Change starts with you. Use less heat and air-conditioning. Adding insulation to your walls and attic, and installing weather stripping or caulking around doors and windows can lower your heating costs more than 25 percent, by reducing the amount of energy you need to heat and cool your home.
Radiant barrier is an optimal attic insulation option. Radiant barriers are radiant heat reflectors that helps reduce the amount of heat that is transferred from the roof to the attic. By reflecting the heat from the roof the attic remains cooler which limits the heat being redistributed to the rest of your home.
