Many homeowners think of sealing doors and windows to make their home more energy efficient but did you know that majority of energy loss is through the attic? Your attic can become very hot during the summer and may even get up to as high as 165 degrees Fahrenheit. This high heat can work its way to the rest of your home that forces your cooling system to work harder and consequently your utility bills will rise. If you are planning a home improvement project, a radiant barrier is a great way of increasing the energy efficiency of your home and saving on your energy bills in the summer as well as in the winter.
Benefits of Radiant Barrier
Radiant barriers prevent the penetration of high heat through the attic in summer months while keeping the hot air from escaping through your attic during winter. According to a report by ConSol, utilizing radian barrier sheeting is one of the best methods of making homes energy efficient considering cost and return on investment.
The U.S. Department of Energy has listed radiant barriers as an effective method of increasing energy efficiency. It is reported that radiant barriers can prevent radiant heat from penetrating the attic as much as 97%. This alone can significantly reduce your cooling cost during the summer months.
An analysis conducted by SGS indicates that radiant barrier also block the heat during winter times from escaping through the attic and therefore reduce utility bills as much as 5% which makes radiant barrier a great energy saving method throughout the year.
Selecting a radiant barrier
While constructing or renovating a house, speak with your builder in regard to installing a radiant barrier. Various types of radiant barriers are sold on the market, however not every one of these radiant barriers are the same. An important point to take note of is how rapidly the radiant barrier recovers from possible moisture.
To be certain that the renovator is utilizing a radiant barrier that is built to prevent moisture problems, it is crucial to comprehend how these products are built. Radiant barriers usually have oriented strand board (OSB) panel with some levels of aluminum attached to the top. Various radiant barrier producers buy foil materials that are pre-perforated. These materials might prevent the panel from berthing and thus does not allow the moisture in the panel to dry.
Therefore, it is paramount to ask the builder or the supplier where the radiant barrier was bought from about the ability of recovering from moisture. Also read the manufacturers guidelines which explain how these products were designed.
In order to reduce attic heating, the contractor could suggest spray-foam insulating material to close off the attic and make room for the HVAC gear. Although this may be a useful technique with the correct quantity of foam applied, it may turn out very expensive
A new report by Oakridge National Laboratory has revealed that radiant barrier roof sheathings bring equal efficiency when compared with roofs that have spray-foam insulating for the attic. However, the spray-foam insulating has significantly higher cost.
Whether constructing or renovating a house, a radiant barrier without a doubt is a great method of attaining energy efficiency. As mentioned above not every single radiant barrier product is the same. Selecting the appropriate radiant barrier material will save you in the long run from various issues and damages related to moisture
