An example of a barrier wall is metal siding.
Barrier walls are building components designed primarily to protect a structure from the elements, often using a single layer or element. They act as the first line of defense against weather conditions like rain, wind, and temperature fluctuations. According to the provided reference, examples of protective wall barriers include:
- Metal siding
- Panels
- Curtain walls
These systems are engineered to shed water from the exterior surface and prevent it from penetrating the building envelope.
Understanding Barrier Wall Examples
Let's look at some common types based on the examples given:
- Metal Siding: This involves attaching metal sheets or panels to the exterior frame of a building. It's known for its durability, low maintenance, and ability to effectively repel water.
- Panels: This can refer to various types of pre-fabricated panels used as exterior cladding. Examples include composite panels, cement board panels, or other engineered materials designed for weather protection. These panels are often joined with seals or gaskets to create a continuous barrier.
- Curtain Walls: Often used in modern commercial buildings, curtain walls are non-structural outer walls that simply keep the weather out and occupants in. They are typically made of glass or metal panels supported by a lightweight frame system. While primarily a barrier, curtain walls can also include elements for insulation and air sealing.
Some barrier wall systems might also incorporate additional layers, such as a separate vapor barrier, depending on the climate and building design requirements.
Functions of Barrier Walls
Barrier walls serve crucial functions in building construction:
- Weather Protection: Shielding the building from rain, snow, wind, and UV radiation.
- Energy Efficiency: Contributing to thermal performance by reducing air leakage and sometimes incorporating insulation layers.
- Durability: Providing a robust exterior finish that can withstand environmental stresses.
Barrier walls are distinct from drainable or cavity walls, which are designed to manage water that does penetrate the exterior layer by directing it away from the building structure.
