We at Renewal by Andersen® are often asked about the optional insulating gas fills that we offer with our replacement windows and patio doors. So, today, we share an overview of how insulating gases work and why you should consider them when it’s time to replace your windows.
First, let’s examine how insulated or thermal glass works. Traditional windows are equipped with single-pane glass set into sashes. The problem with traditional windows is the glass itself: it’s naturally conductive, and the window is mostly made of it. Before insulated glass, homeowners protected their homes from the cold using exterior shutters or heavy curtains.
Today’s insulated glass feature two glass panes, separated by an insulated spacer. The airspace between the glass is usually a vacuum. Heat is conducted through molecules; removing them improves insulation between the glass panels. This has proven to be so effective that all Renewal by Andersen replacement windows and patio doors come with High Performance™ Low-E4® glass, which features a double panel glass assembly.
Insulating Gas Fills
While the air space prevents a significant amount of heat from passing through, it’s not perfect. This is for what insulating gas fills are. Inert gases like argon and krypton are heavier and denser than air. It works much like conventional insulation, but in gas form. These odorless, colorless and non-toxic insulating gases are safe and won’t be a problem in case it leaks. As with other types of insulation, these gases also provide insulation against sound, resulting in quieter indoor spaces.
Argon vs. Krypton
Argon and krypton are two of the most common insulating gases offered to homeowners. We at Renewal by Andersen offer a blend of both gases to create the best insulation for our replacement windows. Krypton provides better insulation, but can potentially shoot up the price of each replacement windows. By blending it with argon, you get an insulating gas that offers the best balance between cost and performance. Insulating gas fills incur additional costs, but considering the potential energy savings they offer, they are options that are worth considering when you’re buying new windows.
