Energy efficiency is a complex equation. Everything from the glass to the frames affects thermal performance. And the window itself must be expertly installed for it to reach peak efficiency.
Window labels and ratings offer up the information you need for comparing products. But there are certain window features that impact energy efficiency that aren’t easily explained on a sticker. These six types of windows each contain at least one characteristic that secretly helps increase their energy efficiency.
1. Fixed Windows
Fixed picture windows don’t offer any functionality. But when it comes to energy efficiency, that’s actually a good thing! Since you can’t open a picture window, you never break its airtight seal. No other window style can make that claim.
Fixed windows are a great solution for parts of your home where you don’t need ventilation. Or in window combinations and a wall of windows where the airtight design can help keep large expanses of glass from feeling drafty.
