Open-celled spray-in foam insulation is by far superior to a traditional radiant barrier which is a foil-like thing that you can either tack to the rafters or lay on the floor of your attic. Open-cell foam is also more expensive, but in my opinion an excellent investment.
Full Answer
Is spray foam insulation a radiant barrier?
Spray foam insulation doesn't protect attic spaces from radiant heat, but does protect them from convection and conduction.

Which is better spray foam or insulation?
When it comes to which is best in the spray foam insulation vs. fiberglass debate, spray foam wins, hands down. If you're a DIY-er, you may be used to installing fiberglass insulation. But if you're looking for something that will last a lifetime, let a professional install spray foam.
Is a radiant barrier worth the money?
Some studies show that radiant barriers can reduce cooling costs 5% to 10% when used in a warm, sunny climate. The reduced heat gain may even allow for a smaller air conditioning system. In cool climates, however, it's usually more cost-effective to install more thermal insulation than to add a radiant barrier.
Does radiant barrier affect WiFi?

Do you need insulation with radiant barrier?
Radiant barriers reflect radiant heat. Then, the heat transfer method switches from radiant heat to conductive heat to move through the attic insulation and into your home. This is why you need both types of insulation.
What is the average cost to install a radiant barrier?
The cost to install radiant barrier insulation runs from $740 to $2,840 or $1,700 on average. Materials for this project run as low as $0.10 per square foot, up to $0.95. Professional installers typically charge $30 to $80 per hour for this job. Radiant barrier is best suited to attics.
Is Radiant Barrier OSB worth it?
Is Radiant Barrier OSB Worth It? If you use OSB radiant barrier sheathing, you can reflect up to ninety-seven percent of solar radiation. This amount of solar heat reduction can reduce your attic's heat by up to thirty degrees Fahrenheit. Radiant barrier roof sheathing can also improve comfort in other areas.
Is radiant barrier worth it in Texas?
The average temperature in Texas during the summer is between 86 and 98 degrees Fahrenheit. When combined with low rainfall levels and low humidity, 90-degree temperatures can feel unbearable. As part of a whole-attic system, radiant barriers can improve the comfort of your home.
Is radiant barrier the same as insulation?
A radiant barrier aims to reduce summer heat gain and lower a home's cooling costs, but not in the same way thermal insulation does. Unlike fiberglass, cellulose and other traditional thermal insulation, radiant barrier isn't installed on the attic floor — it's installed in the attic ceiling just below the roof.

Spray foam insulation is also a great option for homes that are smaller, or for homes with attic spaces that are difficult to insulate with alternative insulation.
Do I need a radiant barrier with spray foam?
Spray foam insulation should never be installed in direct contact with radiant barriers. This will negate the function of the radiant barrier because an air gap is required for the radiant barrier to work properly in reducing radiant heat.
Does spray foam stop radiant heat?
By combining radiant barrier foil with spray foam insulation you create two defenses for reducing heat flow into your home.
Can you use spray foam and radiant barrier?

Which attic insulation is best?
Spray foam offers the best attic insulation performance available. Choose from two types: closed-cell and open-cell, aka 2-pound and ½-pound, respectively. They sport insulation values of approximately R-6.5 and R-3.6 per inch, respectively.
What is foam insulation?
Foam insulation is designed to slow down the conduction and convection of heat and is typically installed against the interior or exterior of plywood sheathing. Because radiant barrier works differently, by preventing the radiation of heat, it is ideally installed in an area with an airspace such as an attic or metal roof. Since these two types of insulation work differently, foam insulation often comes with an R-Value measurement, while radiant barrier does not. Radiant barrier’s effectiveness is measured by thermal emissivity, which is around .05 (at least 95% of radiant heat reflected).
Can a radiant barrier be combined with insulation?
Radiant barrier can be easily combined with other insulation.
Does spray foam insulation block noise?
