Argon gas is a common method for insulating windows. These windows can have problems with argon gas leakage.
Argon gas-filled windows can leak. Argon gas has no color and no odor. These qualities make it difficult for people to detect. An inability to detect the gas could lead to a situation where the gas leaks without any realization. Argon leakage can be the result of a faulty window seal. Even the smallest gap in the seal will release the argon gas.
Argon gas-filled windows are manufactured using either a one-hole or two-hole gas insertion method. Each of the methods affects the gas seal differently. The one-hole method has only one point of entry for the gas. The one-hole method has only one location where the seal can become faulty. The two-hole method has two points of entry for the gas and two locations where the seal can become faulty. The two-hole method is more likely to leak argon gas because it has twice the likelihood possibilities for faulty seals.
The spacer inside the window can also affect gas leakage. A spacer is positioned inside the window to separate the glass panes. There are two types of spacers. One type is constructed with metal and the other is made from non-metal materials. The metal spacers have a rubber compound seal. These spacers conduct heat and sound and eventually allow the gas to leak. Spacers made from non-metallic materials produce a better seal which will not allow the argon to leak.
