Double and triple glazed windows provide better insulation. Metallic coatings are often used as thermal barriers. Warm edge or plastic spacers that come with many modern windows prevent loss of heat from the interior atmosphere. Krypton and argon, two different types of inert gases, are used to create a thermal barrier in the double and triple glazed windows. Glass with reflective surfaces and thin plastic films that prevent the absorption of heat often increase the energy efficiency of your building.
