About Attic Ventilation and Insulation
Attic ventilation is a critical component of an energy-efficient home. It prevents heat buildup in the summer and air moisture accumulation in the winter (which can lead to mold, ice dams and deteriorating roof materials). Proper attic ventilation combined with insulation and proper air sealing helps keep your home comfortable and protects against costly structural damage. Go here https://palomoinsulation.com/
In general, unfinished attics should be vented. Ventilation promotes air flow, which cools the attic and helps lower cooling costs. In addition, a well-ventilated attic can help reduce indoor humidity, reducing the need for additional air conditioning and improving the comfort of living spaces.
Attic Ventilation and Insulation: Why Both Matter for Energy Efficiency
A properly-sized and installed attic ventilation system consists of intake vents (usually located in the soffit) and exhaust vents (usually located on the ridge or roof gables). A combination of soffit and ridge vents is often preferred, as it provides a steady and consistent flow of air.
Attic ventilation can be enhanced with a reflective roofing material. This helps reflect the sun’s rays and keeps the attic cooler. Insulation also improves attic ventilation, allowing more of the cool air to flow down into the house and keeping hot air out. Proper attic ventilation and insulation are most effective when paired with proper air sealing. This involves identifying and sealing air leaks between the living space and the attic, which can significantly reduce energy use and improve comfort and indoor air quality. In addition, a proper air-sealing system can help increase the effectiveness of attic insulation, reducing the amount of energy needed to maintain a desired indoor temperature.
