Traditional vertical windows with a fixed upper sash and an operable lower sash.

A single-hung window has two vertically arranged sections. The upper sash stays fixed, while the lower sash slides upward to provide ventilation. As a result, this style keeps a traditional appearance without requiring an outward-opening sash.
Falcon WD supplies and installs custom vinyl single-hung windows across the GTA and selected Ontario communities. First, we review the opening, room use and installation conditions. Then we order the frame, glass, colour and finishing details listed in your quote.

The lower sash travels vertically inside the frame and overlaps part of the fixed upper section when open. Therefore, ventilation enters through the lower portion of the window.
The window does not project outdoors. That can make it practical near patios, walkways and other areas where an outward swing would be inconvenient. However, hardware, balance systems and tilt-in cleaning features vary by product line.
Single-hung windows suit many traditional and transitional homes. Their vertical proportions also coordinate well with other hung windows in the same elevation.
The lower sash opens within the frame. Therefore, the window can provide airflow without extending over an exterior walkway, deck or planting area.
Only the lower sash moves. As a result, the operating system is straightforward, while the upper section remains fixed.
Single-hung windows can work in bedrooms, living areas and other rooms where lower-section ventilation is suitable. The final choice should also consider cleaning access, required opening size and the room’s ventilation needs.
Manufacturers offer different options by frame series, size and glass weight. Therefore, the written quote should identify the exact product and glass package.
Some exact frame-and-glass combinations carry ENERGY STAR certification. However, the single-hung style name alone does not prove certification. We must confirm the selected model, size and glass package.
| Window style | How it opens | Ventilation | Common reason to choose it |
|---|---|---|---|
| Single-hung | Lower sash slides upward | Lower opening only | Traditional vertical style with one operable sash |
| Double-hung | Upper and lower sashes move | Top, bottom or both | More ventilation and cleaning flexibility |
| Single slider | One sash slides horizontally | Side opening | Horizontal layout without an outward swing |
| Casement | Side-hinged sash opens outward | Full operable sash area | Wide opening and directional airflow |
For more detail, compare our double-hung windows, slider windows and casement windows. You can also review our main window replacement service.
Factories build single-hung windows to custom dimensions. However, sash weight, balance-system capacity, glass size and frame limits affect the final design. Therefore, Falcon WD confirms all measurements before production.
Before we quote the work, we check the old frame, sill, jamb depth and exterior finish. Then we select the correct installation method. A retrofit installation keeps more of the old frame, while full-frame replacement removes it.
Some single-hung windows allow the lower sash to tilt inward for cleaning. Other models use a different cleaning method. Therefore, Falcon WD confirms this feature before ordering instead of assuming that every single-hung window tilts.
A single-hung window provides ventilation through the lower opening. A screen normally protects the operable section, although screen size and layout depend on the product.
A single-hung window is not automatically an egress window. The clear opening through the raised lower sash must be assessed in normal operation, together with the rules that apply to the room and installation.
Several choices affect the price. For example, width, height, glass, colour, grids, installation method, exterior capping and interior finishing can change the total.
To start, send us the project address, rough sizes and clear photos from inside and outside. After that, we can review the likely scope. We will still confirm final measurements before ordering.
A single-hung window has a fixed upper sash and a lower sash that slides vertically to open.
A single-hung window has one operable sash, while a double-hung window has two operable sashes. Double-hung windows can provide ventilation from the top or bottom, while single-hung windows open from the lower section only.
Some single-hung product lines include a lower sash that tilts inward. This feature varies by manufacturer, model and size, so it must be confirmed in the quote.
A screen is normally provided for the operable lower section unless the written quote says otherwise. The exact screen size and layout depend on the product.
Many product lines offer triple-pane glass. However, the factory must confirm the exact size, glass weight and frame limits before ordering.
It may qualify only when the lower sash provides the required clear opening in normal operation and the complete installation meets the rules for that room. The window style alone does not confirm egress.
Interior glass is straightforward to reach. Exterior cleaning depends on the floor level and whether the selected lower sash tilts inward.
Production usually takes about three to four weeks after final measurement and deposit. Installation time depends on the number of windows and the condition of each opening.
Falcon WD can replace one single-hung window or include this style in a larger home project. In either case, the written quote will list the product, glass, installation work and finish details.
