door shoe
A door shoe is a protective and insulating component installed at the bottom of the door. It typically consists of a metal or aluminum channel that fits snugly over the door's lower edge, with a weather-resistant sweep or gasket attached. The door shoe helps seal the gap between the door and the threshold, preventing drafts, moisture, dust, and insects from entering. It enhances energy efficiency, provides additional weatherproofing, and often includes adjustable features to accommodate varying door heights and thresholds. This component is essential for maintaining the longevity and functionality of iron doors in different environmental conditions.
