Radiant Barrier for the Attic
Are you hoping to make your home more energy efficient? Do you feel like your cooling costs in the summer are way out of proportion to your home?
A great way to increase the energy efficiency of your home is to install a radiant barrier. Radiant barriers are thin sheets of aluminum installed over your attic’s insulation. Radiant barriers are reflective and keep out the heat in the summer and maintain the warm air when it’s cold outside. Start reducing your energy bills today!
How Do Radiant Barriers Work?
When the sun is pounding on your roof during the warmer months, it generates heat, making the roof very hot. This heat then travels through roofing materials and into the attic. When your attic is hot, it can then travel down into your home, making your cooling system work overtime.
By installing a radiant barrier in your attic, you can reduce radiant heat transfer from the roof to your attic by absorbing that heat. Radiant barriers lower heat transfer rates and keep the attic space cooler, lowering cooling costs by up to 17%.
The highly reflective material of a radiant barrier is usually made of aluminum foil, which can be applied to a number of different materials, including craft paper, plastic films, cardboard, strand board, and air infiltration barriers.
You may also want to combine your radiant barriers with other types of insulation materials to further increase your home’s energy efficiency.
Installing Radiant Barriers in Your Attic
Radiant barriers require specific installation techniques in order to be properly effective.
If you are uncertain about how to install radiant barriers, you should contact the pros at Attic Projects for help.
- The reflective side must always face upwards, so the radiant barrier doesn’t reflect heat from the attic.
- Next, installation should be done early in the morning or during colder seasons, when the weather is cooler.
- Finally, you will need an assistant or a professional installer, as radiant barrier installation involves holding items in place.
If you choose to install a radiant barrier on your own, read the manufacturer’s instructions carefully and ensure you are following all building and fire codes. Improperly installed radiant barriers will not reflect heat and will not cut your cooling costs.
For every update in your home, it’s absolutely critical to follow safety precautions.
When installing radiant barriers, you should remember to keep them away from electrical wires and avoid covering any lighting or vents. Radiant barriers conduct lots of heat and electricity and can be a fire hazard.
You should also wear protective clothing and shoes, and be careful to avoid falling through the floor or walking on nails. If you’re not familiar with the attic, we recommend seeking the help of attic professionals.
Radiant Barrier Installation Methods
There are two methods for installing radiant barriers - on top of the attic floor and on the underside of the roof.
On-Top of Floors
If you don’t use your attic for living or storage, you could install radiant barriers on top of the floor. Just be sure to never walk on them as you could miss a floor joist and put your foot through the ceiling below.
A radiant barrier on the floor is more susceptible to wet, mold and pests. Also, because radiant barriers on the floor are exposed to dust, they could potentially decrease energy efficiency. You also may need to remove and replace radiant barriers in just a few years if they are installed on the floor.
Under the Roof
When you install a radiant barrier to the underside of the roof, you are allowing for proper ventilation, ensuring heat is reflected back up before reaching the floor of the attic. You should contact a professional to install a radiant barrier to the underside of the roof. This type of installation is more complicated.
Benefits of Installing Radiant Barriers
- You can potentially reflect up to 97% of solar radiation
- A cooler attic space means less heat flowing to the living areas below
- Reduced attic temps increase attic ductwork efficiency
- Reduction of overall cooling costs
- Ability to create storage in the attic
