A window sash is the portion inside a single framing section, including those framing pieces and the glass attached to them. It is not the same as a full window frame, which is the frame around the entire window opening. For example, a double hung window has two sashes, but only one frame.

Bay and bow windows are more alike than they are different, which is why they are so often listed together. Both are combination windows that extend out from their walls, both have the option of window seats, and both are beautiful additions to your home. The key difference is that a bay window consists of three windows: one picture window in the center and two casement or double hung windows on either side. A bow window consists of four, five, or six windows, all of which are casements or double hungs. Instead of extending at sharp angles, a bow window is a gentle curve.

Visible Transmittance (VT) is a measurement of how much visible light (the spectrum of light we can see) comes through a piece of glass. VT is expressed as a number between 0 and 1. Obscure, privacy, and tinted glasses have lower VT than normal glass.

Argon is an inert, nontoxic, invisible, odorless gas that is used to fill the space between the panes of glass in double- and triple-paned windows. Argon gas in windows helps reduce the amount of heat transferred in and out of your home. Because the molecules that compose argon gas are heavier than those of air, the gas functions as a much more efficient heat barrier than air, so the argon gas helps keeps your home well insulated and energy efficient.

Krypton is actually a chemical element; it's an inert gas like argon that is used to insulate windows and reduce heat transfer. The reason Mr. Rogers doesn't use krypton is that it costs up to 100 times as much as argon, and insulates only marginally better. And in case you're wondering, the element's name came before the comic book; krypton gas was discovered in 1898.
