The short answer is that they function differently. Here’s what we mean:

A sash is the glass and the members framing the glass. Both double-hung and single-hung windows have two vertically stacked sashes.

With so many windows in this sunroom, the owners opted for single-hung windows. They didn’t need the option to open the top sash, too. These are 100 Series Single-Hung Windows with specified divided light grilles.

Single- and double-hung windows don’t have to be rectangular. You can get one of these windows with a round top — we call this shape Springline™. You’ll also find various arch shapes available as standard offerings. For the most flexibility in shapes, look to our E-Series product line. And if you’re leaning toward another product line, rest assured that the most popular Springline and arch shapes are available through various product lines.

Looking for a double-hung window in an arch or Springline shape(rectangular bottom with a circle top)? These are standard offerings among various product lines. And if you want the most customization options, start with the E-Series product line.
This is likely a detail you haven’t considered before, but sash size can be varied so the top and bottom sashes have different heights. While it might seem very subtle, it’s a detail that can add a lot of historic charm, especially on certain traditional home styles, like Cape Cods, for example. A taller bottom sash and shorter top sash is called a cottage sash. We also offer reverse cottage sashes, which are exactly what you’d expect — a shorter bottom sash and longer top sash.

This charming Shingle-style Colonial has E-Series Double-Hung Windows with colonial grilles and cottage sashes (on the first floor). Details like colors, grilles, and sash height can all help establish a home’s style.
From the style of the hardware to its finish, don’t overlook this detail! If you want the most traditional look, hardware with more detailing is just right — think curves, ridges, and similar flourishes. While more streamlined, low-profile hardware will suit a look that’s more modern or transitional — a contemporary take on traditional style. As for finishes, bright metals that contrast with the window and create a more pronounced look will feel more traditional. Finishes that blend in with the window feel more modern.
Either a double-hung window or single-hung window could work well in a replacement scenario. Here are a few replacement options to know about:
