Casement Window: Everything You Need to Know
Over the decades, casement windows still are a popular option for homeowners. And, with its simple design and excellent performance, the aluminum swing window is widely used in the world. Then, in this post, the author would explore some of the most common questions regarding casement windows to let you get a further understanding of your house window.
What is Casement Window?
A casement window is a type of window that is hinged on one side and swings outward, either to the left or the right, to open and close. Casement windows are typically operated using a crank or a lever, which is used to push the window open or pull it shut. They are popular in many parts of the world, especially in Europe, where they have been used for centuries.
Currently, casement windows are often made from aluminum, although they can also be made from other materials such as uPVC or aluminum. They are typically designed to be energy efficient, with multiple panes of glass and insulated frames. This helps to keep out drafts and noise and to reduce energy costs by improving insulation.

Do Casement Windows Have Screens?
Yes, casement windows can have screens. Screens are essential for keeping insects out while still allowing fresh air to circulate throughout the home. Casement windows typically have screens on the inside, which makes them easy to remove and clean.
Are Casement Windows Energy Efficient?
Yes, they are energy efficient! Casement windows are known for their energy efficiency. When the window is closed, the sash presses tightly against the frame, creating a tight seal that helps to prevent air leakage. Also, the aluminum clad casement windows have a strong seal on all four sides, so the warm air in the house is not easy to escape to the outside. Therefore, they can help to keep warm air in during the winter and cool air in during the summer.
Are Casement Windows Safe?
The casement window is absolutely safe. And, it even is regarded as one of the safest types of windows for a home, because of its special design. In the following section, the author would illustrate the casement window security.
●The casement window also called an aluminum swing window has a sealing design. The window frame is designed to be tightly sealed when it’s closed and latched.
●The casement window, even the casement window with grids only allows people to open it from the inside.
●Casement windows can not be opened from the outside, even with the use of a crowbar. The only method to break into a home through the casement window is by breaking the glass screen in the windows. However, once breaking the casement window with screen, it would produce noise to alarm other people.

Are Casement Windows Better?
The comparison between casement windows and other types of windows is subjective and depends on the homeowner's specific needs and preferences. Casement windows offer many benefits, such as increased ventilation, energy efficiency, and easy operation. Furthermore, they are low-maintenance and can last for many years with proper care.
Are Casement Windows More Expensive Than Double-Hung Windows?
Typically, casement windows cost twice as much as double-hung Windows. It attributes to the use of hardware and labor cost. Here is the analysis.
First, due to the more complex mechanical operations in casement windows, the casement window with screen requires more hardware and is more labor-intensive to install, including hinges, locks, and cranks. The hardware needed to operate a casement window is often more complex and costly than that of a double-hung window, which can drive up the cost. Additionally, casement windows require more precise installation than double-hung windows, as the hinges and cranks must be precisely aligned for the window to function properly. This precision installation can result in higher labor costs, further increasing the price of the windows.
Second, casement windows often feature higher-quality materials, such as solid wood or vinyl, which can drive up the cost. It also includes things like thicker glass, heavier-duty frames, and more durable hardware. While these materials can add to the cost of the windows, they can also increase their lifespan, which can provide long-term cost savings.
The third reason why casement windows are more expensive than double hung aluminium windows is energy efficiency. The double hung aluminium windows are not as good as the casement windows in the leakage. Then, in order to prevent air leakage, the double hung windows including aluminum double hung windows and commercial single hung aluminum window need to be equipped with additional insulation or weatherstripping.

Do Casement Windows Open In or Out?
Casement windows can open either inwards or outwards, depending on how they are designed and installed.
●Inward-opening casement windows are hinged on the side and swing inward the interior, like a door. This design is classic and is commonly seen in European countries, where it is often used for windows that are flush with the building facade. This opening method in the triple glazed casement windows can be easier to clean from the inside and provide better ventilation control.
●Compared with the inward-opening casement windows, the swing out window usually is hinged on the opposite side and swings outwards, away from the room. This design in the aluminum swing window is commonly used in North America, where it is often used for windows that are set back from the building facade. This type of aluminum swing window can provide better protection against rain and wind, and can also be easier to operate in areas with heavy snowfall.
Here is a visual illustration of the two types of casement windows:

As shown in the illustration, inward-opening casement windows swing into the room, while outward-opening casement windows swing outwards. The hinge placement and direction of the swing will determine which type of casement window you have.
Conclusion
All in all, because of its special design and practical functions, the aluminum swing window still takes the dominant position in the house window market. Although it is more expensive than double-hung windows, it is still a wise investment for those seeking an energy-efficient and long-lasting window option.
