Why argon filled windows

A mixture of krypton, argon and oxygen gases is sometimes used to reconcile performance and price, and occasionally xenon and nitrogen are used, as well. However, these windows will usually perform adequately even after many years of gradual depressurization. If the breach is significant, however, the window will no longer be an effective thermal barrier and may require replacement. Condensation or fog inside the window unit indicates that the gas fill has escaped and been replaced with moisture-laden air.

Homeowners should clean the window's exterior to be sure that the observed moisture is, in fact, within the window rather than on its surface. The manufacturer or installer should be contacted if the window fails. Leaks can be detected only with special gas-detection equipment. But homeowners should rest assured that leaked argon or krypton poses no health hazards to a home's occupants.

One rare yet shocking consequence of argon leakage is the sudden implosion of the window. Due to molecular differences between argon and the principal components of air, nitrogen and oxygen, argon under pressure to escape a window unit may exit the seal faster than it can be replaced with air. Under this circumstance, the glass will bend inward to accommodate the gradual reduction in pressure within the window.

While the broken glass usually stays within the unit, on at least one occasion, glass has shattered with enough force to send glass shards flying outward. This phenomenon is quite rare, however, especially in newer windows with superior seals. Normally, air is vacuumed sealed in the cavity. This helps for both insulation and reducing noise from outside.

In recent years, some double glazed windows have been made with different inert glasses. Argon is the most popular and widely used. It is perfectly safe using argon gas as a substitute for air in the double glazed window pane. Normal air is mainly nitrogen and oxygen.

However, argon is already present in the air naturally. This new idea of filling the cavity of double glazed windows with argon gas may be slightly higher price wise than traditional air filled double glazed windows. However, when argon glass is used then energy efficiency savings come into play!
