eShield™-Radiant Barrier is insulation for Hawaii's climate. This state-of-the-art attic insulation reflects 93 percent of all radiant heat transfer, or heat from the sun, cooling your attic by as much as 40 degrees. It's like having a shade over your home!
During the day, the Sun warms our homes through Solar Radiation. This is the process by which the Sun’s light is transferred into heat. Fortunately, preventing attic and home heat can be as simple as using eShield® reflective insulation to slow the entry of heat into the attic and home.
How eShield Reflective Insulation Works
In the same way that the air in a closed car left in direct sunlight will be much hotter than the surrounding air, the enclosed space of an attic when the roof is struck by direct sunlight will also be much hotter than the air around it.
As air is warmed, it will also expand. Without adequate venting for expanding air to escape, this hot air will tend to push down into the home making the house even hotter. As an example, in many two story homes the upstairs is typically hotter than the ground floor.
eShield®, made with two layers of reflective foil and an insulating fiberglass core, is superior reflective insulation for new-home construction and retrofitting an existing home. In hot climates eShield® is much more effective at preventing heat gain than thermal insulation.
When properly installed and vented eShield® is:
Note: SolarGuard Reflective Insulation is two layers of radiant barrier plus insulation. As of December 2012 Hawaii’s Energy Code was revised to allow for Radiant Barrier in walls of new and existing homes.
This is amazing, my house is so much cooler. I’m trying to tell my neighbors how well this works & that this is the real deal!”

I was at work when it was installed, but when I stepped into the home afterwards I noticed an immediate difference in temperature. Ewa is hot during the day, but the reflective insulation kept the heat out of the home until the air cooled down. When the Whole House Fans were switched on, I had a cool breeze being drawn into the bedrooms from the fairways. My system has worked so well!”

Even without credits, insulation is still a great value and highly effective in cooling most homes. For current credits see Energy Star on Tax Credits.
