Attic Air Ventilation System

In the summer good attic ventilation reduces heat buildup.

Attic air ventilation system.

About 90 percent of homes in the us have unreasonably high levels of moisture. That cuts cooling costs and prolongs shingle life. In essence all ventilation is about circulating air to keep it fresh and to reduce moisture levels. It comes on an easy to install flexible mesh roll and is hand nailable with no complicated fitting wrapping nail gun adapters.

Attic ventilation serves two main functions. In the winter warm moist air seeps into the attic from the living space below. 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. Attic ventilation works on the principle that heated air naturally rises primarily utilizing two types of vents.

Intake vents located at the lowest part of the roof under the eaves allow cool. 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.

This means an equal amount of intake net free area through vents positioned in the soffit overhang or near the roof s lowest edge and exhaust net free area through vents installed at or near the peak of the roof.

Air follows the path of least resistance. Understanding whether your home could benefit from some form of attic ventilation might just be if not a life saver a roof saver. However if your attic has blocked soffit vents and is not well sealed from the rest of the house attic fans will suck cool conditioned air up out of the house and into the. In short an adequate and balanced ventilation system is one that allows an equal amount of air to enter and exit the attic area.

The exact number of intake and exhaust vents your roof needs is figured based on the square footage and volume of the attic area.
