Types of Door Frame Parts
Sill
The sill is a critical component of the door frame, primarily found in exterior doors. It acts as the foundation for the door, preventing water and drafts from seeping into your home. The sill is often sloped to channel water away from the door, ensuring longevity and performance.
Threshold
The threshold serves as a transition between different areas. It not only enhances the aesthetic appeal but also provides insulation and a barrier against drafts. Depending on the type of door—whether it’s an entry door or a patio door—the threshold may vary in height and material.
Door Sweep
A door sweep is a flexible strip usually made of rubber or vinyl that attaches to the bottom of the door. It seals the gap between the door and the floor, preventing drafts, dirt, and pests from entering your home. This component is essential in maintaining energy efficiency and comfort.
Door Jamb
The door jamb consists of vertical frames that surround the door. It provides structural support and stability while allowing the door to pivot smoothly. Understanding the door jamb’s role is crucial when selecting a door or planning renovations, as the size and material directly affect the door’s performance.
Head
The head is the upper horizontal member of the frame. It may include decorative elements and often has a stop to help the door close securely. The head is vital for providing a sturdy overhead structure that complements the door’s design and function.
Margins
Margins are the gaps between the door and the frame. Proper margins ensure that the door can open and close without obstruction. Too small margins can cause the door to stick, while too large margins may allow drafts and noise to penetrate.
Astragal
The astragal is a vertical strip used in double doors to create a seal between them. It prevents air and light from passing through the gap, enhancing insulation and privacy. Installing an astragal is particularly beneficial for exterior double doors.
