Few things are more misunderstood about the home than attic ventilation. In essence, all ventilation is about circulating air to keep it fresh and to reduce moisture levels. The American Institute of Architects estimates that 90 percent of homes in the U.S. have unacceptably high levels of moisture. For most of us, the attic is a place to store clothes, luggage and old family photos, but for energy researchers it's a hot topic of discussion. In the last several decades, building codes have called for increased attic insulation. Proper attic ventilation here in the Chicagoland area is necessary as we experience both cold and warm temperature extremes. Most experts contend that a well-ventilated attic keeps the house more comfortable in summer and guards against moist, heated air building up in winter. A healthy airflow also helps with ice dams, which begin to form when warm air in the attic melts the snow from beneath and creates runoff that refreezes on the colder eave. In summer your attic can reach 150 degrees Fahrenheit and you need proper ventilation to remove the heated air thus, lower your air conditioning bills significantly. Attic ventilation come in many types, sizes, shapes, powered or static, and even solar powered. The main types of ventilation are roof mounts, peak mounted, and soffit mounted. The peak & roof mounted vents allow for rising heated air to escape, while soffit vents allow cooler air to be drawn into the attic space.Call us today, to evaluate your current ventilation strategies, and make suggestions on how to improve your airflow.
