Did you know that proper attic ventilation and insulation can make an enormous difference to your home’s energy efficiency and your power bills? Virginia insulation and ventilation systems should keep your attic’s temperature no more than 20 degrees higher than the temperature outside in the summer. During the winter, on the other hand, your attic shouldn’t be warmer than the outdoors. If it is, that means you’re paying to heat an unused space.
When evaluating your attic’s ventilation and insulation, you should use a remote thermometer to establish when the temperature changes within the space and by how much. Counting on a ventilation system that relies on moving parts that can break (such as turbines and fans) is not a great idea. It’s much smarter to use a properly installed soffit and ridge system to vent your attic.
Consider hood vents if your home has a hip roof with no or few ridges. If you choose this type of ventilation, make sure that enough vents are installed. These systems work by allowing the hot air to exit your home through the hood vents. The soffit vents pull cool air in from the outdoors to replace the escaped hot air. This process should take place no less than 12 times every hour. By measuring the volume of the air your attic holds, a contractor or roofer can determine the correct number of hood and soffit vents you need in your attic.
The ideal insulation level for an attic in Virginia is R-38. This means approximately18 inches of foam insulation. If the insulation in your attic is old and worn, you should be aware than adding a new layer to it will not result in a properly insulated space. The air within the insulation is crucial to its functionality, and aged, broken-down material cannot contain the air it needs to work correctly. It can be expensive to have worn insulation removed from a home entirely, but it’s worth the investment, because doing so will save on energy costs in the long run.
Your insulation should never block your soffit or intake vents. There are times when it’s best to just remove the soffit vents and allow the air to circulate without restrictions.
Virginia insulation experts can help you assess your attic and optimize its energy efficiency. If you’re ready to improve your attic and shrink your energy bills in the process, there’s no time like the present.
