Many of today’s thermopane windows are more than just simple insulated glass. There are ever changing methods that window manufacturers use in an effort to make insulated windows more energy efficient. The problem is that not all of them are designed to last as long as one would expect new insulated windows to last, and some are not as effective as manufacturers can make them out to be.
One common method that is available in modern insulated glass windows is filling the windows with Argon or Krypton gas. The problem with this method is that gases can leak out over time. But amount of time this takes is hotly debated, some saying it is almost impossible for the gas to leak out, while others state that the gas could be gone before the window is installed. Since the equipment required to test the level of argon in the window (or if there is any) is very cost prohibitive, few people can tell you if your gas has withstood the test of time. (more…)
