Attic Insulation

EcoFoil keeps your attic cool by reflecting heat.

Reflective Attic Insulation

Use radiant barrier for attic insulation in multiple climates. In warm weather, up to 93% of downward heat gain in a home is from radiant heat that penetrates your attic and seeps downward into your home, making your air conditioner run longer to keep your home cool. Likewise, in cold weather, 50-75% of your home or building's heat loss is due to radiant heat up flow as the warmed air inside rushes out of your living space and into the cool air of the attic and outdoors. Fiberglass and cellulose insulation only slow down radiant heat gain or loss instead of stop it. Only EcoFoil.com reflective attic insulation blocks and redirects the heat. Radiant barrier attic insulation stops up to 97% of radiant heat transfer. (Read more about the science of heat transfer).

How does reflective attic insulation stop heat flow?

Model of an attic with radiant barrier insulation installed
The nearly indestructible metalized polyethelyne attic foil insulation from Eco Foil.com is made with 99% pure aluminum. The aluminum in the attic insulation foil works to reflect radiant heat away and back toward the source. Pairing high quality attic radiant barrier insulation with traditional fiberglass or cellulose insulation is the best attic insulation combination to maximize the energy efficiency of your attic space. Reflective attic insulation can also improve the performance for an attic-based HVAC system. For maximum impact from installing attic foil insulation, attic retrofits are the way to go.

Attic insulation - "Under Rafter" method

EcoFoil insulation installed under attic rafters

In warm summer months attic temperatures can reach as high as 140° Fahrenheit. The heat from your attic tries to invade your cooled living space, making your air conditioner work harder to keep your house at the desired temperature. Radiant barrier attic insulation installed under the rafters in your attic reflects up to 97% of the sun's radiant heat away from your attic. This method of installing attic insulation keeps your attic temperature lower, requiring less effort from your air conditioner. This attic insulation installation takes a few hours and in hot months you should see an immediate change on your energy bill. Some of the most common cities using reflective attic insulation are Atlanta, Georgia, Houston, Austin and San Antonio, Texas, Florida, and Phoenix, Arizona.

Attic insulation - "Over Joist" method

During cold winter months, 50-75% of your home or building's heat can be lost through your attic area due to radiant heat transfer. Fiberglass and cellulose blow-in insulation in attics only slow down heat transfer and do nothing against radiant heat gain or loss. Fiberglass and cellulose insulations absorb and retain heat, but will eventually transfer the heat to cooler air outside the attic roof insulation. Attic radiant barrier reflects up to 97% of radiant heat back toward the living space, keeping your home warmer and saving you on heating costs. Installing radiant barrier attic insulation is clean, quick, and easy with our EcoFoil Perforated Radiant Barrier product. Just roll the reflective attic foil insulation across the attic floor right over top of any existing insulation and and don't place anything directly on top of it (a minimum 3/4 inch air space is required to reflect heat.) This combination is the best insulation for attic spaces that aren't used for storage to minimize heat transfer.
