If you’re not familiar with the design and functionality of your home’s windows, you might be unprepared when it’s time to repair or update them. In this post, we'll share what is a window sash and why they are important to the design of the window.

What is a Window Sash?

Window Sash DrawingA window sash is the part of the window that holds the glass and the framework around the glass to keep it in place. Window sashes are fitted into the window frame and may or may not be movable. Most windows in newer homes are sash windows.

Importance of a Window Sash

Window sashes are very important to the overall construction and durability of the window. It is crucial that vinyl window sashes are multi-chambered, fusion-welded and reinforced so they don’t distort over time. A window sash that is distorted can cause the window to leak and not lock properly. Structural reinforcement determines the quality of the window. For example, Stanek Windows’ sashes are fully reinforced on all four sides using non-conductive FIBERMAX™ reinforcement. This feature offers superior structural strength against sagging, bowing and warping.

How to Know if You Have a Problem with Your Window Sash

Since window sashes are an important part of window design, it’s imperative that it works properly. If the window is stuck and unable to open and close, then it may indicate an alignment problem. This can usually be resolved with minor adjustments, but if not, you may need to replace your window sash or windows. If your windows haven’t been replaced in several years, then it may be wise to purchase replacement windows for your home. While the initial cost may be high, new windows may lower your energy bills and increase the overall value and curb appeal of your home.

Wood Windows

Older homes with wood windows are often plagued with problems like wood swelling, rotting or shrinking. This can cause the window to be difficult to move up and down. With the latest technology in vinyl windows, however, homeowners can now enjoy the look of traditional wood windows without the problems associated with wood. Stanek windows with interior woodgrain finishes, for example, have all the beauty of wood but the low maintenance and durability of vinyl.

Aluminum Windows

Many older homes have aluminum windows. These were popular particularly during the 1960s, but many homeowners encountered problems when the aluminum oxidized. Aluminum also promotes sweating and condensation inside the panes of glass. Today’s vinyl windows are far superior, as they are tough enough to withstand all types of weather, including the sun’s heat.

Though replacement window sashes can be a temporary fix, installing brand new energy-efficient windows will offer the best performance in the long run. Typically, the custom-milled sash design offers a precise fit and is often 100% maintenance free. Vinyl replacement windows by Stanek Windows are built to fit your home and offer structural reinforcement, which allows your new windows to be energy efficient and durable.

Some additional considerations when you purchase replacement windows:

  • It’s important to work with a reputable company that has been in business for a significant amount of time and is able to offer references.
  • A high-quality replacement window with structural reinforcement offers better protection against break-ins as it’s stronger and more secure.
  • Newer replacement windows are easier to clean and will give your family many years of reliable use.
