Winter is just around the corner and one of the major contributors to home energy efficiency is insulation, especially attic insulation. While it is true that other factors need be considered, such as which heating and cooling equipment is installed in your household, if your insulation fails to keep the air inside then you are likely to waste a great deal of energy. If you happen to notice your energy bills skyrocketing as the season gets colder, consider these following tips.
The Importance of Insulation
The amount and quality of the insulation within your home is directly related to how well heated air will stay within the walls. During the winter, insulation will impede the movement of heat to the outside of the house. This keeps heat within, and reduces the amount of work your heating system needs to do to regulate temperature. A similar benefit is gained during the summer months, whereas your cold air is better retained instead of heated air.
Determine What You Have
The first step to improving your attic is to assess how much insulation your home already has. To achieve this, simply measure the thickness and ask a professional to determine your the efficiency rating of your insulation. After that, all you need is simple math.
If your insulation is white, pink or yellow and made from fiberglass, the efficiency value is 2.5. Loose-fill insulation that is grayish in color is made from rock wool or cellulose, and generally has an efficiency rating of 2.8 and 3.7. Multiply that number by the depth of the insulation in inches. If you need to find the value of granule insulation, multiply its depth by its 2.7.
A simple way to tell if you need better attic insulation is if the measurement is less than 11 inches for fiberglass or rock wool, or less than 8 inches for cellulose. Also, if your efficiency rating happens to be below 30, you likely need to add more to get results.
What Type to Use
The best thing about determining your attic installation improvement method is that there are several varieties to choose from. Batts and rolls are extremely simple to apply, as all that need be done is a quick unrolling and application to larger spaces. Loose-fill insulation is also exceptionally efficient and can be blown into attic spaces that are hard to reach or have an unusual shape, as this type of insulation will easily adhere to the area.
