New page

The term ‘barrier wall’ is used to refer to a system of external wall assembly that maintains weather-tightness by preventing the intrusion of air, water and vapour. Barrier walls rely on the integrity of the outermost surfaces and construction joints, and are considered a cost-effective alternative to cavity or solid wall assemblies.

The cladding material should be impervious to the elements. Common examples of barrier wall systems include:

* Single-skin metal wall panels.
* Solid-metal wall cladding.
* Precast concrete panels.
* Insulated metal-wall panels.
* Exterior insulation and finishing system (EIFS).

The exterior cladding in a barrier wall system can be easily integrated into the assembly and serves as the main drainage plane – the element exposed to the weather. This differs from a cavity wall system where the main drainage plane and defensive line against bulk rainwater penetration is inside the cavity.

Careful installation of a barrier wall is crucial as, in order for it to be effectively zero-tolerance, the joints between facing units must be well sealed. The gaskets and caulking must be installed so that no water and/or air vapour can leak inside the cavity and damage the building envelope. There are often complex interface details that require specialised installation by professionals.

As barrier wall systems are sealed, they lack the ability to ‘breathe’, which means that any moisture penetrating into the wall cavity cannot be removed. However, the concealment of the barrier wall means that its materials are not exposed to elements such as UV radiation, thermal movement or excessive wetting.

Although barrier wall systems often have a lower initial cost, since there are fewer materials and time required for installation, this should be considered alongside the fact that they require a relatively high level of routine maintenance to remain effective over time. This is because over time the continued exposure to wind and rain can degrade the seal and lead to failure.

An advantage of barrier walls is that the non-sequential way in which they tend to be installed makes them more accessible should inspection or repairs to the weather-resistant barrier behind the cladding be required.
