Sliding Windows
Sliding windows provide simple operation, ventilation, and broad outdoor views in a design that works especially well for wider window openings. Instead of opening outward or moving vertically, the sash travels horizontally within the window frame.
Valdicass installs Pella® sliding windows throughout Chicago and the surrounding suburbs as part of replacement-window and renovation projects.
As a Pella Platinum Elite Certified Contractor serving Chicagoland homeowners since 1997, we can help you compare available sliding-window materials, configurations, glass, colors, grilles, and installation options for your home.
What Is a Sliding Window?
A sliding window—sometimes called a slider or gliding window—uses one or more sashes that move horizontally.
Because the operating sash remains within the plane of the window, a sliding window doesn’t require the exterior clearance needed for a casement or awning window that opens outward.
Its horizontal proportions can make it particularly useful for openings that are wider than they are tall.
Benefits of Sliding Windows
Sliding windows may be a good choice when you want:
- Easy horizontal operation
- Ventilation
- Broad outdoor views
- A window for a wide opening
- No outward-projecting sash
- Relatively simple operation
- Fiberglass or vinyl options depending on the selected Pella product
- Different glass and design options
The best window style depends on the opening, architecture, desired ventilation, accessibility, and appearance of the home.
Where Do Sliding Windows Work Well?
Sliding windows can work in many areas of a home, but they’re particularly useful where the shape or location of the opening favors horizontal operation.
Potential locations include:
- Bedrooms
- Living areas
- Family rooms
- Kitchens
- Basements
- Home offices
- Other wide window openings
Because the sash doesn’t project outside the home, sliding windows may also be useful near walkways, patios, landscaping, or other areas where an outward-opening window could be inconvenient.
Sliding vs. Double-Hung Windows
Sliding and double-hung windows operate differently.
A sliding window moves horizontally, while a double-hung window uses vertically operating upper and lower sashes.
The opening proportions can help determine which style makes more sense.
Taller openings often work naturally with hung windows, while wider openings may lend themselves to sliding configurations.
Architectural appearance is another consideration. Double-hung windows provide traditional vertical proportions, while sliders can create a broader horizontal appearance.
Sliding vs. Casement Windows
Casement windows are hinged along one side and open outward. Sliding windows remain within the frame and move horizontally.
A casement can provide different ventilation and a relatively uninterrupted glass area, while a sliding window doesn’t require exterior clearance for an open sash.
The right choice depends on the opening, view, ventilation, accessibility, and architectural design.
Sliding vs. Picture Windows
A picture window is fixed and doesn’t open.
A sliding window provides ventilation through an operating sash.
If ventilation isn’t required, a fixed window may provide a simpler solution with a larger uninterrupted glass area. If the room needs both ventilation and broad views, a sliding window or combination of fixed and operating windows may be worth considering.
Valdicass can help determine which configuration works best for the opening.
Pella Sliding Window Options
Pella’s replacement-window portfolio includes multiple materials and product collections, but available sliding-window configurations vary by series.
Valdicass can help determine which current Pella sliding products are appropriate for the dimensions, design, material, and performance requirements of your project.
This avoids choosing a window based on an outdated product line or assuming every Pella series is available in every operating style.
Pella Impervia® Fiberglass Sliding Windows
Pella® Impervia® provides fiberglass window options for homeowners interested in a durable, relatively low-maintenance frame material.
Depending on current product availability and the required configuration, Impervia can be considered for sliding-window applications.
Fiberglass can be particularly appealing when homeowners want a low-maintenance alternative without choosing a wood window.
Valdicass can help you compare the available Impervia styles, colors, glass, screens, and other options for your project.
Pella® 250 Series Vinyl Sliding Windows
Pella® 250 Series provides vinyl options for residential replacement projects.
Vinyl doesn’t require the routine painting or staining associated with traditional unfinished wood and can provide a relatively low-maintenance frame material.
Available sliding configurations, colors, glass packages, grilles, screens, and other options depend on the selected product.
Energy-Efficient Sliding Windows
Energy performance depends on more than the operating style of the window.
The complete assembly—including frame construction, insulating glass, Low-E coatings, weatherstripping, size, orientation, and installation—contributes to performance.
When comparing specific sliding windows, ratings such as U-factor and Solar Heat Gain Coefficient (SHGC)provide useful standardized information.
Depending on the selected Pella product and configuration, different glass options may be available.
Valdicass can help you review performance information for the specific windows you’re considering, rather than relying on broad energy-savings claims.
Glass Options
Glass can influence comfort, energy performance, safety, and appearance.
Depending on the selected Pella product and configuration, homeowners may have options involving:
- Insulating glass
- Low-E coatings
- Glass packages
- Applicable safety glazing
- Other available glass options
The appropriate glass depends on the window, orientation, location, and project requirements.
Do Sliding Windows Have Grilles?
Yes. Depending on the selected Pella product and configuration, sliding windows can be available with grille options.
Grilles can help coordinate a sliding window with the architectural character of the home and with other window styles used throughout the property.
For homes with traditional architecture, grille patterns may help integrate a wider sliding window with surrounding windows.
For contemporary designs, homeowners may prefer fewer grilles or a cleaner area of glass.
Colors, Hardware & Screens
Sliding windows can be customized with different design options depending on the selected Pella product.
Available choices may include:
- Interior colors
- Exterior colors
- Grille patterns
- Hardware
- Screens
- Glass options
Not every option is available with every product or configuration, so selections should be made based on the actual window being specified.
Replacing Existing Sliding Windows
You can replace existing sliding windows with new ones, but replacement is also an opportunity to evaluate whether the current style is still appropriate.
Depending on the opening and project requirements, homeowners may consider:
- A new sliding window
- Casement windows
- Fixed windows
- A combination of fixed and operating windows
- Another compatible window configuration
The existing style doesn’t automatically determine what must go back into the opening.
Valdicass evaluates the opening, dimensions, architecture, desired operation, and installation requirements before ordering replacement windows.
Replacing Another Window Style With a Slider
In some situations, an existing window can be replaced with a sliding configuration.
Whether this makes sense depends on factors such as:
- Opening dimensions
- Existing frame
- Available Pella products
- Ventilation requirements
- Applicable egress requirements
- Interior use of the space
- Exterior conditions
- Desired appearance
A wide opening that currently contains another window style may be a candidate for a sliding window, but the complete project should be evaluated first.
Sliding Windows & Egress Requirements
For bedrooms and other locations that require an emergency escape and rescue opening, selecting a window based on style alone isn’t enough.
The applicable window needs to meet the required clear opening dimensions and area for the project and jurisdiction.
A window’s overall frame dimensions don’t necessarily tell you how large the usable opening will be when the sash is open.
Valdicass evaluates applicable project requirements when specifying replacement windows for these locations.
Pocket & Full-Frame Sliding Window Replacement
Sliding windows may be installed using different replacement methods depending on existing conditions.
Pocket Replacement
With pocket replacement, portions of the existing window frame remain, and the new window is installed within the existing opening.
This may be appropriate when the existing frame and surrounding conditions are suitable.
Full-Frame Replacement
Full-frame replacement involves more complete removal of the existing window assembly.
This can provide greater access to the opening and may be appropriate when existing frames need to be removed, surrounding conditions require attention, trim is changing, or a different window configuration is being installed.
Valdicass evaluates the existing opening before determining the appropriate approach.
Professional Pella Sliding Window Installation
Window performance depends on more than the product itself.
Accurate measurements, opening preparation, positioning, fastening, insulation, sealing, water management, and finishing all contribute to the completed installation.
Valdicass specializes in Pella replacement window installation and can help you determine whether a sliding window fits your opening or whether another style better meets your objectives.
