How Are Attics So Hot

The hot air rising from the lower floors of a building is often retained in attics further compounding their reputation as inhospitable environments.

How are attics so hot. Attics are known for their ability to heat so rapidly and leave you feeling breathless. A hot attic is bad for several reasons. So take a stand against attic heat by following a few simple steps. Alternatively install passive vents such as gable soffit and ridge vents which are openings in the roof that allow hot air to escape.

You have control over the temperature of your attic. Poor ventilation one of the most common causes of hot attics is a lack of adequate ventilation. Excessive heat deteriorates items you store in the attic and can cause moisture. However in recent years attics have been insulated to help decrease heating costs since on average uninsulated attics account for 15 percent of the total energy loss in average houses.

My idea is to vent the build up of hot air that has risen to the ceiling in the hotspot rooms into the attic so that air from cooler parts of the house can move in. But it is time to take away the heating power of the attic. High temperatures inside your attic shorten the life span of shingles. They have thermostats that turn the fan on at a recommended preset temperature of 100 110 degrees.

The top reason your attic is so hot is because of ventilation. Low cfm similar to a bathroom vent 300cfm and only in the hot spots basically by adding an inline ducting fan to the return ducts for the hotspot rooms.
