Fronttür

Fronttür is a term used to refer to the primary exterior door of a building, typically located on the front façade. It serves as the main access point, provides weather protection, and contributes to the architectural character of the facade. In German usage, the more common term is Haustür, while Fronttür is often encountered in cross-language contexts or descriptive discussions.

Construction and materials: Front doors are commonly made from wood, engineered wood products, steel, aluminum, or fiberglass-reinforced composites. They are set in a frame with weatherstripping and an insulating core to minimize heat transfer. Many front doors include glazing, sidelights, or transoms, and use reinforced hinges and multi-point locking systems for security.

Security and performance: For security, front doors may be rated under European standards for burglary resistance (such as RC ratings in EN 1627–1630) and feature robust locking hardware, reinforced frames, and anti-tamper features. Energy performance is assessed by the door's U-value and air, water, and wind resistance; high-performance doors minimize drafts and thermal bridging. Accessibility considerations often address threshold height and smooth transitions.

Design and maintenance: Styles range from traditional paneled doors to minimalistic flush doors, with various finishes and hardware to suit architectural taste. Maintenance involves preserving seals and finishes, inspecting hinges and locks, and re-sealing or repainting as needed. The choice of Fronttür affects curb appeal, security, and energy efficiency, and installation should ensure proper alignment with the frame and weatherproofing.
