Single Slider Windows
Single slider windows are one of the most practical choices for Calgary homes — and not just because of how they operate. In a city where Chinook winds can push cold drafts through even a well-built frame, the horizontal sliding design removes one vulnerability entirely: there is no sash projecting outward into the wind. One panel stays fixed, one glides smoothly on a precision track, and the entire unit seals flat against the frame when closed. Window Craft has been installing single slider windows across Calgary for over 10 years, completing more than 15,000 window and door projects with factory-direct pricing and a 25-year fully transferable warranty on every installation.

Benefits of Single Slider Windows
- 25 Years Window Warranty
Most window pages tell you what a single slider is. This one tells you why it works specifically well in Calgary.
Calgary sits at the edge of the foothills, where wind direction and temperature can shift dramatically in a matter of hours. During a Chinook, outdoor temperatures can rise 20°C in under an hour, putting thermal stress on window frames and seals. Single slider windows handle this well because the vinyl frame expands and contracts as a single unit — there are no outward-swinging hinges or crank hardware exposed to those temperature swings.
For basement installations, the horizontal sash movement is equally practical. Egress requirements under the Alberta Building Code specify minimum opening dimensions, and a slider sash can be sized to meet those requirements without projecting into a window well or below-grade landscaping.
Window Craft installs each unit with fusion-welded frame corners, continuous perimeter weatherstripping, and multi-chambered vinyl profiles. These details are not visible once the window is in, but they are the reason our installations still perform cleanly a decade later.

Single Slider Windows Features
Windows Colors
Window Craft offers more than 10 colour options for single slider windows, including standard white, matte black, warm wood-look finishes, and a range of contemporary tones. Colour is applied through the full frame profile rather than painted on the surface, so it will not peel, chip, or fade under Calgary’s intense UV exposure and winter conditions. Whether your home has modern hardie board cladding, traditional stucco, or brick, there is a profile in our selection that will sit cleanly against it.
Frame and Construction
Every single slider window we install uses a multi-chambered uPVC frame profile that does two jobs at once: it holds its shape under structural load while trapping air in separate chambers to slow heat transfer. Fusion-welded corners bond the frame at each joint rather than mechanically fastening it, which eliminates the gaps that develop in corner-joined frames over time. This matters in Calgary because freeze-thaw cycling is relentless — a mechanical joint that is tight in October can open up by March.
- Multi-chambered uPVC frame for thermal and structural performance
- Fusion-welded corners — no mechanical fasteners at the joints
- Continuous perimeter weatherstrip including sash corners
- Precision roller and track system for smooth, quiet operation
- Multi-point locking for a tight, secure sash closure
- Concealed internal drainage channels to protect the sill
- Full-overlap insect screen — removable from inside the home
- Meets Alberta Building Code egress requirements in select configurations
Glass Type
The glass package you choose has more impact on your energy bill than any other part of a window. We offer both double and triple-pane configurations, and we are direct about the difference.
Double Glass
A double-pane unit has two glass panels separated by a sealed spacer filled with argon gas. Low-E coating on the inner surface reflects heat back into the room during winter and deflects solar gain in summer. This is the standard configuration and performs well in most Calgary homes, particularly in above-grade rooms with reasonable sun exposure.
Triple Glass
A triple-pane unit adds a third glass layer and a second argon-filled cavity. The result is a measurable improvement in both thermal resistance and noise reduction. For Calgary homes on exposed lots, near busy roads, or in older neighbourhoods where the existing windows are single-pane, the upgrade cost pays back in heating savings faster than most homeowners expect. We run the numbers during your in-home consultation so you can make the call with real figures, not estimates.
Single Slider windows are available in both the Ultraslim and Classic series
Ultraslim Series
With a deeper 4-9/16″ frame and a slimmer 2-7/8″ visible profile, the UltraSlim Series with hidden gasket delivers a sleek, modern look while maximizing glass area. It is designed for seamless integration into new construction and larger openings.
Classic Series
A proven 3-1/4″ frame depth with a standard profile, the Classic Series is ideal for retrofit and replacement projects. It delivers excellent thermal performance, a familiar aesthetic, and reliable compatibility with a wide variety of installation conditions.
What Single Slider Windows Cost in Calgary
The cost of a single slider window installation in Calgary depends on four things: the window size, the glass package you choose, the frame colour, and the condition of the existing rough opening. A standard double-pane single slider in a common bedroom size typically falls in the mid-range for replacement windows — above budget box-store options, well below premium European imports.
Because Window Craft buys factory-direct, there is no distributor markup in our pricing. We provide a written quote after an in-home measurement, so there are no surprises on installation day. We also offer financing options for larger projects, including full-home window replacements.
The best way to get an accurate number is a free in-home consultation. We measure every opening, assess the frame condition, and give you a firm quote on the spot.

FAQ
A single slider window has two panels side by side in one frame. One panel is fixed and does not move. The other slides horizontally along a track to open. Because nothing swings outward or inward, it works well in rooms where exterior or interior clearance is limited — a walkway outside, a piece of furniture inside, or a basement window well.
A single slider has one moving sash and one fixed panel. A double slider has two sashes that can both be opened, which allows more ventilation and makes cleaning easier since both panes can be reached from inside. Single sliders are simpler, slightly more affordable, and the right choice when ventilation on one side of the opening is sufficient.
Cost depends on size, glass package, colour, and the condition of the existing opening. Window Craft uses factory-direct pricing, which removes distributor markup and keeps costs competitive. We provide a fixed written quote after measuring your openings — call 587.718.8851 or book a free in-home consultation to get an accurate number for your project.
Yes, in select configurations. The Alberta Building Code requires bedroom egress windows to meet minimum clear opening dimensions. A single slider can be sized to meet those requirements, and the horizontal operation is practical for basement installations where exterior clearance is tight. Our team confirms compliance during the consultation and quotes the correct configuration for your opening.
Most single slider replacements take one to two hours per window. A full-home project with several windows is typically completed in a single day. We work efficiently to keep the home closed up as much as possible, which matters in winter. The old windows are removed, the new units installed and sealed, and the interior and exterior trim finished before we leave.
They can be, when built and installed correctly. The key factors are the glass package — double or triple pane with Low-E coating and argon gas — the quality of the weatherstripping around the sash, and the installation itself. A window that is not set level or sealed properly will leak air regardless of the glass spec. Window Craft supplies and installs, so we control both sides of that equation.
Every window we install is protected by a 25-year fully transferable, non-prorated warranty. Transferable means it moves with the home when you sell. Non-prorated means the full coverage applies throughout the warranty period, not a declining scale. It reflects the quality of the products we install and the standard of our installation work.
No. Replacing windows in existing openings does not require a building permit in Calgary when the rough opening size is unchanged. The structural framing is not altered, so the work falls outside City of Calgary permit requirements. If you are planning to enlarge an opening or cut a new one, that is a structural change and a permit would apply. We clarify the specifics for your project at the consultation stage.
