Doors are not merely entryways; they are complex structures with various components that play crucial roles in functionality, security, and aesthetics. The terminology associated with these components can be overwhelming, but fear not!

Here is a comprehensive guide to help you understand the intricacies of commercial door openings, from single doors to double doors and everything in between.

Commercial Openings: Single and Double Doors Understanding the anatomy of a door begins with distinguishing between single and double doors.

 

Parts of a Door:

  1. Door Opening:
    • The designated area within a frame where doors are installed, available in single or double configurations.
    • Doors crafted from various materials, including wood, hollow metal, stainless steel, aluminum, and more.
    • Specialty doors like double acting, bullet-resistant, fire-rated, hurricane-resistant, and sound-resistant are offered by LaForce. Custom doors and frames can also be manufactured in-house.
  2. Active Leaf/Door and Inactive Leaf/Door:
    • Active leaf opens first and accommodates main operating hardware.
    • Inactive leaf opens after the active leaf and contains a strike to receive the lock/latchbolt of the active door.
  3. Frame:
    • Surrounds the door on three sides, anchored to the wall, and available in various materials.
    • Custom frames designed and manufactured by LaForce to meet specific building needs.
  4. Head (Of Frame) and Jamb (Of Frame):
    • Head is the horizontal portion above the door.
    • Jamb is the vertical frame component on either side of the door opening, forming the frame's perimeter.
  5. Hinges:
    • Vital hardware allowing door swing, available in various types, including mortise, continuous, and spring.
  6. Lock or Lock Set:
    • Complete latch assembly for door closure, including latch mechanism, cylinders, keys, and trim.
  7. Strike:
    • Metal plate or box receiving the bolt or latch of the lock to keep the door shut.
    • Electric strikes available for remote control or access control equipment.
  8. Closer:
    • Device attached to the top of the door regulating and controlling door swing.
    • Mechanical or electromagnetic options; essential for fire-rated doors.
  9. Lite and Lite Kit:
    • Lites or vision panels are glazed openings allowing light passage.
    • Lite kits secure door lite glass in place, available in metal, wood, or veneered options.
  10. Threshold and Sweep:
    • Thresholds close the gap between the door and the floor, aiding smooth transitions.
    • Sweeps, usually vinyl, seal the space beneath the door, keeping out cold air and elements.
  11. Astragal:
    • Strip of material closing gaps between a pair of doors, requiring coordinators for proper sequencing.
  12. Gasketing:
    • Seals the perimeter of the door opening, addressing environmental, sound, light, and smoke/fire control.
  13. Exit Device:
    • Also known as panic hardware, facilitates fast egress during emergencies.
  14. Louver:
    • Series of slats or blades at the bottom, allowing safe air passage through the door.
  15. Protection Plate:
    • Metal plates at the bottom protecting against wear and tear.
    • Various types include Kick Plates, Mop Plates, Armor Plates, and Stretcher Plates.
