Reflective insulation, also referred to as radiant barrier insulation and foil insulation, is installed in many homes, primarily in attics. As its name suggests, reflective insulation helps your home reflect, rather than absorb, energy from the sun. Without radiant heat being absorbed, your attic and the rest of your home stay much more comfortable!

Benefits of Reflective Insulation

Insulating your attic is one of the easiest ways to maximize your home’s energy efficiency and start saving money. In addition to this, reflective insulation installation in your attic can:

  • Make your home more comfortable year round
  • Lower the attic’s temperature by as much as 30 degrees
  • Increase the efficiency of your AC, resulting in AC savings of up to 12%

Reflective insulation is most effective in hotter climates, particularly if an attic has cooling air ducts. It’s also recommended to install foil insulation if:

  • Your attic has little or no insulation (or the insulation has aged)
  • Your home has little or no shade from trees
  • The rooms on the second floor feel hot
  • You have an asphalt shingle roof, which can get extremely hot

Reflective Insulation Installation

Reflective insulation, made of aluminum foil, is one of the most popular types of radiant barrier and its effectiveness depends primarily on installation. If installed improperly, it doesn’t do what it’s intended to do – reflect radiant heat and keep your home more energy efficient! For instance, it’s best to let the material”droop” to leave space between the barrier and the bottom of the roof (creating an air channel, for more effective ventilation). Many homeowners don’t know these kinds of specifics, but professional insulation companies like OJ Insulation do! We can expertly install reflective insulation so it maximizes your energy savings and keeps your home more comfortable, year in and year out.
