Radiant Barrier is an essential part of an efficient home.
Radiant Barrier blocks radiant heat, one of the three ways that heat enters your home from the outside. Combined with Attic Insulation, Attic Ventilation, and energy-efficient Windows, Radiant Barrier can greatly reduce your home's heat load and reduce the amount of work your air conditioning system has to do.

What Radiant Heat Is
Naturally, heat travels from warm objects to cooler objects until all objects are the same temperature. The rate of heat flow increases the greater the temperature difference between the two objects.
Radiation is one way that warm objects transfer heat to cooler objects around it. The Sun is the best example: it is extremely hot and transfers that heat to the Earth by radiation (sunlight). When the area you live in is covered in clouds, the temperature is not as hot, because the clouds reflect much of that energy back into space.

Objects that are not as hot as the sun may not glow, but they are still emitting radiant heat. This heat is just being emitted at wavelengths that your eye cannot see.
The roof of your house absorbs sunlight all day, heating up to around 130°F during the summer. The hot roof then emits radiant heat in all directions... including into your attic!

Radiant Barrier greatly reduces heat flow into your home due to radiation.
The sun's heat enters your home in three primary ways:
- Convection (when you open doors or windows and let hot air in),
- Conduction (the outer walls and attic deck warm up and conduct the heat to the inner walls and ceiling),
- and Radiation (the hot roof produces radiant heat that heats everything in the attic).
Reducing these heat sources improves the efficiency and performance of your air conditioning system. The effects of Conduction are reduced by adding Attic Insulation, and the effects of Radiation are reduced by adding Radiant Barrier.

Radiant barrier consists of a material (usually reflective) that is applied to the underside of the roof deck to prevent radiant heat from entering the attic. Instead, the radiant heat is reflected back to the roof deck and out to the outdoors.
The result is that the attic deck and all of the objects in the attic (including any air conditioning equipment in the attic) stay cooler because they are not absorbing all of that radiant heat.

Foil Radiant Barrier
Foil Radiant Barrier consists of sheets of metal foil that are stapled to the rafters under the roof deck. Foil Radiant Barrier blocks around 97% of radiant emission into the attic. Foil Radiant Barrier has a low material cost, but the installation can be manpower-intensive.
Bubble Foil Radiant Barrier
Bubble Foil Radiant Barrier is similar to Foil Radiant Barrier, only it has a layer of plastic bubbles between two layers of metallic foil. The Bubble Foil Radiant Barrier also blocks about 97% of radiant emission. In addition, the air pocket provided by the bubble layer provides a small amount of conductive insulation (~R-2). Bubble Foil is more expensive than regular Foil, but it is more durable and easier to install.

Spray-On Radiant Barrier
Distinctly different from Foil-type Radiant Barriers, Spray-On Radiant Barrier is a type of paint that is applied directly to the underside of the roof deck using a paint sprayer. Spray-On Radiant Barrier has reduced emission blocking performance compared to Foil Radiant Barriers (depending on the source, ~80%), but is easier to apply for larger homes.
