The Energy Efficient Attic -- Ventilation

Ventilation

Keep a Cooler Attic in the Summer, Remove Moisture in the Winter, and Prevent Heat Build-Up.

The Energy Efficient Attic^® properly ventilates your home by pulling air through soffit and ridge vents located in the attic. Then, to pull air out, wind or natural convection goes through the ridge vents and replaces air through the soffits—all without any moving parts and without consuming any energy. We also may use a variety of other ventilation systems in your home such as wind turbines and air hawks.

The ventilation system we use in the Energy Efficient Attic^® prevents heat build-up in the warm months and can reduce stress on your cooling system. In colder weather, the system prevents moist air from your laundry, showers and cooking appliances from becoming trapped in roofing and insulation.

Proper attic ventilation also helps insulation and radiant barrier spray to perform at a higher efficiency. With a well-ventilated home, you can stay comfortable, reduce energy consumption, and prevent damage to your home.

Frequently Asked Questions

Is an airtight home an energy-efficient home?
While sealing unwanted air leaks helps energy efficiency, it’s best to combine it with controlled ventilation in your attic to manage your energy costs.

What’s energy efficient about attic ventilation?
A ventilated attic is cooler in the summer and drier in the winter. Attic ventilation systems accomplish this by exhausting heated air from the attic—keeping the rest of the house cooler and using less energy. Ventilation systems also prevent moisture in colder months, thereby limiting the chances of serious roof damage.

What causes moisture in the attic?
Three to five gallons of water vapor a day comes from showers, laundering and cooking appliances. That water vapor can get trapped in the attic and cause your home to suffer from roof damage that could void your home warranty.

What are some ventilation systems that you recommend?
A ridge vent at the peak of the roof and vented soffits under the eaves are what we use as part of the Energy Efficient Attic^® solution. Your home’s needs may differ depending on your roof. Some systems we’ve used in the past include electric and solar-powered vents, wind turbines and air hawks.

What does a ridge vent system do?
A ridge vent system creates areas of high and low air pressure. The process works by first pulling out air in the attic through the ridge vent, which is then replaced by air flowing in through the soffit vents. On calm days, the system allows the hot air to go up and out of the house, with cooler air being drawn in through the soffits.
