Attic Air Ventilation System

In the winter warm moist air seeps into the attic from the living space below.

Attic air ventilation system.

It comes on an easy to install flexible mesh roll and is hand nailable with no complicated fitting wrapping nail gun adapters. In essence all ventilation is about circulating air to keep it fresh and to reduce moisture levels. Good ventilation allows the heat and moisture to escape. In the summer good attic ventilation reduces heat buildup.

Attic ventilation serves two main functions. Attic fans are intended to cool hot attics by drawing in cooler outside air from attic vents soffit and gable and pushing hot air to the outside. In short an adequate and balanced ventilation system is one that allows an equal amount of air to enter and exit the attic area. It is the recommendation of the ravc that the attic ventilation system always is balanced.

To lower attic temperatures and to remove excess moisture. Intake vents located at the lowest part of the roof under the eaves allow cool. Lowering the temperature in the attic can help reduce air conditioning energy costs and roof deck temperature optimize the service life of a roof covering and minimize ice damming. That keeps your attic dry and reduces ice dams.

When installed as part of a properly balanced when installed as part of a properly balanced attic ventilation system gaf cobra exhaust vent is a shingle over exhaust vent installed at the roof ridge that helps exhaust excess heat and moisture from your attic. The exact number of intake and exhaust vents your roof needs is figured based on the square footage and volume of the attic area. Air follows the path of least resistance. A home s ventilation system consists of everything from roof vents to the best attic fans without the right roofing and attic ventilation system your home can become uncomfortable and cost more to cool or heat.

About 90 percent of homes in the us have unreasonably high levels of moisture. In a properly designed and installed attic ventilation system that means the air will flow from the intake vents to the exhaust vents flushing out the warm moist air along the entire underside of the roof deck. Plus roofing and attic ventilation systems can protect homes from the expensive roof and structural damage caused by trapped heat ice dams moisture and mold. That cuts cooling costs and prolongs shingle life.

Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents.
