Casement Window Replacement and Installation

A casement window has an operable sash hinged along one vertical side. It opens outward like a door and is normally controlled by a crank operator. This design provides a clear view, useful ventilation and a compression-style closing action when the sash is shut.

Falcon WD supplies and installs custom vinyl casement windows across the GTA and selected Ontario service communities. Each unit is ordered to confirmed dimensions and approved specifications, including the frame, glass package, colour, hardware, screen and installation method.

How Casement Windows Work

The sash is attached to the frame with hinges on one side. Turning the crank moves the sash outward, while the interior screen stays in place. When the window closes, the operating and locking hardware draws the sash toward the frame seals.

The exact opening angle, locking system, weatherstripping and hardware specification vary by manufacturer and product line. These details should be confirmed in the written quote rather than assumed to be identical on every casement window.

Where Casement Windows Work Well

  • Kitchens: crank operation can be convenient above many sinks and countertops.
  • Bedrooms and living areas: the full operable sash can provide useful ventilation and a clear view.
  • Taller openings: side-hinged proportions often suit openings that are taller than they are wide.
  • Combination windows: casements can be paired with fixed casement or picture units where both ventilation and larger glass areas are desired.
  • Wind-exposed locations: an appropriately specified casement can provide strong air-sealing performance when closed and locked.

Because the sash projects outside the wall, exterior clearance must be checked. Walkways, decks, railings, shrubs, rooflines and neighbouring sashes can affect whether a casement is appropriate for the opening.

Benefits of Vinyl Casement Windows

Ventilation and an Unobstructed View

A casement sash opens away from the frame rather than sliding behind another sash. This allows a large portion of the opening to be used for ventilation and avoids the meeting rail found in many sliding or hung window configurations.

Compression-Style Closing

As the sash closes, the hardware draws it against the perimeter seals. Actual energy and air-leakage performance still depends on the complete certified configuration, including the frame, glass, spacer, weatherstripping and installation.

Interior Screen and Convenient Operation

The screen is positioned on the room side because the sash opens outward. A crank operator can also make the window easier to use in locations where lifting or sliding a sash would be inconvenient.

Flexible Design Combinations

Casement units can be installed on their own or combined with fixed casement, picture, transom or other operating windows. Available combinations depend on structural limits, unit size and the selected product line.

Glass, Colours and Configuration Options

Casement windows are custom ordered, and the available options vary by manufacturer, series and unit size. The written quote should identify the exact configuration being supplied.

  • Double-pane or triple-pane insulated glass, subject to product and size limits.
  • Low-E coatings and gas-filled insulated glass packages where available.
  • Clear, tinted or privacy glass.
  • Interior and exterior colour choices offered by the selected product line.
  • Decorative grids and selected hardware finishes.
  • Single casement units, paired casements or combinations with non-operable windows.

ENERGY STAR certification is configuration-specific. The exact model and glass package must be verified rather than assuming that every casement window has the same rating.

Casement vs. Awning vs. Fixed Casement Windows

Window style Hinge or operation Opening direction Typical purpose
Casement Hinged on one vertical side Opens outward like a door Ventilation and clear views in taller openings
Awning Hinged at the top Opens outward from the bottom Ventilation in wider or shorter openings
Fixed casement Non-operable Does not open Natural light and matching sightlines without ventilation

Review our awning window page, fixed casement window page or the main window replacement service page to compare additional styles.

Casement Window Sizing and Installation

Casement windows are made to order, but minimum and maximum dimensions are not unlimited. Permitted sizes depend on the frame system, glass package, sash weight, hinge and operator hardware, and manufacturer engineering limits.

Before ordering, Falcon WD reviews the existing frame, sill, exterior finish, jamb depth, interior finish and required exterior clearance. The quote should identify whether the project uses a retrofit installation or a more extensive full-frame replacement.

A casement style does not automatically make a bedroom or basement opening egress-compliant. Any egress requirement must be assessed separately using the clear opening, operating method, sill height and applicable project conditions.

Casement Window Cost and Estimates

Pricing depends on the opening size, frame and glass package, colour, hardware, installation method, exterior capping and any required finishing or repair work. Casement windows should not be described as universally cheaper or more expensive than every other style because the final configuration determines the cost.

For an initial review, send the project address, approximate dimensions and clear photos of the complete opening from inside and outside. Final measurements must be confirmed before custom windows are ordered.

Casement Window Frequently Asked Questions

What is a casement window?

A casement window has an operable sash hinged along one vertical side. It opens outward like a door and is normally controlled by a crank operator, while the screen remains on the interior.

Where do casement windows work best?

Casement windows work well in bedrooms, living areas, kitchens and other rooms where ventilation and a clear view are priorities. They are also practical above many sinks or counters because the crank can be easier to operate than lifting or sliding a sash.

Do Falcon WD casement windows include screens?

Opening casement windows supplied by Falcon WD include an interior screen unless the written quote states otherwise. The exact screen frame, mesh and retention system depend on the selected product line.

Can casement windows be ordered with triple-pane glass?

Triple-pane glass is available for many casement window configurations. The permitted unit size, sash weight, hardware and certified performance must be confirmed for the exact product before ordering.

What is the difference between a casement and an awning window?

A casement window is hinged at the side and opens outward like a door. An awning window is hinged at the top and opens outward from the bottom. The better choice depends on the opening proportions, ventilation goals and available exterior clearance.

Can casement windows be cleaned from inside?

Cleaning access depends on the sash size, opening angle and hardware design. Some casement configurations provide good access to both sides of the glass from indoors, while other locations or larger units may still require exterior access.

Does a casement window automatically qualify as an egress window?

No. Egress compliance depends on the clear opening, operating method, sill height, exterior conditions and the requirements that apply to the specific room and project. The proposed unit must be assessed separately before it is described as egress-compliant.

How long does a casement window replacement project take?

Production is typically about three to four weeks after final measurement and deposit, although product, colour and seasonal demand can affect timing. On-site installation time depends on the number of units, installation method and condition of the existing openings.
