Energy-Efficient Windows: Gas Fills and How They Work

Heat gain and loss due to poor windows accounts for up to half of your home’s cooling and heating needs. It’s precisely for that reason that you need to pay close attention to the window products you choose to adorn your home with.

Thankfully, windows these days such as Renewal by Andersen® replacement window products have high energy efficiency ratings. The fact that they feature gas fills contributes to this. Here’s a look at how gas fills work

What Exactly Are Gas Fills?

To improve thermal efficiency in windows, manufacturers pump these special gases inside insulated glass units. Because they are slow moving gases, they allow less convection compared to ordinary air. As a result, you get a significant reduction in the transfer of heat across your window.

The most common gases used by manufacturers used for windows are argon and krypton. Both of them are inert, clear, and odorless. What’s best about them is that they are excellent in terms of heat conductivity and are very much affordable. This makes them the ideal gas fill for windows.

How Do I Know if Windows Have Gas Fills?

Homeowners and window suppliers alike can tell if custom windows have gas fills simply by checking the exact specifications of the window tag. Aside from this, you will also notice the presence of two small holes along the window’s spacer. These are the spots where gas entered as well as exited the unit.

Don’t settle for replacement windows that don’t offer much in terms of energy efficiency. Make it a point to look for products that have a good balance of aesthetic appeal, functionality, and sheer energy efficiency. Investing in such windows will give you many benefits in the end.
