A space suit can reach +310 degrees farenheit in space when an astronaut is exposed directly to the sun and -290 degrees on the opposite side when the earth shields away the sun. But a flexible radiant barrier laminated into the fabric allows the space suit to reflect the searing heat of the sun and retain the body's warmth on the dark side.

Your home is like a space suit. It should keep heat in when the weather is cold and keep it out when the weather is hot. The same radiant barrier technology used in these space suits can produce dramatic results in your attic ... and bring your heating and cooling bills down to earth.
