Casement crank windows have long been a popular choice among homeowners and builders alike. These versatile windows offer a unique combination of style, functionality, and energy efficiency that make them an attractive option for any home. In this comprehensive guide, we'll explore the ins and outs of casement crank windows, from their history and design to their benefits and installation process.
Casement windows have been around for centuries, with their origins dating back to medieval Europe. They were originally designed as large, single-pane windows that could be opened outward for ventilation and closed to protect the home's interior from the elements. Over time, the design of casement windows has evolved, with the addition of multiple panes, glazing, and other features to improve their energy efficiency and performance.
At its core, a casement crank window is a type of window that is hinged on one side and opens outward, typically using a crank handle. The crank mechanism allows for easy operation, making it simple to open and close the window as needed. This design offers several advantages, including better ventilation, increased security, and improved energy efficiency.
One of the key benefits of casement crank windows is their ability to provide excellent ventilation. Because they open outward, they can catch passing breezes and direct fresh air into the home. This is particularly useful in rooms that tend to get stuffy or have poor air circulation, such as kitchens and bathrooms.
Casement crank windows are also known for their superior security features. The locking mechanism is integrated into the window frame, making it difficult for intruders to pry open the window from the outside. Additionally, the crank handle can be removed when the window is closed, further deterring potential break-ins.
Casement crank windows are among the most energy-efficient window styles available. When closed, the sash presses tightly against the frame, creating an airtight seal that prevents drafts and air leaks. This helps to keep your home comfortable and reduce your heating and cooling costs.
Casement crank windows can be made from a variety of materials, each with its own benefits and drawbacks. Some of the most common materials include:
Wood:Traditional and timeless, wood casement windows offer a classic look and excellent insulation. However, they require regular maintenance to prevent rot and decay.
Vinyl:Vinyl casement windows are low-maintenance and energy-efficient, making them a popular choice for modern homes. They are available in a range of colors and finishes to suit your style preferences.
Aluminum:Aluminum casement windows are durable and resistant to rust and corrosion, making them ideal for coastal or humid climates. They are also lightweight and easy to operate.
Fiberglass:Fiberglass casement windows are extremely strong and energy-efficient, with excellent insulation properties. They are also low-maintenance and can be painted to match your home's exterior.
When it comes to the installation process, casement crank windows can be more complex than other window styles due to the crank mechanism and hardware. It's essential to hire a professional installer with experience in casement window installation to ensure proper fit and function.
Before installation, the installer will take precise measurements of your window opening to ensure a snug fit. They will then remove the old window and prepare the opening for the new casement window. This may involve repairing any damage to the surrounding frame or walls, as well as adding insulation and sealing materials to improve energy efficiency.
Once the opening is prepared, the installer will carefully fit the new casement window into place, ensuring that it is level and plumb. They will then secure the window in place using screws or nails, and install the crank mechanism and hardware. Finally, they will seal the perimeter of the window to prevent drafts and air leaks, and test the window's operation to ensure smooth and easy opening and closing.
Although casement crank windows are relatively low-maintenance, it's essential to perform regular upkeep to keep them looking and functioning their best. This includes:
Cleaning the window glass and frame regularly to remove dirt and debris.
Lubricating the crank mechanism and hinges periodically to ensure smooth operation.
Inspecting the window seals and weatherstripping for signs of wear or damage, and replacing them as needed to maintain energy efficiency.
Repainting or refinishing wood casement windows as needed to protect them from the elements and prevent rot and decay.
In summary, casement crank windows are a stylish and functional choice for any home. With their excellent ventilation, security, and energy efficiency features, they offer a range of benefits that make them an attractive option for homeowners. By understanding the history, design, materials, installation, and maintenance of casement crank windows, you can make an informed decision about whether they are the right fit for your home and lifestyle.
Casement windows are the most common style of window. They feature hinged panels that swing open and closed. Casement windows are available in single panels or multiple panels. The direction a door swings, either to the right or the left, is called the handing. In addition to handing, window are identified as either inswing or outswing depending on whether they open into the house or towards the outside.

This newly built private house is in Sydney, Australia. The area occupied by the fenestration system in our scheduled design drawings was up to more than 110 square meters. A wide range of design details made the perfect mix of modern aesthetics and traditional sophistication, the simulated vertical hung windows with tilt & turn opening systems in this home are absolutely breathtaking. SDLS (Simulated Divided Lites with Spacer Bar) brings some historical vintage feeling to the whole building without losing any energy saving performance. Long narrow fixed windows creating larger-than-life expenses, coupled with German high-end systems made this project stand out from the rest.
The client's idea was to maintain a certain vintage feel, and our aim was to meet the energy efficiency needs and standards of modern houses as much as possible while maintaining a retro design. Doorwin’s 61S simulated hung windows with tilt & turn openings is a respectful modernization of a classic architectural masterwork.
Why choose the tilt and turn opening method?
Because it generally has better air seals than sliding, single hung, or double hung window frames. Tilt and turn windows form a complete seal when fully closed, this means they are less prone to water leakage, and cold draughts and you’ll keep more of your heating indoors where it belongs. They can be opened in the upper tilt way to ventilate at a minimum opening status and are easy to clean outside of the glass; when there’s a good day, they can be opened as normal inward casement windows.
Our well-crafted bespoke systems enhance the functionality and panoramic view of this modern house.
Huge, fixed glass walls up to seven meters long and two meters high bring great lighting and open views, making it really refreshing to the mind. Five meters high long narrow windows give the whole building a contemporary aesthetic.
