A parapet is a barrier or low wall that extends above the edge of a roof, balcony, walkway, or other structure . It is designed to provide a safety barrier to prevent falls from heights and to protect the building and its occupants from wind, rain, and other environmental elements.
Types of Parapets
There are several types of parapets used in Australian commercial construction projects, including:
- Stepped parapets: These are used for inclining structures and add a staircase design along the roof's incline for a more aesthetic look .
- Flat roof parapets: These are walls built around the edge of a flat or low-slope roof, typically with cap flashings and scuppers installed .
- Parapet roofs: These are type of roofing system that extends beyond the edge of the main roof, providing additional space that can be used as a patio or walkway .
Parapets serve several purposes, including:
Safety: They provide a safety barrier to prevent people from accidentally falling off the edge of a roof or elevated platform.
Aesthetic: Parapets can enhance the architectural appearance of a building by adding visual interest or concealing rooftop equipment like HVAC systems.
Fire Protection: In some cases, parapets are designed to act as fire barriers, helping to prevent the spread of fire between adjoining buildings or different sections of the same building.
Weather Protection: They can help in directing rainwater away from the roof surface, often working in conjunction with a drainage system to prevent water ingress and damage.
In the context of Australian construction standards, parapets must comply with specific building codes and regulations to ensure they meet safety and structural integrity requirements. These regulations may dictate the minimum height, materials, and construction methods used for parapets in commercial buildings.
