Reflective Insulation has been around for many years. Due to the rising cost of energy it is playing a more important role. This type of insulation resists all three types of heat transfer - Conduction, Convection and, most importantly, Radiant Energy.
Heating and cooling ("space condition") account for 50 to 70% of the energy used in the average American home. About 20% goes for heating water. On the other hand, lighting and appliances and everything else account for only 10 to 30% of the energy used in most residences.
Much of the existing housing in the United States is not insulated to their best level. Older homes are likely to use even more energy than newer homes. Adding Reflective Insulation may save enough money in reduced utility bills to pay for itself with a few years.
The amount of energy you conserve will depend on several factors:
Inadequate insulation and air leakage are leading causes of energy waste in most homes. It can also make your house more comfortable by helping maintain a uniform temperature throughout the house.
Walls, ceilings and floors will be warmer in the winter and cooler in the summer. Reflective Insulation can also act as a sound barrier, keeping noise levels down.
