So what is a radiant barrier?
Reflective insulation is a highly reflective material that blocks heat radiation to an object from becoming energized by UV rays and radiating its own heat. They are installed in homes during the summer, usually in the attic, to reduce heat gain and help in minimizing cooling costs as a supplement to attic insulation. Instead of absorbing heat, reflective insulation reflects the heat away from the surface.
According to the Department of Energy, reflective insulation should have a high reflectance of at least 90% and 10% emittance or less.
How does reflective insulation work?
Here’s how they work. Have you ever cooked with an iron skillet? The handle eventually gets hot. That’s because heat flows towards colder areas. In warm weather, if your home’s interior is 68 degrees and it’s 85 degrees outside, heat is attracted to the cooler temperature inside. The sun heats your roof and attic. The hot air travels from your attic into your comfortable home – and heats it up. That’s unless you have a reflective insulation working alongside your attic insulation.
One advantage of reflective insulation over regular insulation is that they don’t get affected by humidity. Reflective insulation will perform consistently no matter how humid the seasonal climate is.
There are different types of radiant barriers. The main component is a reflective material, typically foil insulation. The foil is on one or two sides of the base material (cardboard, paper, plastic film). Some barrier products use reinforced-fiber for more durability.
Reflective insulation consists of thin sheets of reflective materials. In the winter, it works to keep heat in your home by preventing heat loss through your roof. And in the summer, it keeps the heat from entering your attic through the rooftop and making your home hot. We provide it over your attic insulation to make it more energy-efficient. So, you can consider it super roofing insulation that will save you money on your utility bills and also keep your home at a more comfortable and consistent temperature. Radiant barrier foil insulation works alongside existing insulation to enhance the overall performance and contribute to a cooler attic and less hostile environment for your air ducts and other systems in the attic.
That’s simple; you find a local licensed insulation contractor like Envirosmart Solution that provides the services you need, such as installing radiant barriers and install attic insulation, and has excellent reviews.
The radiant barrier creates a cooler attic which helps reduce cooling costs. There are also some comfort improvements. Overall, when installed properly radiant barriers can provide reduced energy costs and cooler attics. The sheathing products are pretty cost effective because they add little additional cost.
A cooler attic space means less heat moving to the cooler space below the attic. The hotter it gets the better radiant barriers work
Radiant barriers need an air space in front of them. If they’re sandwiched between two pieces of insulation or siding, they become conductors and will actively be working against your insulation. Second, a radiant barrier is only effective if it is reflective

If you're noticing poor attic ventilation and moisture problems, your old reflective insulation might be the source and need replacement. That's what happens with improper installation. With excess moisture comes rot and mold, which can lead to problems for the structure of your home and the health of your family.
Sometimes, it isn’t the fault of the reflective insulation (again, also known as radiant barrier). Instead, the roof has poor ventilation. We can come out to your house, do an inspection, and let you know where the excess moisture problem is coming from and give you a solution.
Here’s a quick check you can do yourself to see if the barrier is applied where it’s supposed to be:
How Does Reflective Insulation Work?
Reflective insulation is designed to BLOCK (reflect) radiant heat and radiant energy unlike traditional insulations that are designed to slow it down by absorbing radiant heat. A radiant barrier can also REDUCE heat transfer caused by convection by blocking convective air flow.

For effectiveness, a radiant barrier requires correct installation by professionals like the team at Envirosmart Solution. Installation isn’t a DIY type job and can be ineffective and dangerous if you don’t know what you’re doing.
For example, the material does conduct electricity, so you have to be careful you don’t get shocked or worse. If you’re building a new home, call us during the construction process. We’re happy to do your roof rafters insulation installation. For existing homes, we never install a barrier over the top of the existing insulation on your attic floor because it can trap moisture, which is already a problem in our area.
The most effective installation method is connecting the radiant barrier to the underneath side of the roof. That way, heat reflects and doesn’t enter the attic. Your attic will stay cooler and have proper ventilation.
