Radiant barrier

Radiant barrier is like wearing sunglasses for your house. The sun sends heat to our homes like a big flashlight, and when it hits the roof, it makes the inside of our home hotter. A radiant barrier is a shiny piece of material that reflects the sun's heat like a mirror so it doesn't get inside. It's like wearing a hat on a sunny day to keep the sun's heat off your head. So, when you have a radiant barrier in your attic or on your roof, it helps keep your home cooler because the heat of the sun can't get inside.
