When you start looking for replacement windows in Phoenix, AZ, you might quickly realize the process is more complicated than you thought. Sellers and manufacturers sometimes use jargon, assuming you know what they are referring to. And if you don’t understand the terms, it can lead to confusion. We want to help alleviate that frustration for our customers. Here is a break down on the window sash and why it is such an important part of the window assembly.

What is a Window Sash?

A sash is a single window pane and its surrounding components, whether the window is fixed or operable. Sliding windows have two sashes, as do single and double hung windows. Casement, awning, and picture windows typically have one sash.

Parts of a Window Sash

A window sash has several components. Here are some of the key parts:

• Rails and stiles. The top and bottom edges that surround the glass pane are called rails and the vertical edges on the left and right are called stiles. The border surrounding the glass pane comes in a variety of materials and usually matches the material used for the window frame.
• Sash pulls. Operable sashes in replacement sliding windows have areas that make opening and closing easy. They can be handles, raised areas, or indentations.
• Tilt sash release. Some modern replacement windows with operable sashes actually tilt inside for easy cleaning and maintenance. The tilt sash release is a latch that engages this function.
• Sash lock. For better security, this is a piece of hardware that latches when the window is closed. Sliding windows lock at the joining stile. Single and double hung windows latch at the joining rail. And casement and awning windows have locks against the window frame.
• Glazing. This is the term window professionals use for the glass. You can get replacement windows with single, double, or even triple glazing—meaning one, two, or three panes of glass. These extra layers provide more energy efficiency and help insulate your home against leaks, heat transfer, and unwanted noise.
• Modern manufacturers seal glazing into the framework using gaskets. These rubber seals are made of thermoplastic vulcanizates (TPVs) to improve efficiency and keep the windows from rattling.
• Gas fill. That is not your typical oxygen between the panes of glass on your replacement windows. Manufacturers fill the space between window panes with an inert gas, typically argon or krypton, to increase insulation and prevent leaks.
• If you see a grid or grille diving a window pane, but only for aesthetic purposes, then you are looking at muntins. But muntins are often confused with mullions, which are thicker components which separate adjoining windows from each other.

Do I Need Replacement Windows or just a Sash?

In some cases, you will not need to replace the entire window. Sometimes just replacing the sash will be enough. You can get standard and custom sash kits that fit perfectly into the existing frame. However, you want to talk to a professional to make sure sash replacement is a viable option.
