About Door Bottoms, Thresholds & Seals
A door seal is a form of door weatherstripping used to seal cracks and gaps around the perimeter of a door. Similar to door thresholds, door seals prevent drafts, light, sound, smoke, fire, and humidity pollution from entering or exiting a room, house, or building. There are different seals for different structural needs and methods. Foam tape seals offer a quick and easy approach or you can use more durable seals such as a reinforced safety seal.
