Everything You Need To Know About External Door Closers

As we go about our daily lives, we often overlook the simple mechanisms that make our surroundings function efficiently. One such overlooked yet essential component is the external door closer. This unassuming device plays a crucial role in ensuring the safety and security of buildings by ensuring that doors close properly and securely. In this article, we will delve into everything you need to know about external door closers.

What Is an external door closer?

An external door closer is a device that is installed on the exterior doors of buildings to automatically close the door after it has been opened. This ensures that the door is securely closed behind anyone entering or exiting the building. External door closers are commonly used in commercial buildings, schools, hospitals, and other public spaces to maintain security and energy efficiency.

How Does an external door closer Work?

External door closers operate on the principle of hydraulic or mechanical mechanisms that control the speed at which the door closes. When the door is opened, the door closer’s spring mechanism is activated, storing energy that is released when the door is released. This energy is translated into a closing force that gently guides the door back into the closed position.

External door closers are equipped with adjustable hydraulic valves that allow users to control the closing speed and force of the door. This ensures that the door closes smoothly and securely without slamming shut or causing damage to the frame or hinges.

Why Are external door closers Important?

External door closers play a crucial role in maintaining the security and safety of buildings. By ensuring that doors close properly and securely, external door closers prevent unauthorized access and intrusions into the building. Additionally, external door closers help in controlling the flow of foot traffic, especially in high-traffic areas, by ensuring that doors close behind individuals entering or exiting the building.

Furthermore, external door closers are essential for energy efficiency. By automatically closing doors, external door closers help in regulating the temperature within the building, thereby reducing the loss of heating or cooling energy. This can lead to significant cost savings on energy bills and contribute to a more sustainable environment.

Types of External Door Closers

There are several types of external door closers available in the market, each designed to meet specific requirements and preferences. The most common types of external door closers include:

1. Overhead Door Closers: These are the most common type of external door closers and are mounted on the top of the door frame. Overhead door closers are versatile and can be used on a wide range of door types and sizes.

2. Surface-Mounted Door Closers: Surface-mounted door closers are installed on the surface of the door rather than the frame. These types of door closers are often used in retrofit applications or on doors that do not have enough space for overhead installation.

3. Concealed Door Closers: Concealed door closers are hidden within the door frame or the door itself, providing a clean and seamless look. These types of door closers are often used in modern architectural designs where aesthetics are a priority.

4. Floor-Spring Door Closers: Floor-spring door closers are installed in the floor below the door. These types of door closers are commonly used on heavy or large doors that require extra support for closing.

Conclusion

External door closers may seem like a small and insignificant component of a building, but they play a significant role in ensuring security, safety, and energy efficiency. By automatically closing doors behind individuals, external door closers help in preventing unauthorized access, controlling foot traffic, and regulating the temperature within the building. With various types of external door closers available in the market, it is important to choose the right one that meets the specific requirements of the building and enhances its functionality.
