The Importance of Sashes in Window Replacement

When considering a Milpitas, CA window replacement, one of the key elements involved is window sashes. Knowing what window sashes do and why they’re important to the structure of windows can help you know if whether you need to repair your windows or invest in window replacements.   

Window sashes are the part of the window that holds the glass of the window in place (the frame of a window is the setting, including the window sill, that the window sits in).   

Window sashes are installed into window frames and may or may not be movable. On single-hung windows, the top window sash does not move, while the bottom window sash moves up and down. On double-hung windows, both window sashes can be raised or lowered. Sliding windows, which move horizontally, have only one window sash. Casement windows open with a crank and also have just a single window sash.  

Window sashes contribute to the longevity and durability of windows. The quality of any window is determined by its structural reinforcement. The stronger the structural reinforcement, the better the quality of the window and the longer it will effectively do its job.  

Aside from allowing you to open and close windows, window sashes are often critical to determining critical issues and problems with your windows.  

Window sashes must work properly in order to fulfill their function in window design. If you have windows that are stuck or that you’re unable to open and close, the first thing to look at as a probable cause is the alignment of the window inside the frame.  

Often, as the foundations of homes settle, windows get out of alignment because they no longer sit evenly in their opening in the house.   

Sometimes this is easily resolved by simply replacing the window sashes (although this is often just a temporary fix), but many times it requires that window replacements be done. If your home’s windows haven’t been replaced in ten or more years and your energy bills are creeping higher each year, it might be a wise investment to replace your windows.   

Another reason that window sashes get stuck and no longer move or move properly is because the tracks they are on get dirty over time and the grime inhibits free movement of the window. You can use a small amount of a solvent like W-D40 to clean the grime off the window tracks to see if that allows unrestricted movement of the window sashes. If it does not, then a windows replacement may need to be done.  

Two types of windows material are particularly susceptible to window sash problems.   

Wood windows are beautiful, but wood window sashes are especially vulnerable to damage such as swelling, shrinking, or rotting, which can make it difficult to move the windows up and down.  

Aluminum window sashes tend to oxidize, causing rust, and they can also increase sweating and condensation on window glass, which means the windows are leaking air. These will drive power bills higher and make your home significantly less comfortable both in winter and in summer.  

Window sashes that do not function properly lower the overall value of your home. If you are preparing to sell your home, investing in window replacements will make your home more attractive to prospective buyers, not just because of functionality, but because new window replacements can dramatically increase the curb appeal of your home.
