Doors are essential elements in architecture, serving as barriers that provide security, privacy, and separation between spaces. They come in various materials like wood, metal, and glass, each offering unique benefits. Wooden doors are popular for their aesthetic appeal and versatility, while metal doors provide enhanced security. Glass doors, often used in modern designs, allow natural light to flow through spaces. In addition to their functional roles, doors also contribute to the overall style and atmosphere of a room, making them an important consideration in both home and commercial design.
