Windows are both beautiful and functional. But as a fenestration, they are one of the weakest links in the exterior envelope of your home. Windows often account for the largest amount of energy losses, and they could be costing you hundreds of dollars each year. That is why manufacturers have taken drastic steps to make replacement windows in Escondido, CA more efficient than ever. One of the leading advancements is sealing inert gas between the panes on an insulated glass unit (IGU).
Double and triple glazed windows feature multiple panes of gas with high R-values. They will make a home feel more comfortable, but also save you money on energy expenses. But replacement windows are a sizable investment. You want to be sure you know as much as you can about modern window technologies so you can choose the best products for your home and your budget. So if you are thinking about upgrading your windows, here is some information you should know about the gas fills between window panes.
What are Gas Fills?
During the early stages of development double glazed windows had normal air sealed between the panes. But it was too reactive to temperature changes and retained too much moisture. And as the air expands and contracts it ruins the seals on the windows along with the energy efficiency. Luckily manufacturers found a better way with the noble gasses argon, krypton, and xenon. They are odorless, colorless, and nontoxic. But they have more density than oxygen, which makes them less reactive and reduces heat transfer.
This is the most popular gas fill in replacement windows. It makes up just less than 1% of the earth’s atmosphere, but because it is so readily available it also makes it affordable. The thermal resistance is 67% better than oxygen and works well in double glazed IGUs.
Per pound, krypton has more density and superior performance than argon. But this gas performs better in thinner profiles, which is why it works well for triple pane windows. That said, it is not as readily available and is more expensive. That is why this noble gas has not overtaken argon gas in popularity.
Trends are moving towards larger windows with larger panes of glass. And with a larger surface area comes a greater risk of an efficiency nightmare. But xenon gas is one way to make these fenestrations more akin to walls and doors. This gas lowers the U-values of windows below those insulated with krypton or argon. But like krypton, xenon gas comes at an even higher price and it will take homeowners much longer to recoup the cost with energy savings.
