Allow Air To Flow Into Attic

They are a proven and cost effective solution for improving air intake in many homes.

Allow air to flow into attic.

Baffles are available at home centers. The soffit vents allow convective air movement from the soffits of the residence to the ridge vent. 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.

That means air can t flow from the soffit vents to the roof vents. Make sure there is air flow from the eaves. These are exhaust vents that are installed on the ridge of your roof i e. This is normally the point where air enters your attic.

Baffles or rafter vents are an ideal choice for improving intake venting. The solution is to add baffles which allow air to flow past the insulation photo 9. If your attic is well insulated the insulation might be plugging the spaces between rafters just above exterior walls. 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. 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 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. 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.

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. The insulation will resist heat transfer into the house. Unvented attic assemblies unvented attics rely on an air impermeable insulation installed to the roof deck s underside i e.
