Another important part of your roof is what lies beneath it, namely the roof deck and attic that serve as the upper most part of your home. The attic is usually the first place where we can begin to see water damage as a result of leaking roofs, and can also be a spot where your home is losing heating or cooling due to poor insulation. All of these problems can cost you thousands in repairs and lost energy, and will eventually add up over the lifetime of the roof. It is important when making any updates or repairs to your roof that your contractor is looking for these issues and suggesting ways to fix them when appropriate.
How Much Attic Insulation is Necessary?
The Department of Energy recommends a minimum of R-49 for the Toledo area climate zone. R-Value is a measure of insulation's ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation. To achieve the level of R-49, you need approximately 18-20 total inches of insulation. The insulation's resistance actually comes from the millions and millions of tiny air pockets that are created during the manufacturing of the fiberglass fibers. The deeper the insulation, the greater the number of air pockets and the greater the resistance. The higher the R-value rating on the insulation the better it will be because this means that it has a higher thermal value.
How Important is Attic Insulation?
Attic insulation is more important than the insulation in any other part of your home. This is because heat rises at all times of the year. Frogtown Roofing knows the value of making sure you have adequate insulation in your attic and we recommend its use to our customers. The insulation you place in your attic can contribute greatly to making your home as energy efficient as possible. It also is necessary to complete the total roofing system. Eliminating premature deterioration of your roof and the potential of moisture build up in your attic. Moisture potentially could cause many issues for your family and your home.
Purpose of Attic Insulation
Since heat rises you will lose the majority of heat from your home through the attic if you do not have it properly insulated. This lack of insulation in older two-story homes is the main reason that the upstairs portion of the house is cold in winter and stifling hot in summer. In order to better understand the need for insulating the attic you should be aware of the properties of heat that necessitate this.
Heat in the attic in winter. Your attic should be cold in winter because the insulation that you have on the floor prevents the heat from penetrating through the ceiling. This will help you maintain utility bills within your budget because you are not losing any heat that is really wasted in the attic.
Heat in the attic in summer. To accomplish a properly insulated attic it is required to insulate the attic you do not insulate the roof. Therefore, the heat from the sun penetrates the roof during the summer and it can become unbearably hot. The insulation on the floor prevents this heat from coming down into the main part of the house that you are trying to cool by having the windows open or the air-conditioning running.
R-Value of Attic Insulation
When customers ask us about how much insulation they need to have in the attic, they can be sure of receiving an honest answer from Sunshine Contracting. There should be no less than 12 inches of insulation in this highest part of your house. The higher the R-value rating on the insulation the better it will be because this means that it has a higher thermal value.
Why is Air Sealing Important in an Attic?
According to both the U.S. Department of Energy and the Environmental Protection Agency, "air sealing is one of the most critical features of an energy efficient home." The ceiling between the attic and the living space should serve as an air barrier, prohibiting the flow of air between your attic and the interior of the home. Any openings in this barrier help contribute to drafts, moisture transfer, dust, airborne pollutants, all of which can impact the structure of your home and the air quality within it.
Make sure your attic is properly sealed, ventilated and insulated to keep your energy costs low, and to help keep your roof and attic free from mold and water damage.
