A weather strip, also known as a weatherstripping or weatherseal, is a narrow strip of material used to seal gaps and prevent unwanted elements, such as drafts, moisture, dust, and insects, from entering a building. It is typically applied around doors, windows, and other openings to enhance insulation and energy efficiency.
Weather strips come in various materials, such as rubber, silicone, foam, or metal, and are designed to withstand weather conditions and temperature changes. They are affixed along the edges of doors and windows or within the frame to create a tight seal when the opening is closed. Weather strips play a crucial role in maintaining indoor comfort and reducing energy consumption by preventing air leaks and enhancing the overall insulation of a building.
