Cash in the Attic
The attic is not considered to be a part of the home that is interesting. It has commonly been known as a good place for storage. But in today’s energy driven environment, it literally has become a place that can create “cash in the attic”. The most common mistake homeowners make when installing insulation is to block the flow of air at the eaves. It is always a good idea to use rafter vents to maintain airflow.
Attic fans are designed to cool hot attics by drawing cooler air from the outside through attic vents and pushing the hot air out. If the vents are blocked and not sealed, the attic fans will suction the cool air up out of the house into the attic. This will use more energy and make your air conditioner work harder, which will increase your summer utility bill. It is a good idea to make sure that the attic is well-ventilated using passive vents and natural air flow. At first it may seem odd to add insulation for warmth and then purposely allow cold air to enter the attic through vents, but this combination is the key to a durable and energy-efficient home. Proper insulation and air sealing also keeps attics cold in winter by blocking the entry of heat and moist air from below. In the summer, natural air flow in a well-vented attic moves super-heated air out of the attic, protecting roof shingles and removing moisture.
Another energy saving idea is to completely cover your attic floor with insulation out to the eaves you need to install rafter vents. Complete coverage of the attic floor along with sealing air leaks will ensure you get the best performance from your insulation. Rafter vents should be placed in your attic ceiling in between the rafters at the point where your attic ceiling meets your attic floor.
When it comes to energy savings, many often resort to solar energy as an alternative. Light solar attic fans reduce heat build-up in your attic and can minimize the load on your HVAC system. Solar attic fans are available for all roof types; solar attic fans install easily with no electrical wiring or structural changes and blend seamlessly into your roof line. The function of a solar attic fan is to improve attic air circulation resulting in a healthy, energy efficient home. Solar attic fans pull hot air and moisture out of your attic extending the life of your roof, as well.
Homeowners spend plenty of money on windows, insulation, and roofing to reduce the cost of energy. Adding an attic fan to the equation certainly appears to be a feature that will result in “cash from the attic”.
