What Makes a Window Energy Efficient?
LowE
You have probably heard the term LowE, which stands for low emissivity. It’s a coating applied to the inner part of the exterior window pane to reflect light and heat back out. It keeps whatever the climate is inside the house inside and the climate outside, outside.
Argon Gas
Argon gas is another way of insulating the window sashes. Argon gas is heavier than air, which is inserted after air is vacuumed out between the panes. If you want to meet Energy Star requirements in the southern region, you really need to have the LowE coding on the glass and the Argon gas.
Foam Filled Frames
Another option that we have to make a window more insulated is foam filled frames – in the master frame of the window and also the sash frames. This is really going to be more beneficial for colder climates. It’s hot here in Kentucky, so it’s not a must have in terms of energy efficiency, but always an additional option if you want more insulation.
Triple Pane Windows
Triple pane is another option. These windows would really only be needed for sound reduction in the southern region. Don’t be oversold on the energy efficiency of triple pane in hotter climates. The only benefit in Kentucky for triple pane, in my opinion, is for sound reduction. Triple pane is a great option for sound reduction in homes that are in high traffic areas.
We know there are a lot of options, and we try to make this a simple process for you! You really only need double pane with LowE and Argon Gas filled panes. This is what we build into all of our windows at The Window Source of Lexington. Don’t get overwhelmed! We can show you a demonstration and make the process extremely simple.
