Features of

Casement Windows

Hinged Opening

These windows are hinged at the side and open outward like a door. This design allows for a wide and unobstructed opening, providing maximum ventilation and airflow into the room.

Crank Mechanism

The casement window is typically operated using a crank handle or lever. This mechanism enables easy and precise control over the degree of window opening, allowing you to adjust the ventilation according to your preference.

Airtight Seal

When closed, they create an airtight seal. The sash presses against the frame, minimizing air leakage and preventing drafts. This feature enhances energy efficiency and helps maintain a comfortable indoor temperature.

Single Pane or Multiple Panes

The casement window can be constructed with a single pane of glass or multiple panes divided by muntins. Single-pane casement windows offer unobstructed views, while multiple-pane windows provide additional insulation and can be designed in various styles, such as colonial or grid patterns.

Security Features

These windows often come with built-in locking mechanisms. These locks are embedded within the window frame, making them difficult to tamper with from the outside. Some also feature multi-point locking systems for enhanced security.

Versatile Design Options

Available in a wide range of sizes, shapes, and materials. They can be customized to suit different architectural styles and personal preferences. Whether you prefer a classic wooden frame, a sleek aluminium finish, or a contemporary vinyl design, there are options to complement any home style.

Easy Maintenance and Cleaning

They are relatively easy to maintain. Since they open fully, both sides of the glass can be accessed from the interior, simplifying cleaning tasks. Additionally, many casement windows are designed with removable sashes, making repairs or glass replacement more convenient.
