There’s no doubt that attic ventilation makes your home more energy efficient. Damage from moister, and mold is prevented by good quality attic ventilation. It also stops ice dams from forming during the winter and extends the life of roof shingles.
Active vs. Passive Ventilation
Active Ventilation takes place when Electric fans are often used in the attic for ventilation, when electricity is not need, it is called Passive Attic Ventilation or PAV. Passive attic ventilation uses the natural air currents and the concept of convention to circulate air through the attic vents.
PAV is made in different styles depending on how your home was designed. One method is a fan that is attached to a central ceiling in the hallway and exhausts hot hair from the entire house upwards through the attic. In older homes natural PAV was placed between the roof and the wall. It is connected to a thermostat that runs on the fan when the attic reaches a set temperature. Clean Technology PAVs are solar-powered. PAVs might be unnecessary at times, our experts will help you to determine the need or the combination of needs for your home. However sometimes vents can be installed without any energy. Our Reliable Consultants can help you decide if your house has enough ventilation or if more vents should be installed. We also can point out wasteful and inefficient PAVs that can be removed.
