new Insulating gas testing

Windows are sealed units called Insulating Glass Units (IGUs). IGUs are filled with dense gasses. Krypton is the best gas, but argon is more widely used. All window IGUs will lose gas. Even windows that "exchange gas for air" can perform well.

  • Insulation | Department of Energy

    Insulation materials run the gamut from bulky fiber materials such as fiberglass, rock and slag wool, cellulose, and natural fibers to rigid foam boards to sleek foils. Bulky materials resist conductive and -- to a lesser degree -- convective heat flow in a building cavity. Rigid foam boards trap air or another gas to resist conductive heat flow.
