Why Your Windows Are Filled With Argon Gas

There is more to good quality windows than just frames and glass panes. A window’s efficiency is affected by the type of seal, coating and gas fill used when making it. Not all homeowners are aware that their windows may actually be filled with gas.

Window Gas Fills

Windows manufactured before the 1950s weren’t filled with gas yet. Following decades of testing various gases, argon emerged as the most cost-effective choice for window manufacturers. Gas fills help insulate windows better.

Gas Fill Drawbacks

When improperly installed, your windows can leak gas. You can end up with foggy windows when condensation develops in the space between your panes. The same can happen if your windows aren’t sealed right, too. Avoiding these is why it has become so important to have your window design and window installation overseen only by a certified top window company.
