Single Slider Windows in Ottawa
A single slider has one fixed pane and one sash that slides sideways. Ours also tilts inward so that you can wash the outside glass without a ladder. Nothing swings out of the frame, which makes it the practical pick for openings beside a deck, a walkway, or a fence.

Is a Single Slider Right for This Window?
A good fit when:
- A sash can’t swing outward (deck, porch roof, walkway, close fence)
- You’re replacing an existing slider and want the same look
- It’s a basement or ground-floor window you want to open often and easily
- Budget matters: with no crank or hinges, it’s usually one of the lower-cost opening styles
Choose something else when:
- The window faces a strong prevailing wind. A slider’s air leakage is tested at 0.5 L/s·m²; a casement seals tighter.
- You want both sides to open: look at a double slider.
- The opening is wide, and the view matters most: an end vent slider keeps a large fixed centre.
Pick the Glass by the Wall It Faces
These are the tested results for our single slider (CSA A440.2). A higher Energy Rating (ER) is better; ENERGY STAR starts at 34.
| Glass package | U-factor | ER | Best for |
|---|---|---|---|
| Double pane, Low-E, argon | 1.60 | 34 | Budget rooms, meets ENERGY STAR |
| Double pane + i89 room-side coating | 1.40 | 36 | Most rooms; warmer inner glass, less condensation |
| Double pane, Low-E 366 (solar) | 1.60 | 26 | West or south rooms that overheat in summer |
| Triple pane, Low-E, argon | 1.10 | 40 | North walls, rooms near traffic noise |
| Triple pane + i89 | 1.05 | 40 | Coldest rooms; lowest heat loss |
Both triple-pane packages reach the ENERGY STAR Most Efficient level (ER 40). The solar package trades winter gain for summer comfort, so its rating is lower on purpose. We’ll suggest a package room by room at the estimate.
Cleaning Both Sides From Indoors
- Slide the sash a few centimetres open.
- Pull in the two tilt latches at the top of the sash.
- Tilt the sash toward you and rest it; both faces of the glass are now within reach.
- Tilt it back up until both latches click.
The screen lifts out the same way it went in, so you can wash it in the sink.
Single or Double Slider?
A single slider has one fixed pane, so there’s one less moving seal, and it usually costs less. A double slider lets either side open and lift out. If you’re unsure, we can mix them: double sliders in bedrooms, singles elsewhere.
