Understanding Different Types of Walls in Buildings

Buildings use various types of walls, each serving a specific function based on its location and construction. These walls can be load-bearing, non-load-bearing, tall, short, interior, or exterior.

The question specifically asks about a short height wall constructed above the Roof Slab in an open terrace. Let's examine the given options to identify the correct term for this specific type of wall.

Identifying the Short Height Wall on a Roof Slab

The short height wall located on top of a roof slab, typically in an open terrace area, serves important purposes such as safety, preventing people from falling off the edge, and also protecting the roof structure. Let's break down the options:

What is a Parapet Wall?

A Parapet Wall is a low protective wall built along the edge of a roof, balcony, bridge, or other structure. Its primary purpose is to prevent falls and provide a barrier. On a roof slab, especially in an open terrace, a short wall performing this function is indeed called a Parapet Wall.

• Location: Constructed along the perimeter of a roof slab, balcony, or terrace.
• Height: Typically short height, ranging from about 1 meter to 1.5 meters, or sometimes less depending on local building codes.
• Purpose: Safety (preventing falls), aesthetic finish, wind barrier, preventing water runoff directly over the edge.

Why Other Options are Not Applicable Here

Let's consider the other options and understand why they don't fit the description of a short height wall on a roof slab in an open terrace:

Boundary Wall

A Boundary Wall is a wall that defines the boundary or perimeter of a property. It separates one plot of land from another. It is typically built at ground level around the entire property and is not specific to a roof slab.

• Location: Around the perimeter of a property or plot of land.
• Purpose: Security, privacy, marking property limits.

Partition Wall

A Partition Wall is a non-load-bearing wall used to divide internal spaces within a building. These walls are typically built within the floors of a building to create rooms and are not located on the roof slab to define an open terrace edge.

• Location: Inside a building to divide rooms or areas.
• Purpose: Space division, privacy within interior spaces.

Plinth Wall

A Plinth Wall is the part of the wall structure built from the top of the foundation up to the plinth level (the level of the finished ground floor). It is constructed at the base of the building, above the foundation, and is not located on the roof slab.

• Location: At the base of the building, above the foundation, up to the ground floor level.
• Purpose: Transfers load from the walls above to the foundation, protects against dampness.

Comparing the Wall Types

Here is a summary comparing the different types of walls discussed:

Based on the descriptions, the wall constructed above the Roof Slab in an open terrace, serving as a safety barrier, is clearly identified as a Parapet Wall.

Additional Information on Parapet Walls

Parapet walls are important architectural and safety features. They can be constructed from various materials like brick, concrete, or stone, often matching the building's facade. The height of a parapet wall is often regulated by building codes to ensure adequate safety.

Beyond safety, parapet walls can also serve functional purposes like concealing rooftop mechanical equipment or providing a base for railing systems. A well-designed parapet wall contributes to both the functionality and the visual appeal of a building.
