Types of Astragals: Overlapping and Meeting Stile
Astragals come in different types, each serving a specific purpose in sealing the gap between a pair of doors. The two main types of astragals are overlapping astragals and meeting stile astragals. Let’s take a closer look at each type.
Overlapping Astragals
Overlapping astragals are fastened to one door in a pair and overlap the edge of the other door when closed. They can be made of metal or bent to accommodate strike plates. Z-type overlapping astragals, for example, are attached to the inactive door and cover the gap between the doors. These astragals require the correct closing sequence of the doors for proper latching and security.
It’s important to note that overlapping astragals may require additional hardware such as door coordinators for self-closing same-swing pairs of doors. They should not be used with push/pull pairs or doors with vertical rod exit devices on both leaves. For doors with active leaf locksets, automatic flush bolts are recommended to ensure proper functionality.
Meeting Stile Astragals
Meeting stile astragals, on the other hand, meet in the middle when the doors are closed. They can be simple seals, adjustable seals, or magnetic strips designed to create a proper seal. Unlike overlapping astragals, meeting stile astragals allow independent opening of the doors without the need for a specific closing sequence.
When selecting the right astragal for your doors, consider the specific requirements and functionality of your doors. Overlapping astragals provide increased security but may require additional hardware and coordination. Meeting stile astragals allow both leaves to remain active and provide a seal in the middle. Consulting with a sales representative or referring to the door manufacturer’s listing can help you make the best choice for your doors.
Uses and Applications of Astragals
Astragals have a wide range of uses and applications in the door industry. They are commonly applied to commercial double and single doors, as well as various other spaces such as retail stores, offices, classrooms, restaurants, and industrial settings. In the case of double doors, the astragal is typically attached to the vertical meeting edge of one door leaf. Depending on the function and application, it can be attached to either the active or inactive leaf. This ensures a secure seal between the doors when closed.
Astragals also play a crucial role in enhancing the security of single doors. By overlapping the frame face, they provide an additional layer of protection. This is especially important for fire-rated pairs of doors and fire-rated Dutch doors. In these situations, astragals are essential for meeting the stringent safety requirements.
Benefits and Properties of Astragals
Astragals offer a range of benefits that make them a valuable addition to any door. One of the primary advantages of astragals is increased security. By sealing gaps between doors, they make it difficult for intruders to tamper with locks, providing an added layer of protection for homes, offices, and other establishments. With astragals in place, you can have peace of mind knowing that your doors are more secure.
Astragals also offer enhanced privacy. By preventing the passage of sound and light, they create a barrier that keeps conversations private and ensures that light from outside does not enter the room. This is especially beneficial for areas that require confidentiality, such as meeting rooms or private offices. With astragals, you can create a more secluded and secluded space.
In addition to security and privacy, astragals provide excellent weather protection. By sealing out air, water, and debris, they help keep interior spaces free from drafts, dust, and other outdoor elements. Furthermore, in the event of a fire, astragals can be instrumental in containing smoke, flames, and gases, potentially saving lives and property. They act as an essential barrier that prevents the spread of fire and its associated dangers.
Energy Efficiency and Aesthetics
Astragals also contribute to energy efficiency. By reducing drafts and heat loss, they help maintain a comfortable indoor environment while minimizing energy consumption. The proper installation of astragals can provide insulation, keeping the temperature regulated and reducing the need for excessive heating or cooling. This not only saves energy but also reduces utility costs.
Beyond their functional benefits, astragals add a touch of aesthetic appeal to doors. With various customization options available, you can choose astragals that match the architectural style of your space. Whether you prefer a sleek and modern design or a more traditional look, astragals can be customized to blend seamlessly with the overall aesthetic of your doors.
Overall, astragals offer a multitude of benefits, ranging from increased security and privacy to weather protection and energy efficiency. Their versatility and ability to enhance both functionality and aesthetics make them a valuable addition to any door. Whether you’re looking to improve security, enhance privacy, or create a more energy-efficient space, astragals are a solution worth considering.
Selecting the Right Astragal for Your Doors
When it comes to choosing the perfect astragal for your doors, there are a few key considerations to keep in mind. First and foremost, you’ll want to assess the specific properties of the astragal. Factors such as material, size, and design will play a role in determining its effectiveness and longevity. Whether you opt for an overlapping astragal for enhanced security or a meeting stile astragal for convenient independent opening, understanding the unique properties of each type will help you make an informed decision.
Security is another critical aspect to consider. Depending on the level of security required, different astragal options may be more suitable. Overlapping astragals provide an extra layer of protection by sealing gaps and preventing tampering with door locks. On the other hand, meeting stile astragals allow both door leaves to remain active, offering flexibility without compromising security.
It’s essential to refer to the door manufacturer’s listing or specifications to ensure you select the right astragal for your specific doors. Manufacturers often provide guidance on the recommended type of astragal, particularly for fire-rated doors. Compliance with model building codes and compatibility with existing hardware are also key factors to evaluate. If you have any uncertainties, consulting with a knowledgeable sales representative will help you make an informed decision that aligns with your requirements.
