Radiant Barrier Info Radiant Barrier is an aluminum foil material installed in a building to help reduce the amount of energy used for heating and cooling the building. The radiant barrier helps reduce the amount of heat gained during the summer and heat lost during the winter. A radiant barrier is a cost-effective alternative to constantly changing the thermostat settings during the winter and summer seasons. Adding a radiant barrier in the building will reduce utility bills and provide more comfort for those inside the building. A radiant barrier can be used for commercial, industrial and residential purposes. So whether you are at home or at work, adding a radiant barrier can help you feel more comfortable and provide considerable savings on your energy costs. A radiant barrier is something to consider if you are building a new home or remodeling one. For residential purposes, a radiant barrier installed in the attic can stop 95-97% of the radiant heat that strikes its surface. Other advantages of a radiant barrier are that it is easy to buy and easy to install with no special tools required. Learn more about radiant barrier applications in a residential building.
