![]() ![]() ![]() Window Low-E Coating, glass thickness, and insulating gas are only a couple of the many options we have available for upgrades. Replacement windows are a large investment so choosing the right upgrades to save you money in the future is important. Krypton is the most insulating and does not dissipate through the glass. Argon is used to help insulate but dissipates through glass over time. The introduction of insulating gases into these air spaces creates a better insulating median. Increasing the amount of air space between the pieces of glass makes the insulated glass thickness more energy efficient. They are also much more energy-efficient than single or double glazed windows. Triple-glazed windows are generally 1 inch thick and made of three sheets of glass. The overall measurement, from outside surface to outside surface, is ½-inch - the typical width for double-glazed windows. It means that you’ve got two sheets of glass that are each ⅛-inch think, with ¼-inch of air space between them. When someone refers to ½-inch insulated glass units, it doesn’t mean that the glass itself is ½-inch thick. The thickness of the glass makes a huge difference. Double-glazed replacement windows – Some ready-made, or stock, replacement windows you’ll find at the lumberyards or large home-supply stores are double-glazed with varying degrees of energy efficiency based on several factors.It is the least energy-efficient option because it leaves your home more susceptible to drafts on cold and windy days. Single-glazed windows replacement windows – This is the cheapest option but not recommended for Wisconsin’s climate.Just like choosing the number of panes of glass, there are also options to choose the number of glazes you want like single-glazed, double-glazed, and triple-glazed. Some options to upgrade your replacement windows include Low-E Coating, Glass Thickness, and Amount of Airspace. Upgrading your windows can help with energy efficiency, noise reduction, UV-ray protection, and durability. If you have shopped for replacement windows in the past, then you know that there are more options than just how many panes of glass you can get.

Fortunately, there are red flags suggesting seal failure and severe gas leakage you can watch out for. It can be difficult to verify when the majority of a gas fill is gone without scientific detectors. How to Determine When a Gas-Filled Window Is No Longer Effective? Gas-filled windows can still be an effective thermal barrier two decades after their original installation even if they experience 1% leakage per year. Incremental gas leakage does not make ENERGY STAR-approved replacement windows a waste of money, though. According to some estimations, as much as 1% of gas fill leaks out of the unit per year. It is not uncommon for an insulated filled window to lose its gas over time. Some window replacement experts, including Renewal by Andersen of Greater Philadelphia, mix different gas fills to create a healthier balance between performance and price. The industry considers it more thermally efficient per dollar spent the insulating quality of krypton is just marginally better than argon, but it is far more expensive to produce. Though krypton is the superior insulator, argon is more popular because it’s more affordable. Many gases have used for this purpose, but argon and krypton have proven to the best. To shed further light on the gas fills found in today’s replacement windows, Renewal by Andersen® of Greater Philadelphia answers common questions about them below.
