What Is Attic Insulation?
Attic insulation provides a thermal barrier on your attic floor. It can be made from a variety of materials with the most common form being batt (rolled blanket type) or loose fill (blown particles) insulation. These types of insulation are either blown into your attic or rolled. During the cooler months, the attic insulation prevents heated air from escaping and the cold outside air from infiltrating your home. When the hot air rises, the appropriate level of attic insulation will prevent the hot air from rising through the floor and into the attic. During the summer months, it prevent the superheated attic air from entering your home via the ceiling. This helps prevent your heating and cooling system from running around the clock to level the home’s temp to the temperature you have set. By far, appropriately insulating your attic can have a dramatic effect on not only your comfort but also your energy costs.
Facts About R Value That You Must Know
The term most often used when discussing insulation is ‘R-value.’ Simply put, this is just a measurement of the effectiveness of your insulation. The higher the R-value the better its insulating effectiveness. The Department of Energy states the “R-value depends on the type of insulation, its thickness, and its density.” Think of it similar to the rated batting inside of a jacket or sleeping bag. The thicker and higher quality batting insulates better, allowing you to stay warmer in frigid temps. Essentially, R-value measures how well your home will hold its temperature in and how well it will keep the outside temps from infiltrating your home.
Take a peek in your attic. If you can see your floor joists, you most likely need more insulation. Yes! Insulation can settle and reduce the value of effectiveness dramatically. Regardless of the type of existing insulation, it should be higher than the wood beams running across the attic floor to where they can’t be seen.
What Should My R-Value Be?
Depending on what area of the country you live in dictates the R value. Insulation in Kennesaw, Woodstock, and surround should be between R30-R60. Having a Guardian Expert measure your current R-value is a quick way to figure what your insulation needs are.
Why Would My Home’s R Value Decrease?
Recommendations can change over the years. Most importantly, your current insulation most likely has settled or is just not enough. Often times, homes are equipped with lower grade insulation that can quickly flatten rendering the R-value ineffective in keeping your home comfortable and sealed.
For example, blown insulation gains its effectiveness from the spaces between the particles. The air pockets actually do the insulating. The air stays warm during the winter and cool during the summer. When the blown insulation settles, it causes less room for the air pockets to do their job. However, the benefits of blown insulation is that it can get into all the nooks and crannies that others types of insulation may not.
Case in point; batted insulation. It may not cover all the areas in your attic which allows temperature variances and air seepage. Again, creating an environment for discomfort in your home due to the mixing of air. Batted insulation rolls between the joists. However, it is not flexible in getting into all of the crevices that require the necessary thermal barrier. Adding insulation to the top of your batted insulation can provide dramatic results. Preferably, blown insulation to get into the nooks and crannies that are lacking.

When comparing blown fiberglass attic insulation to others, the benefits are clear to be seen. Rolled batt insulation is known to offer the poorest of efficiency and temperature control. Cellulose blown insulation performs reasonably well. However, it is very dusty and inconvenient to install. Spray foam (closed and open cell) has become recently popular. There are quite a few negative key points that can counteract the high efficiency level of this type of insulation. Pests such as termites, bugs, and critters can bore holes into the foam insulation which go unseen until the infestation is often extreme. Same goes for moisture control. In some cases with the closed cell, roof and wall leaks can go undetected until the wood rots through with severe damage. For example, roofers have been known to negate this type of insulation citing no indication of roof damage from storms due to the water barrier of the insulation. The choice is clear!
