  • Pro/Cons of Gas-Filled Insulating Glass Units

    These gases are denser than air and reduce the amount of heat transfer through the IGU. When 90 percent argon gas-fill is used in a low-e IGU instead of air, the window insulating value can be improved by up to 16 percent. Krypton can improve the insulating value in a low-e IGU by up to 27 percent.
