by blocking the entry of heat and moist air from below. 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.

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. The narrow soffit slits allow air to flow freely into your attic. 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. Make sure there is air flow from the eaves.

The airflow pushes the hot air out which is exactly what you need to keep your attic cool during the summer. That means air can t flow from the soffit vents to the roof vents. This is normally the point where air enters your attic. Baffles are available at home centers.

The insulation will resist heat transfer into the house. The solution is to add baffles which allow air to flow past the insulation photo 9. Hot air exhaust vents located at the peak of the roof allow hot air to escape. Ridge vents are available in a series of pieces or as one long piece.

Unvented attic assemblies unvented attics rely on an air impermeable insulation installed to the roof deck s underside i e. The soffit vents allow convective air movement from the soffits of the residence to the ridge vent. 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.
