What Are Slider Windows?

One of the most common types of windows, slider windows are windows that open sideways or up and down, with one pane gliding over the other. This feature makes slider windows ideal for openings that are longer or wider than they are tall.

Slider windows can be:

  • Single-hung, opening from the top or bottom or from the right or left side
  • Double-hung, opening from both the top and bottom or from both the right and left side

Should I Choose Horizontal or Vertical Sliding Windows?

Your needs and preferences will determine whether vertical or horizontal sliding windows are your better option – and the experts at Zen Windows Denver can help you make the right choice!

In general, both horizontal and vertical sliding windows:

  • Look the same when closed
  • Provide insulation, natural light, and ventilation
  • Are easy to use and clean

The differences are that:

  • Vertical sliding windows can lose strength over time. This can lead to open windows suddenly slamming shut.
  • Horizontal sliding windows can be more difficult to operate when objects get lodged in the tracks. The runners in these can also wear over time, making it harder to open and close these windows.

Advantages of Slider Windows

Available in various shapes, sizes, and styles, slider windows offer many benefits, including:

  • More light & great views: Letting in natural light, slider windows can brighten rooms while providing picturesque views of the outdoors.
  • Easy & natural ventilation: With a gentle push, slider windows can be easily opened, letting in air and naturally ventilating rooms.
  • Low maintenance: Slider windows have fairly simple designs and relatively few parts, allowing them to function with little to no maintenance for years. Whenever these windows need to be cleaned, removable frames make it quick and easy.
  • Architectural compatibility: Available in custom styles and sizes, slider windows can be designed to match the style of any home. From ranch and Tudor homes to art deco and mid-century modern designs, slider windows work well with – and can enhance – just about any style.

Our Slider Windows Are Made for High Altitudes

Many slider windows are built for extreme cold or extreme heat. But not all windows are designed for high altitudes. Zen Windows Denver only installs high-altitude windows in:

  • Boulder
  • Castle Pines
  • Castle Rock
  • Denver
  • Golden
  • Highlands Ranch­
  • Littleton
  • Parker

As you ascend higher, air pressure decreases and air becomes less dense. This makes it harder to maintain a strong seal on windows. It also affects the way the gas between the panes expands and contracts with changing temperatures.

Zen Windows Denver glass professionals understand what special requirements should be met for high-altitude slider windows:

  • Argon or krypton gas infills keep heat inside your home
  • Low-E coating for the summer heat
  • Multiple panes separated by small air gaps
  • Non-metallic spacers
  • Superior quality frame material

When you partner with us for slider window installation, you can be sure your windows are customized for high altitudes, extreme weather, and energy efficiency. Your beautiful slider windows will be architecturally compatible with your structure and a terrific upgrade to your property.

You’ll realize energy savings (and save money) with high-altitude slider windows. Your property value and curb appeal will increase, making slider windows a good investment.
