Parapet

Definition

A parapet is a low wall or railing that protects the edge of a platform, roof, or bridge. It is the portion of an exterior wall that projects above the level of the roof.

Purpose

Parapets serve several purposes, including safety, aesthetics, and functionality. They prevent people from falling off roofs or platforms, provide a finished appearance to buildings, and can help in fire protection by acting as a barrier.

Examples of Use

• Building Roofs: Parapets on flat roofs to provide safety and conceal rooftop equipment.
• Bridges: Low walls on the edges of bridges to prevent vehicles and pedestrians from falling off.
• Terraces: Railings on terraces and balconies to ensure the safety of occupants.

Related Terms

• Balustrade: A row of balusters topped by a rail, often used along staircases and terraces.
• Cornice: A decorative molding at the top of a building, often below the parapet.
• Railing: A barrier consisting of rails supported by posts, typically used for safety on balconies and staircases.

Notes

• Design: Parapets can be plain or ornate, depending on the architectural style of the building.
• Height: The height of a parapet is typically regulated by building codes to ensure safety.
