Is Your Attic Properly Insulated? Here's How to Tell

When it comes to assessing the insulation in your attic, the first step is to take a look at the other side of the attic. If the insulation is at the same level or below the attic floor joists, you likely need to add more insulation. On the other hand, if you can't see any of the floor joists because the insulation is way above them, you probably have enough and adding more insulation may not be cost-effective. The United States Department of Energy (DOE) recommends having between 13 and 18 inches of insulation so that an attic is properly insulated.

This means that if your attic has obstructions, you may not be able to install blocks; the insulation of the blocks also does not provide a vapor barrier. However, the DOE recommends that attics in southern homes be insulated with at least 13 to 14 inch (R-38) insulation. An attic with inadequate insulation can lead to uncomfortable temperatures, as it lacks the thermal barrier that a house needs between the living room and the attic. Every home is different and may require different services to ensure the most effective way to insulate an attic. To determine if your attic has enough insulation, you should first check if it meets the DOE's recommended levels.

If it does not, you may need to add more insulation. If your attic has obstructions, you may need to use blocks or other materials that provide a vapor barrier. Additionally, attics in southern homes should have at least 13 to 14 inch (R-38) insulation. Ultimately, having enough insulation in your attic is essential for keeping your home comfortable and energy-efficient.
