Attic Exhaust Fans Vs Ridge Vents

One of the leading causes for fires.

Attic exhaust fans vs ridge vents.

Do not use mechanical means electric attic fans. Taking advantage of this natural process referred to as passive ventilation is the most common way to vent an attic. Without ventilation unfinished attic spaces can end up having stagnant air. In the case of ridge vents when heat builds up inside the attic it makes sense that there should be a means of moving the hot air out other than relying on natural ventilation especially if there is little to no air movement outside.

What makes ridge vents so effective is how they run the length of your roof. One insists on using the ridge vents with no exhaust and the other sides with the use of exhaust fans. A ridge vent is a passive system and offers less air movement and in moderate climates this style tends to be sufficient. As warm air rises in your attic fresh air is drawn in through soffit vents.

Like attic fans ridge vents are designed to exhaust air that is already inside the attic. More than 50 of the attic fans i see do not work and have current still live to the motor. For optimal performance ridge vents require soffit venting to bring air up and out the top of the roof. That depends on your roof.

In more extreme climates one or more turbines will provide better circulation. Ridge vents are an ideal solution to ventilation in an ideal attic. Which is better for your roof. Ridge vents are a passive system simply allowing hot air to rise up through them rather than pushing it out as a fan does.

A ridge vent or a solar attic fan. Hot air exhaust vents located at the peak of the roof allow hot air to escape. Best ventilation is open soffit venting to a open vented ridge vent. In a properly designed passive system air enters through the soffit vents rises by convection in the attic and exits through the vents in the roof or gables.

This is different from soffit vents which allow air to travel into the attic. Ridge vent vs solar attic fan.
