Radiant Barrier – Energy-Efficient Attic Insulation
A radiant barrier is a reflective insulation material that reduces radiant heat transfer and helps keep your home cooler. It is a great option for new construction or for those replacing their existing attic insulation.
Radiant barriers were first patented by two German businessmen, Schmidt and Dykerhoff in 1925. They are now a standard feature in many homes. Visit https://www.ultimateradiantbarrier.com/ to learn more.
Radiant barriers reflect 97% of radiant heat, which can help reduce the amount of energy needed to keep homes and buildings comfortable. They can be installed in attics, garages and an infinite number of commercial applications to improve comfort and save energy.
They also keep the attic cooler and prevent radiant heat from making it through the ceiling to the living space. This makes it easier to maintain a consistent indoor temperature, rather than cycling between too hot and too cold. As a result, less strain is put on HVAC systems, which can prolong their life and further reduce cooling costs.
Unlike traditional insulation, which works by slowing down the transfer of heat through conduction and convection, radiant barriers block thermal radiation from entering a home or building. This can significantly reduce energy costs and increase comfort in warm climates.
There are many different types of radiant barrier, but they all work in the same way. They consist of a highly reflective surface, typically aluminum foil, adhered to a stiffer material for support. This can be cardboard, plastic film, kraft paper or oriented strand board (OSB). They are available in both perforated and non-perforated versions. The perforated version allows for water vapor to pass through, while the non-perforated is not permeable and acts as a air infiltration barrier.
Some radiant barrier companies offer package deals for homeowners that include other energy-saving measures such as air sealing and duct sealing. It’s important to understand what each component will cost before you sign a contract, and shop around to get the best deal.
When installed properly, radiant barriers work well to keep the attic cooler and lower heating and cooling bills. They can be used alone or in conjunction with other traditional types of insulation, such as blown-in attic insulation. Radiant barriers work by reflecting the heat that would otherwise reach insulating materials in the attic floor and the rest of the house. This can reduce energy consumption by 5% to 10%, depending on the climate. Adding radiant barrier can even enable you to downsize your air conditioning system.
Reduced Energy Bills
Radiant barriers are a great way to reduce energy bills by keeping heat outside in the summer and inside during the winter. This helps your HVAC system to conserve energy and save money by not having to run as often or as long to keep the house comfortable. Ultimately, this can add up to big savings on your energy bills over time.
There are several things that can affect how well a radiant barrier works, and it is important to consult with a professional insulation contractor. They can help you choose the right type of insulation and install it properly for maximum benefits. In addition, they can recommend any other energy-saving measures that may be beneficial in your home.
It is also important to note that radiant barriers are only effective in hot climates and when used in conjunction with additional attic insulation. In some cases, they can reduce cooling costs by up to 10 percent. However, this varies by home.
While it is possible to do a DIY installation of a radiant barrier, it is usually best to work with a professional company. This will help you avoid mistakes that can reduce the effectiveness of the product and save you a lot of time and money in the process.
A radiant barrier prevents the movement of heat and will help you cut down on cooling costs in your Phoenix Valley home. It is especially useful for older homes that have outdated and inefficient insulation. The radiant barrier will reflect the heat away from the roof and into the attic space, reducing the need for your air conditioner to work harder to cool the interior of the house.
Radiant barriers are typically made of foil and have a reflective surface that keeps the sun’s heat off of the attic floor and the ceiling. The heat is instead reflected back into the attic where it can be more effectively dissipated with existing insulation or air vents. In the end, this will lower the amount of energy you use to cool your home and make a significant difference on your monthly electricity bills.
Increased Resale Value
Radiant barriers are a great addition to any energy conservation strategy and can be easily installed in the ventilated attics of most homes. However, they are only effective if they have an air space behind them in order to stop radiant heat transfer from the roof to the conditioned living spaces below. A properly installed radiant barrier will increase a home’s resale value and should be considered by any homeowner interested in improving the efficiency of their home.
There are many different types of radiant barriers on the market. The type chosen should depend on the needs of the particular building. For example, perforated radiant barriers have small holes in them that allow moisture vapor to pass through the material. However, they also have a lower reflective coating than solid radiant barriers. Solid radiant barriers like RadiantGUARD Xtreme are highly durable, containing a middle layer of woven polyethylene that is sandwiched between the two layers of metalized film. The woven polyethylene adds strength to the product so that it cannot be ripped or torn. This material has a reflectivity of 95-97% and an emissivity of 3-5%.
The best radiant barrier is not necessarily the most expensive. Instead, homeowners should focus on finding a company that offers competitive pricing for both the materials and installation. Some companies offer “package deals” that include the installation of a radiant barrier along with other energy saving features. In these cases, it is a good idea to get estimates for the individual items so that you can compare prices and find the best deal.
The cost of installing a radiant barrier can be partially offset by federal and state rebates and tax incentives for home improvements. Check the Energy Star rebate finder and the Database of State Incentives for Renewables & Efficiency to see what discounts are available in your area. In addition, you can save even more by having your radiant barrier installed as part of a larger home insulation project. For example, adding blown-in cellulose insulation to your home could qualify you for a large discount on the total installation cost of the radiant barrier.
Radiant barriers are easy to install, especially in new homes. They can be draped over existing insulation or stapled directly to the underside of the attic roof rafters, and they are often applied by builders in warm climates to cut down on the time that roofers spend up on the rafters.
A radiant barrier reduces heat transfer by reflecting thermal radiation back into the room, but it doesn’t stop airflow like traditional insulation. Therefore, it is important to properly ventilate your attic space before installing a radiant barrier. This will help prevent the build-up of heat and moisture that can diminish its effectiveness.
While the installation of a radiant barrier is fairly simple, homeowners should use caution when handling it. Be sure to wear protective clothing, gloves, eye protection and breathing protection. Be especially cautious when working around ductwork and other potential hazards in the attic, such as electrical wiring. Additionally, when stapling the foil-faced insulation boards into place, it’s crucial to avoid compressing or flattening any existing insulation in the attic. This can lower the R-value of the existing insulation, reducing your energy efficiency.
It’s also a good idea to make a note of the location of any vents, chimneys or electrical wires in your attic before you install the insulation. These are all areas where air leaks are most likely to occur, so sealing them up prior to installing the barrier is essential. This will ensure that the radiant barrier is properly installed and provides you with maximum benefits.
Another great tip for homeowners who are laying the radiant barrier on their attic floor is to highlight any areas of the attic that they commonly walk across to access equipment and storage spaces with a brightly colored tape. This will allow you and any contractors or repairmen who access your attic in the future to clearly see where it is safe to walk without damaging the insulation or creating a safety hazard.
Finally, it’s important to remember that radiant barriers are more effective in warm climates where cooling costs can be higher. They can reflect much of the radiant heat from the sun that would otherwise be absorbed into the attic space, lowering the attic temperature and helping your AC to work less hard to keep your home comfortable.
