In the construction and interior design industry, door closers play a crucial role in ensuring that doors close automatically after being opened. These devices are essential for maintaining the security, functionality, and longevity of doors, making them a must-have in both commercial and residential buildings. However, there are various types of door closers, each designed for specific installations and applications. Understanding the differences can help you select the right product for your needs.
1. What is a Door Closer?
A door closer is a mechanical device that automatically closes a door after it has been opened. It prevents the door from slamming shut, reduces the impact of wind, and helps keep spaces secure by ensuring that doors are always closed after use. Door closers are commonly used in environments that require the door to close on its own, such as offices, hospitals, and hotels.
2. Concealed Door Closers (Perco or Perkomatic Closers)
One of the more discreet options for door closers is the concealed door closer, which is typically installed inside a pocket within the door frame (also called the door jamb). These closers are often referred to as Perco closers or Perkomatic closers.
Concealed door closers are ideal for installations where aesthetic appeal is a priority. Since the closer is hidden within the door frame, the external appearance of the door is cleaner and more streamlined. This type of closer is perfect for modern buildings or high-end interiors where visibility of mechanical devices needs to be minimized.
3. Transom Door Closers
Another widely used type of door closer is the transom door closer, which is mounted at the top of the door frame, typically in the header. These closers are generally more visible than concealed ones but offer robust functionality. Transom closers come in two main variants: Hold Open (HO) and Non-Hold Open (NHO).
- Hold Open (HO) Transom Closers: This type of closer allows the door to remain in an open position once fully opened. It’s ideal for environments where doors need to be kept open for extended periods, such as in conference rooms, restaurants, or hospitals. This feature is particularly useful in high-traffic areas where manual door operation would be cumbersome.
- Non-Hold Open (NHO) Transom Closers: As the name suggests, NHO closers do not allow the door to stay open. Once the door is opened, the closer will automatically pull the door shut. NHO closers are perfect for spaces where doors must always close, such as in offices, corridors, or fire-rated doors.
4. Types of Door Closers: Which One to Choose?
When choosing the right door closer for your needs, several factors should be considered:
- Door Weight and Size: The weight and size of the door play a critical role in determining the type of closer required. Larger and heavier doors typically need more powerful closers to ensure smooth operation.
- Environment and Use: Different environments may have different demands. For instance, a hospital might require a hold-open closer for doors in high-traffic areas, while a security office may prioritize a non-hold open closer to ensure the door is always closed.
- Aesthetics and Concealment: If your project requires a sleek and modern look, concealed closers are a great option. However, if function takes precedence and the closer will be visible, a transom closer might be the better choice.
5. Why Are Door Closers Important?
- Security: Door closers ensure that doors close securely after each use, preventing unauthorized access.
- Safety: In the case of fire-rated doors, door closers are crucial for maintaining safety by preventing the spread of fire and smoke.
- Energy Efficiency: By ensuring that doors close properly, door closers help improve energy efficiency by maintaining temperature control within the building.
- Durability: Door closers help prolong the life of doors by reducing the physical wear that comes from doors being left open or slammed shut.
6. Conclusion: Choosing the Right Door Closer
Selecting the right type of door closer is essential to ensure the functionality, safety, and aesthetics of your building. Whether you’re choosing a concealed Perco closer for its sleek design, or a transom closer for its superior control, understanding the different types of door closers and their applications will help you make an informed decision.
For businesses involved in construction, renovation, or architectural design, providing clients with high-quality and reliable door closers is a great way to enhance the overall experience of a building. Ensure you choose a door closer that aligns with the specific needs of your space, taking into account the door’s size, the required functionality, and aesthetic preferences.
