There are three reasons why you home may not remain at your desired temperature: conduction, convection, and radiation. Insulation, which is found in most homes, is a way to reduce cool or warm temperature loss. Radiation, however, can be reduced through the best technology on the market -- called radiant barriers.

Radiant barriers are made of a highly reflective material (such as cardboard covered in aluminum foil) that reflects heat from the sun, or reflects heat within the house. In other words, a radiant barrier is a convenient and inexpensive way to help keep your house cool in the summer and toasty and warm in the winter. And, because you’ll be heating or cooling your house more efficiently once you install a radiant barrier, it could reduce your energy bill by 25%!
