They are typically made from materials like wood, fiberglass, or steel, each offering different levels of durability and energy efficiency. Exterior doors can come in various styles, including traditional, modern, and decorative designs, allowing homeowners to choose one that complements their home's architecture. These doors often feature additional components such as door frames, locks, and weather stripping to enhance their functionality. Proper installation and maintenance are essential to ensure they perform well against the elements and provide adequate security. Choosing the right exterior door can significantly impact a home's overall energy efficiency and curb appeal.
