Did you even know there is gas between the panes of your windows? That’s OK, not many people do. Nevertheless, it’s there, and for a good reason. The most common gas in place between double or triple glazed window panes is argon, which is an odorless, colorless, gas that’s denser than the surrounding atmosphere. It’s better than air between panes because it’s got better thermal efficiency.
Argon, an inert, nontoxic gas, is actually six-times denser than air. That makes it an amazing insulator. Many modern windows offer options of gas fill. This involves inert gases being factory-sealed between panes (typically, krypton, argon or a combination of the two). These gases also happen to be poor thermal conductors, slowing down the passage of heat through the window, according to Home Advisor.
This is a good thing: you can keep more cool air inside during the summer and warm air in during winter, saving you on energy costs. Homes located in hot climates may not need gas fill, in windows, but here in our cold climate of New England, it’s necessary.
Why Gas Filled Windows?
Here are some quick benefits of gas filled double pane windows:
- They help insulate a room by minimizing the transfer of heat through the window.
- They increase your comfort throughout all seasons.
- Argon is not harmful in any way if it leaks.
- They have more thermal insulation efficiency.
- They are used in conjunction with a low-E (low emissivity) glass coating to bring the temperature of the window closer to room temperature.
- They eliminate air currents and drafts that can occur when extreme temperatures collide.
Should You Get Gas Filled Windows?
It’s recommended, yes. First off, you may be concerned about cost. Yes, injecting argon into double-pane windows represents a higher initial cost, because gas filled double pane windows are more expensive than cheaper, single-pane windows. But, keep in mind you will get that investment back and more over the long term because you’ll have lower energy bills. Plus, it just makes sense. Stricter energy codes have been put into place recently, meaning higher efficiency standards are the name of game with any new window installation.
If you are thinking about window replacement, ask your professional window installer about argon gas-filled windows to make sure you’re being as energy and cost conscious as you can possibly be.
