Is a Radiant Barrier Worth It?

Find out whether it's worth the money to install a radiant barrier in your attic. The answer is that there are other things you can do that would be more effective in terms of energy efficiency. For example, most homes don't have enough insulation to start with. Installing 19 inches of batt insulation or 22 of blown-in is the single most cost-effective way to reduce your heating and cooling costs. If your house doesn't have continuous ridge and soffit vents, that is also a very cost-effective improvement.
