Protect your home from radiant heat transfer with EcoFoil radiant barrier
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 conditioning run longer to keep the air 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 do not stop radiant heat gain or loss. Only attic radiant barrier such as EcoFoil® reflective insulation stops 97% of radiant heat transfer.

What makes EcoFoil the right product for your attic insulation?
- Ecofoil is durable and safe - our radiant barrier is the first to pass the ASTM E84-2009 test as a Class 1/Class A flame retardent radiant barrier. People consider EcoFoil the best attic insulation as it is virtually indestructible and impossible to tear, yet does not require special clothing or breathing equipment to install and there is no debris left over when you insulate attic ceiling spaces.
- Radiant barrier is an economical addition to your energy savings strategy - it is easy to install and can be an afternoon DIY project for 1-2 people. You just cut a length with standard scissors, roll the insulation over the face of your attic rafters and staple into place with a manual or pneumatic staple gun.
- EcoFoil is the most reflective radiant barrier of its kind reflecting 97% of radiant heat when installed with adequate air space on one or both surfaces. What is the best attic insulation? EcoFoil.
- Radiant barrier is waterproof and non-absorbent; EcoFoil does not promote growth of mold or fungi (ASTM C1338-08) and pinpoint perforations prevent condensation build up in attic spaces.
Radiant barrier attic insulation - "Under Rafter" method
In warm summer months attic temperatures can reach as high as 140° Farenheit. 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. Home 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 radiant attic barrier will keep your attic temperature lower, requiring less energy consumption from your air conditioner. This attic insulation installation will only take a few hours and in hot months you should see an immediate change on your energy bill.

Radiant barrier 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 can 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. 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 house attic insulation is clean, quick, and easy with our EcoFoil Perforated Radiant Barrier product. Just roll the foil attic 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" 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. Download our installation guide for installing radiant barrier over an attic floor.
