Custom Slider Window Replacement and Installation


For fresh air and a fantastic view, consider slider windows for your home. Slider windows open horizontally, allowing for quick ventilation with minimal maintenance. That’s why this type of window is such a popular choice for rooms that require regular ventilation.

What Is a Slider Window? 

Slider windows are similar to double-hung windows. Yet, the key difference is that sliders glide horizontally, while double-hung slide vertically. This type of window can be configured in a few ways, including: 

  • Horizontal Sliders – One fixed pane and a sliding pane that can move side to side, left to right.  
  • Double Sliders – Both panes slide, allowing for maximum ventilation.
  • 3-Lite Sliders Slider windows can be installed alongside a fixed picture window to allow for ventilation on either side. 

Slider windows are common on Mid-Century Modern homes, as sliders were a popular choice in the 1950s and 1960s. Yet, their contemporary look makes them an ideal choice for a wide range of home styles.  

Advantages of Slider Windows 

Slider windows have numerous benefits, and that’s why they’re one of the most common types of windows installed on homes and commercial properties today. Some key benefits of slider windows include: 

  • Quick Operation – Sliders are ideal in spaces that require constant ventilation. In restrooms, above sinks, or in bedrooms, slider windows are a great solution. 
  • Little Maintenance – Sliders have fewer parts, and therefore require less frequent maintenance than double-hung or crank windows. 
  • Expansive Views – Slider windows tend to be wider than they are tall. That’s why they’re great for showcasing views with a larger horizontal frame. 
  • Contemporary Look – Replacement slider windows tend to have a clean appearance that’s perfect for new construction and contemporary homes. 

Disadvantages of Slider Windows 

Slider windows are an ideal choice in nearly any room in the home. Yet, there are some disadvantages to slider windows that you might consider. They include: 

  • Tough to Clean – Unfortunately, you can’t clean the exterior of the window from the inside, like you can with casement or double-hung windows. This makes exterior cleaning a challenge. 
  • Size Limitations – Horizontal slider windows tend to be best for wider window openings, while double-hung or single-hung windows are best for taller openings. 
  • Track Cleaning – The tracks of a slider window can collect dust and debris. The tracks should be cleaned regularly for smooth operation. 

Common Uses for Slider Windows 

Wondering how you can use slider windows in your home? These windows work great as the main window in any room, yet, there are some specific cases that are well-suited to sliders. They include: 

  • Egress Windows – Sliders work well as egress windows, thanks to their simple operation and wider openings. 
  • Natural Ventilation – Sliding windows are ideal for spaces that require regular ventilation. They’re better than crank windows or double-hung windows, thanks to their streamlined operation. 
  • Near Walkways & Patios – Unlike crank windows or bay windows which protrude out, sliders are fixed and won’t hang out over walkways and patios when open.
  • Wide Openings – For large, horizontally-orientated openings, slider windows make one of the best, most efficient choices.
