We take windows for granted. We use them every day to get some fresh air or even just brighten up our rooms. But there’s more to windows than meets the eye. Today, we discuss four fun facts about windows. 
The White House Has a Total of 147 Windows
To give you a sense of scale, the average household has about eight windows. Imagine how much work it takes to keep those windows clean! But, alas, the building with the most number of windows goes to the Burj Khalifa, with a whopping 24,000 windows. It takes a team of 36 window cleaners and 3 months to clean all windows top-to-bottom, using state-of-the-art cranes and special suits.
Grilles Were a Necessity
You’re probably more familiar with removable grilles, but in the past, they were absolutely needed. During the Renaissance period, glassmaking technology was limited to manufacturing glass panels several inches across. The earliest examples of glass windows featured several glass panels held together by what we know today as grilles. Today, you can have replacement windows with glass panels of virtually any size; grilles serve a more decorative function.
The Origin of the Word “Fenestration”
You may have heard of the word “fenestration” in reference to windows and doors. It came from the Latin word fenestra, which translates as window. The term “fenestration” persists as a general term for windows, doors and skylights. In fact, there is an organization called the National Fenestration Rating Council® (NFRC), which is responsible for the energy performance labels that are affixed to new doors and windows.
Invisible Insulation
You may have been wondering how “insulated glass” works without visible insulation. Unlike window frames and sashes, conventional insulation can’t be inserted into glass, which happens to be a naturally conductive material. The solution is an assembly of two glass panels, separated by insulated spacers. The airspace between glass panels dramatically reduces conductivity, which slows down heat transfer between its indoor and outdoor sides. This has proven to be so effective that Renewal by Andersen® has made it a standard component of our replacement windows.
