Install New Slider Windows for Your St. Louis Home

Close-up of a slider window with a view of trees outdoors. White wall around window.When considering replacement windows for your St. Louis home, slider windows offer many advantages over traditional options.

Slider windows, also known as sash or sliding windows, open from side to side rather than up and down. They comprise two panes of framed glass situated parallel to each other.

Single-hung slider windows allow only one pane to slide open while the other remains stationary in its frame. The double-hung style allows both panes to slide open and closed and even tilt inward or outward for ventilation.

Advantages of Installing Slider Windows

While slider windows were once only available to fit small spaces, you can now custom-design your sliding windows to fit your design needs. You can use sliding windows for purposes like:

  • Brightening a small space over the kitchen sink
  • Complementing bay windows
  • Bringing in more natural light with door-sized sliders
  • And more

Other advantages of sliding windows include:

  • Ease of operation: Slider windows effortlessly slide horizontally on their tracks, eliminating the need to lift heavy, traditional windows.
  • Ease of cleaning: Slider windows can be easily removed from their tracks to allow for thorough cleaning of the inside and outside surfaces.
  • Minimal maintenance: Sliding windows have fewer parts than conventional windows, meaning less chance of breaking vital parts that control operation.
  • Energy efficiency: You can add special coatings to your slider windows to increase insulation and reduce energy bills.

  • Glass options, such as obscure, tinted, and tempered glass, allowing for a uniquely elegant style
