What is the role of the astragal in a double door setup?

The role of the astragal in a double door setup is primarily to seal gaps between the two doors. When double doors are installed, there can be a space at the meeting point where the two doors come together. The astragal is a vertical component that is typically installed on the inactive door (the one that does not have the primary locking mechanism) and overlaps with the active door. This design helps to prevent air, water, and dust from entering through the gap, enhancing energy efficiency and improving the overall seal of the door system.

The astragal also helps mitigate noise and provides an additional layer of security. It is crucial in ensuring a tight fit between the doors when closed. This functionality is essential in various settings, such as residential homes or commercial buildings, where maintaining temperature and minimizing outside elements is important.
