Stop up to 93% of heat transfer with EcoFoil radiant barrier
In warm weather, up to 93% of heat gain is from radiant heat. Likewise, in cold weather, up to 75% of your home or building's heat loss is radiant heat. Fiberglass and cellulose insulation do not stop radiant heat gain loss. Only a radiant barrier such as EcoFoil® reflective insulation stops 97% of radiant heat transfer.

Radiant barrier attic insulation - "Under Rafter" method

In warm summer months attic temperatures can reach as high as 140° Farenheit! The heat in your attic tries to invade your living space making your air conditioner work harder to keep your house cool. Radiant barrier installed under the rafters in your attic reflects up to 97% of the sun's radiant heat away from your attic. This method will keep your attic temperature lower, requiring less energy from your air conditioner.
Radiant barrier attic insulation - "Over Joist" method

During cold winter months, up to 75% of your home or building's heat can be lost through your attic area. Fiberglass and cellulose blow-in insulation can only slow down heat transfer and do nothing against radiant heat gain or loss. Fiberglass and cellulose insulations absorb and retain heat, but eventually transfer the heat to cooler air. 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 attic insulation is clean, quick, and easy with our EcoFoil Perforated Radiant Barrier product. Just roll it out across your attic floor right over top of any existing insulation.
