Why You Need Your Attic Properly Insulated
Attics are notorious for reducing the energy efficiency of a home. In the winter a great deal of the home’s heat rises and gets into the attic which means that it’s not available for the rest of the home. In the summer it is remarkable how much heat from outside can come into the attic that is uninsulated making temperatures rise sometimes to 120 degrees Fahrenheit or more. Because energy costs are rising it is a terrible waste of money to allow this and other areas of the home to remain uninsulated or to have insulation that is inadequate.
Spray foam and blowing in insulation are among the best types of insulation you can use in an attic. This type of foam insulation typically comes with a substantially higher R-value than other types that might be used. Depending on what you select, it could be an R-value of 6.2 or higher. One of the great points about using this type of insulation is the fact that the foam creates an air seal. It is much better suited for filling the gaps and cracks that are found in many areas.
In fact, this type of foam is even sometimes used as a spot treatment for air sealing the areas in an attic. When it is used in larger amounts it completely eliminates the need for any other type of insulation. Depending on the type of spray foam that you use, it can also prevent the buildup of moisture. Because this type of insulation can cover even the cracks and gaps means that it significantly improves your home’s energy efficiency.
The typical homeowner is very surprised to learn that even if as little as 5% of areas in an attic are not protected properly by insulation, then it can reduce the overall performance by up to 50%. Some types of insulation are almost impossible to put in perfectly and this means that some areas are unprotected. The easy way around this is by using spray foam insulation.
