Not only is this a good reflector to your eye of visible light, it is a good reflector of heat.Aluminum is resistant to heat, so it stops heat from the sun. People usually cover the inside of the window with foil using tapes. Since there’s no direct sunlight coming in, the temperature inside the house stays lower than outside.
