A door is a movable structural element used to control entry and exit to a space, separate two areas, or connect them. Doors serve multiple functions, including security, privacy, climate control, aesthetic enhancement and emergency escape. They consist of a door leaf, frame, hinges or a sliding mechanism, a locking mechanism, handle and knob, and seal and insulation.
Doors come in various types and materials. Interior doors facilitate movement between rooms, while exterior doors prioritize security and weather resistance. Fire doors resist fire and smoke for a specified period. Doors can be made of wood, steel, glass or PVC. Smart doors with UWB (Ultra-Wideband) technology can unlock automatically as you approach.
Several manufacturers produce doors, including Pella, Andersen, JELD-WEN, Therma-Tru, Masonite, and Simpson Doors. These companies offer a range of styles, materials, and features to suit different needs and budgets. Doors are available at home improvement stores like Lowe's and Home Depot, as well as specialized door retailers. Prices vary widely based on material, size, features, and brand. Some companies also offer custom door design services.
