What is the difference between a Picture Window and a Picture Window Unit?

A picture window is a single, fixed, unit of glass that CANNOT open or close. The glass is set in a frame, hence the name; picture. Whereas, a picture window unit has a fixed window in addition to functional windows on either side. A window is not a picture window if it opens if the window opens it is a casement window. This glass is set into the window and has no operational function. Units are mulled (sealed) together to make them an entire removable unit as opposed to three separate windows. This is why they are called a unit and not considered a single picture window and two double-hung windows.

Picture Window Replacement

The size options of your replacement window are the size of your current picture window. Your options, due to size, for replacing your picture window include:

  • Double Hung Windows
  • 2 Lite Slider Windows
  • 2 Lite Casement Windows

Double Hung Window (DH)

Double Hung Window

Double-hung windows are the most common window we replace in homes. Double-hung windows operate by sliding up and down (vertically) and can come with either a half screen or full screen. They have easily removable sashes (glass with frame) for effortless cleaning. Double Hung windows are also great windows to use for window unit air conditioners as you can remove the bottom sash.

2 Lite Slider (2LS)

As opposed to sliding up and down (vertically) with a double a 2lite slider slides from side to side (horizontally). It is called a 2lite slider due to each of the two sashes (glass) being able slide open. These windows are typically used for openings that are wider than taller due to the width from the two sashes. This style is typically seen in condos and sunrooms.

2 Lite Casement (2LC)

A 2lite casement has two sashes side by side like the 2lite slider, but differs in the fact that these windows are crank out windows instead of sliding windows. A 2lite casement is when two casement or crank out windows are mulled (sealed) together into a single unit. This means that it is a single window unit and not two separate windows. Each sash has it’s own crank for operation meaning both can be open at the same time. One window opens to the left while the other opens to the right and each crank out to a 90-degree angle for ease of cleaning. These window units are typically used over a kitchen sink and in contemporary homes.

This is different from the 2lite slider and double hung where one sash ultimately covers the other sash while one is open. 2lite casement windows give you the freedom and airflow of both being open simultaneously.

Replacing Picture Window Unit

Due to the nature of Picture Window Units having a larger opening than a single Picture Window, there are a lot more options available for picture window replacement. For example, if your current window is 96 x 48 or 96 x 60 you have to then replace it with a window of the same dimensions.
