Problems with Argon Gas Leakage in Double Paned Windows

Argon gas is a common method for insulating windows. These windows can have problems with argon gas leakage.

Faulty Seals

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 method affects the gas seal differently. The one hole method has only one point of entry for the gas. The one hold 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 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.
